Step-by-step explanation:

The inequality for which the order pair (-5, -7) is a solution will be x + y ≤ 3. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Let's check all the options, then

A)  y ≤ (1/4)x - 1

At (-5, -7), we have

-7 ≤ (1/4)(-5) - 1

-7 ≤ -2.25

This is incorrect.

B)  x + y ≤ 3

At (-5, -7), we have

-5 + (-7) ≤ 3

-12 ≤ 3

This is correct.

The inequality for which the order pair (-5, -7) is a solution will be x + y ≤ 3. Then the correct option is B.

The mean of the given sample data is 210, and the standard deviation is 7.937.

Given size 'n' = 300

The population proportion 'p' = 0.7

Let 'x' be the random variable of the binomial distribution

a)  mean of the binomial distribution  = n p = 300 × 0.7

                                                              μ  = 210

b)  variance of the binomial distribution

⇒ n p q

⇒ 300 × 0.7 ×0.3

⇒ σ² = 63

The standard deviation of the binomial distribution:

⇒ √n p q = √63 = 7.937

Answer:  $8.64 and $7.79 respectively.

Step-by-step explanation: To determine the cost of one pizza and one cheeseburger, we can set up the following system of equations:

3p + 2c = 41.50

2p + 5c = 43.25

The first equation represents the total cost of the Milleman Family's meal, where 3p represents the cost of 3 pizzas, 2c represents the cost of 2 cheeseburgers, and 41.50 represents the total cost of the meal. The second equation represents the total cost of the Anderson Family's meal, where 2p represents the cost of 2 pizzas, 5c represents the cost of 5 cheeseburgers, and 43.25 represents the total cost of the meal.

By solving this system of equations, we can determine the cost of one pizza and one cheeseburger. For example, we can use the elimination method to solve the system of equations as follows:

First, we can multiply the first equation by 5 and the second equation by 3 to get the following equations:

15p + 10c = 207.50

6p + 15c = 129.75

Next, we can subtract the second equation from the first equation to eliminate the c terms and find the value of p as follows:

15p + 10c = 207.50

6p + 15c = 129.75

9p = 207.50 - 129.75

9p = 77.75

p = 77.75 / 9

p = 8.64

Finally, we can substitute the value of p that we found into one of the original equations to find the value of c as follows:

3p + 2c = 41.50

3(8.64) + 2c = 41.50

25.92 + 2c = 41.50

2c = 41.50 - 25.92

2c = 15.58

c = 15.58 / 2

c = 7.79

Therefore, the cost of one pizza is $8.64 and the cost of one cheeseburger is $7.79.

Which expression is equivalent to 27 + 63 ?

3(9 + 18)

9(3 + 7)

21(7 + 3)

The interest on the bill will be calculated as follows:

Amount of Loan = $550

Sales Tax = 6% of $550 = $33

Total Loan = $550 + $33 = $583

Interest = 13.25% APR x $583 = $77.13

Late fee = $29

Total Interest = $77.13 + $29 = $106.13

Answer:2.25 or 9/4

Answer:

The combined amount of chocolate and regular milk sold was 52 cartons.

Step-by-step explanation:

1. Divide

36 ÷ 9 = 4

(This means that the ratio has a unit rate of 4. That means):

2. Second ratio rate

4 x 4 = 16

(Because the unit rate is 4).

3. Add

(Now, we add the original 36 cartons with the 16 cartons we found because the first step was just for finding the unit rate).

36 + 16 = 52 cartons.

The slope of the given line, 3x - 5y = 15, is 3/5 and the y-intercept is -3

From the question, we are to determine the slope and y-intercept of the given line.

The given line is

3x - 5y = 15

To determine the slope, we will write the equation in the slope-intercept form of a line.

The slope-intercept form of a line is given as

y = mx + b

Where m is the slope

and b is the y-intercept

Now, we will express the given equation in this form

3x - 5y = 15

-5y = 15 - 3x

Divide through by - 5

y = -3 + 3/5x

y = 3/5x - 3

By comparing to the slope-intercept form of a line,

m = 3/5

and b = -3

Hence, the slope is 3/5 and the y-intercept is -3

Answer:

y = 2(x-3)^2-2

Step-by-step explanation:

We can find the quadratic equation by using the vertex form.  The vertex form of a quadratic equation is:

[tex]y=a(x-h)^2+k[/tex], where x and y are any point on the parabola, a is the constant (indicating whether the parabola opens up or down), and h and k are the coordinates of the vertex.

Since we already have the y-int (an x and y coordinate lying on the parabola) and the vertex, we can plug in both to find a:

[tex]16=a(0-3)^2-2\\16=a(-3)^2-2\\16=9a-2\\18=9a\\2=a[/tex]

Thus, the equation is:

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount be = $ 375

Let the total number of bills = 24

Let the number of $ 5 bills be = x

Let the number of $ 10 bills be = y

Let the number of $ 20 bills be = z

The total number of $ 5 bills x = ( 1/2 ) x number of $ 10 bills

So , x = y/2

Now , the equation will be

The total number of bills = x + y + z

So , x + y + z = 24   be equation (1)

And ,

The total amount = 5x + 10y + 20z

So , 5x + 10y + 20z = 375

Divide by 5 on both sides , we get

x + 2y + 4z = 75   be equation (2)

On simplifying equation (1) and equation (2) , we get

x + y + z = 24

Substituting the value of y , we get

x + 2x + z = 24

3x + z = 24   be equation (3)

And ,

x + 2y + 4z = 75

x + 4x + 4z = 75

5x + 4z = 75   be equation (4)

Multiply equation (3) with 4 , we get

12x + 4z = 96   be equation (5)

Subtract equation (4) from equation (5) , we get

7x = 21

Divide by 7 on both sides , we get

x = 3

Therefore , the number of $ 5 bills is 3

Substitute the value of x , we get

y = 2x

y = 6

Therefore , the number of $ 10 bills is 6

Substitute the value for x and y in equation (1) , we get

x + y + z = 24

3 + 6 + z = 24

z + 9 = 24

Subtract 9 on both sides , we get

z = 15

Therefore , the number of $ 20 bills is 15

Hence ,

The number of $ 5 bills = 3

The number of $ 10 bills = 6

The number of $ 20 bills = 15
