Last question anybody can help??

Answer:

the answer is C.

Step-by-step explanation:

Put both equations in the slope intercept form of the line and then graph to estimate where the lines cross.

y = mx + b

7x - y = 7   The 7x is on the wrong side of the equal sign, so subtract 7x from both sides of the equation

7x - 7x -y = -7x + 7

-y = -7x + 7  We want the equation to start y = , not -y =. so divide all the way through by -1

[tex]\frac{-1y}{-1}[/tex] = [tex]\frac{-7x}{-1}[/tex]  + [tex]\frac{7}{-1}[/tex]

y = 7x - 7

x + 2y = 6   The x is on the wrong side of the equal sign.  Subtract x from both sides

x -x + 2y = -x + 6

2y = -x + 6  Divide all the way through by 2

[tex]\frac{2y}{2}[/tex] = [tex]\frac{-1}{2}[/tex]x + [tex]\frac{6}{2}[/tex]

y = [tex]\frac{-1}{2}[/tex] x + 3

Step-by-step explanation:

The cost of one dinner without any sides is $2, and the cost of 6 dinners without any sides is 6 times that amount, which is $12. Answer: $12.

An equation is a statement that asserts the equality of two expressions. Equations typically contain one or more variables, which are quantities that can take on different values. The goal of solving an equation is to find the values of the variables that make the equation true.Equations can take many different forms, but some common types include linear equations, quadratic equations, polynomial equations, and exponential equations.

An expression is a combination of numbers, variables, and mathematical operations that represents a value. Expressions can contain constants, variables, and operators, such as addition, subtraction, multiplication, and division.

In the given question,

There are different ways to approach this problem, but one possible method is to use ratios. Let's assume that the cost of a dinner without any sides is x dollars. Then, the cost of a dinner with salad is x plus some additional amount for the salad, which we don't know yet. Let's call this additional amount y dollars. Therefore, the cost of a dinner with salad is x + y dollars.

According to the problem, Russell can buy 6 dinners with salads for $114. This means that the total cost of 6 dinners with salads is $114. We can write this as an equation: 6(x + y) = 114

Simplifying this equation, we get: 6x + 6y = 114

Dividing both sides by 6, we obtain: x + y = 19

Now we need to find the cost of 6 dinners without any sides, which is 6 times the cost of a dinner without any sides. We already know that the cost of one dinner without any sides is x dollars, so the cost of 6 dinners without any sides is 6x dollars.

To find x, we can use the fact that x + y = 19, which we derived from the given information. We don't know y, but we can express it in terms of x by using the fraction of the salad price to the total price of a dinner with salad. From the long division, we have:

2x - 3

x + 1

This means that y is equal to the remainder of the division, which is -3/(x+1). Therefore, we have: y = -3/(x+1)

Now we can substitute this expression for y into the equation x + y = 19:

x - 3/(x+1) = 19

Multiplying both sides by x+1, we get: x(x+1) - 3 = 19(x+1)

Expanding the products and simplifying, we obtain a quadratic equation:

x^2 + 18x - 22 = 0

We can solve this equation by using the quadratic formula:

x = (-18 ± √(18^2 + 4122)) / (2*1)

x = (-18 ± √(400)) / 2

x = (-18 ± 20) / 2

x = -9 or x = 2

Since we are interested in the cost of a dinner without any sides, which should be a positive number, we discard the negative solution and take x = 2. Therefore, the cost of one dinner without any sides is $2, and the cost of 6 dinners without any sides is 6 times that amount, which is $12. Answer: $12.

An algebraic equation is a method of connecting two quotes by using the equals symbol (=) to express equality. In algebra, an explanation is a definitive expression that verifies the equivalency of two formula. For example, the identical character divides the numbers 3x + 5 and 14. A linear equation might be used to recognize the connection that existing between the texts written on separate sides of a letter. The product and application both frequently the same. 2x - 4 equals 2, for example.

We can factor out x to get the answer to the equation Ax2 - 3x = 0.

x(Ax - 3) = 0

We can set each factor to zero and solve for x because the product of two factors is zero if and only if one or both of the factors are zero.

x = 0 or Ax - 3 = 0

If A is greater than zero, we can solve the second equation for x by adding 3 to both sides and dividing by A:

[tex]Ax-3 = 0 Ax-3 = 3 x = 3/A[/tex]

The solution for the equation ax² - 3x = 0 are x = 0 and x = 3/a.

The equals sign (=), which expresses equality, is a way to join two quotes in an algebraic equation. An explanation in algebra is a conclusive phrase that confirms the similarity of two formulas. The same letter, for instance, divides the integers 3x + 5 and 14.

The relationship between the texts written on the different sides of a letter can be determined using a linear equation. Products and applications are usually interchangeable. In this case, 2x - 4 equals 2.

From the question,

We can factor out x to get the answer to the equation ax² - 3x = 0.

x (ax - 3) = 0

The product of two factors is zero if and only if one or both of the factors are zero, thus we can set each element to zero and find x.

x = 0 or ax - 3 = 0

By adding 3 to both sides and dividing by a, we may solve the second equation for x if a is greater zero:

ax = 3

⇒ x = 3/a

Therefore, the solutions of the equation are x = 0 and x = 3/a.

The box and whiskers plot is made up of five points: the minimum, the first quartile (Q1), the median (Med), the third quartile (Q3), and the maximum. The minimum is the lowest value in the dataset and the maximum is the highest value in the dataset.

Median is the middle number in a set of numbers when the numbers are arranged in order from least to greatest. It is a type of measure of central tendency, which provides an indication of the “middle” value in a set of numbers. It is often used to measure the average of a set of numbers, particularly when there are extremely large or small values in the set.

The box and whiskers plot for this set of data is a visual representation of the data that makes it easier to interpret. The first quartile is the value that is 25% of the way through the dataset and the third quartile is the value that is 75% of the way through the dataset. The median is the middle value in the dataset.

To create a box and whiskers plot for this set of data, the minimum is 2, the first quartile is 4, the median is 5, the third quartile is 10, and the maximum is 14. The box and whiskers plot would then be represented by the following graph:

|                                 |

|    |    |    |    |    |    |    |    |    |    |

|  2 |  4 |  5 | 10 | 14 |

The box and whiskers plot graphically illustrates the spread of the data and allows us to easily compare the data to other datasets. It is also useful for identifying outliers in the dataset, as any value outside of the box and whiskers plot is considered an outlier.

The value of the length of the segment TM when JM is parallel to ST is 5 cm. Option B is the correct answer.

When two lines in a plane do not cross at any point, they are said to be parallel. Lines that never cross paths with one another and do not have a common junction point are said to be parallel. Lines can either be parallel or intersecting. Two lines are said to intersect when they cross at a certain location in a plane. A line is referred to as a transversal line if it crosses two or more other lines at different locations.

Given that, JM is parallel to ST.

We know that a parallel line inside the triangle divides the corresponding sides in equal ratio.

Thus,

JR/SJ = MR/TM

Substituting the values we have:

The probability that the sample proportion is between 0.55 and 0.62 is 0.7962.

Probability is the measure of how likely an event is to occur out of the total number of possible outcomes. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Probability is used to describe random events, such as the toss of a coin or the role of a die, as well as more complex events, such as the weather, stock market performance, and the success of a political candidate. A probability of 0.5, for example, means that there is a 50% chance that the event will occur.

This is calculated using the binomial probability formula, which is the probability of a certain outcome of a series of independent binary events. According to the formula, the probability of the sample proportion being between 0.55 and 0.62 is the sum of the individual binomial probabilities for each outcome within the range of 0.55 and 0.62. This is calculated as the sum of the binomial probabilities for each outcome (where p = 0.60): P(x=55) + P(x=56) + P(x=57) + P(x=58) + P(x=59) + P(x=60) + P(x=61) + P(x=62). The result is 0.7962.

Savings account: $32,436.

Owned equipment: $20,700.

Accounts receivable: $15,640.

Property value: $225,678.

Hence the sum of the assets is given by:

Assets = 48760 + 126790 + 32426 + 20700 + 15640 + 225678 = $469,994.

The debts of the company, with it's values, are given as follows:

Small Business Loan: $76,400.

Building Mortgage: $189,429.

Other debt: $16,970.

Hence the sum of the debts is given by:

A pοint where twο lines meet prοduces an angle.

The breadth οf the "οpening" between these twο rays is referred tο as a "angle". It is depicted by the figure.

Radians, a unit οf circularity οr rοtatiοn, and degrees are twο cοmmοn units used tο describe angles.

By cοnnecting twο rays at their ends, οne can make an angle in geοmetry. The sides οr limbs οf the angle are what are meant by these rays.

The limbs and the vertex are the twο main parts οf an angle.

We can see that

∠3 = ∠4                               ⇒ CPCT, As ΔDBA ≅ ΔDBC, SAS theorem

∠5 = ∠6                              ⇒ Isosceles triangle, thus two angles are equal

∠1 + ∠2 + 133 = 360°          ⇒ angle sum theorem

Now,

∠3 = 180 - 133 + 22

∠3 = 25°

also,

∠4 = 25°

Now,

∠1 = 133°     ⇒  CPCT

∠2 = 360 - (133 + 133)

∠2 = 94°

Now, ∠5  =  ∠6

As 180 - ∠2 = ∠5 + ∠6

180 - 94 = ∠5 + ∠6

180 - 94 = ∠5 + ∠6

86 = ∠5 + ∠6

2∠5 = 86

∠5 = 86/2

∠5 = 86/2

∠5 = 43°

There are initially 150 pharaoh ants in Southeast Asia, and every year the population increases by 950,000 ants.

The rate of change of a function refers to how much the output of the function changes with respect to changes in its input, typically expressed as the derivative of the function.

The initial value of a function refers to the value of the function at a specific point in its domain, often denoted as f(0) or f(x_0) for some value x_0 in the domain. It is called "initial" because it is usually the starting point for analyzing the behavior of the function over a range of inputs.

The given function is y=-150x+950,000, where x represents time in years and y represents the total population of pharaoh ants in Southeast Asia.

The initial value of the function is the y-intercept, which is 950,000. This means that at the beginning of the observation period (when x=0), there are 950,000 pharaoh ants in Southeast Asia.

The rate of change of the function is the coefficient of x, which is -150. This means that every year, the population decreases by 150,000 ants. Therefore, option A is correct because it states that the population decreases every year by 150,000 ants, which is the same as -150 multiplied by 1,000.

Rearranging the terms, we get:

p^2 + 6p + 4q^2 + pq + 4q + 48

Now, we can group the first three terms and the last three terms together as follows:

(p^2 + 6p + 9) + (4q^2 + pq + 4q + 39)

The first group can be factorized as a perfect square trinomial:

(p + 3)^2

The second group can be factorized by grouping the first two terms and the last two terms:

(pq + 4q) + (4q^2 + 39)

We can factor out q from the first two terms, and 4 from the last two terms:

q(p + 4) + 4( q^2 + 9)

Now, we can factor the second group as a sum of squares:

q(p + 4) + 4(q + 3)(q - 3)

Therefore, the fully factorized form of the expression is:

(p + 3)^2 + q(p + 4) + 4(q + 3)(q - 3) + 48

Note that this expression cannot be simplified further.
