Answer:

Below in bold.

Step-by-step explanation:

-6x + 3y = -7

The x intercepts occur when y = 0, so

-6x + 3(o) = -7

x = -7/-6

x = 7/6

So the x-intercept =  (7/6, 0).

The y intercept:

-6(0)  + 3y = -7

y = -7/3.

So the y-intercept =  (0, -7/3.t).

Answer:

14/9

Step-by-step explanation:

(1+1/3)^2 −2/9

Add the terms in the parentheses

(3/3+1/3)^2 −2/9

(4/3)^2 −2/9

Exponents

16/9 - 2/9

14/9

For this problem, PEMDAS is really important, because we need to make sure that we are doing things in the correct order.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

The first thing we need to do is the math inside the parentheses:

(1 + 1/3) = 1 + 1/3 = 4/3

Next, we square the parentheses:

(4/3)² = 16/9

Now, all we need to do is subtract!

16/9 - 2/9 = 14/9

If you need to make it a proper fraction, your answer is 1 5/9, but if you leave it improper then 14/9.

Answer:

x-y is parallel, im confused on what your asking for and what you mean by "negative"

Step-by-step explanation:

The  equation of a line that is perpendicular to line g that contains (P, Q). is 3x − y = 3P − Q

The general form of the equation of a line with a slope m and passing through the point (x1, y1) is given as: y - y1 = m ( x- x1)

Further, this equation can be solved and simplified into the standard form of the equation of a line.

Given:

Line g passes through (3,6) and (0,5).

Slope of lone= y2 - y1/ (x2 - x1)

Perpendicular lines have opposite, reciprocal slopes, so negative change in x over change in y.

slope of line= -(-3 - 0)/(6 - 5)

                      = - -(-3)/1 =

slope of line = 3

Now, Two lines are perpendicular if they have the same slope.

Line parallel to line g has a slope of 1. Since it passes through (P, Q),

y - y1 = m ( x- x1)

y- Q =3 ( x- P)

y- Q = 3x- 3P

3x − y = 3P − Q

Answer:

  x = -2

Step-by-step explanation:

Collect terms:

  26 = -13x

Divide both sides of the equation by the coefficient of x:

  26/-13 = x = -2

The solution is x = -2.

Answer:

-2

Step-by-step explanation:

14+12=-15x+2x

26=-13x

x=26/-13

x=-2

Answer:

No solution.

Step-by-step explanation:

Distribute.

-3(2x + 1) = 2(-3x - 1)

-6x - 3 = -6x - 2

Combine like terms.

-6x - 3 = -6x - 2 add 3 to both sides

-6x = -6x + 1 add 6x to both sides

0 = 1 this is false.

Because we ended up with a false equation, there is no solution to this equation.

Answer:

no solution

Step-by-step explanation:

Perform the indicated multiplication, using the distributive property.

-3(2x+1)=2(-3x-1)  becomes -6x - 3 = -6x - 2

This has no solution because -3 is never equal to -2.

Step-by-step explanation:

Answer:

Area: [tex]50\pi -100[/tex]

Perimeter: 20[tex]\pi[/tex]

Step-by-step explanation:

If we take half of one of these "pedals" we can see that it is simply 1/4 of a circle with radius 5, subtracted by a triangle. Let's calculate this half-pedal.

[tex]1/4(25 \pi) - 1/2(5* 5)[/tex]

That means 4 pedals is equal to:

[tex]8(1/4(25\pi) - 1/2 (25))[/tex]

[tex]50\pi - 100[/tex]

So.. The area of the shaded region is [tex]50\pi -100[/tex]

Perimeter is even simpler. the half-pedal is just 1/4 of the circumference of the circle. The circumference is just [tex]10\pi[/tex], which means our half pedal is:

[tex]1/4(10\pi )[/tex]

Multiplying by 8, our perimeter is just 20[tex]\pi[/tex].

Answer:

Normal; increases.

Step-by-step explanation:

In Statistics and probability, a student t-distribution also known as the t-distribution refers to the continuous probability distribution which can be used to estimate population parameters when the population variance or standard deviation is not known (unknown) and the sample population is relatively small. The student t-distribution is a statistical distribution which was published in 1908 by William Sealy Gosset.

The t-distribution approaches the normal distribution as the sample size increases because the parameters becomes negligibly smaller.

This ultimately implies that, when the degree of freedom of a t-distribution curve is increased in comparison with that of a normal distribution, the value of probability becomes significantly similar.

Answer:

You can check if an equation is true for all some or no values of x by simply to  try and solve the equation if you get something like x = x, then the equation  is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

Answer:

6/11,  20/33,  2/3,  25/33  (answers vary)

Step-by-step explanation:

First, we need to convert both of these fractions to the same denominator. To do that, we need to find the least common denominator for both fractions.

6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72

11: 11, 22, 33, 44, 55, 66, 77

The LCM of 6 and 11 is 66. (6 * 11 = 66)

Now, we multiply 5/6 by 11/11 and 5/11 by 6/6.

[tex]\frac{5}{6} *\frac{11}{11}=\frac{55}{66}\\\\\\\frac{5}{11} *\frac{6}{6} =\frac{30}{66}[/tex]

Now, we can just choose four numbers between 30 and 55 and get our answer (remember to simplify!).

[tex]\frac{36}{66} =\frac{6}{11}[/tex]

[tex]\frac{40}{66}=\frac{20}{33}[/tex]

[tex]\frac{44}{66} =\frac{2}{3}[/tex]

[tex]\frac{50}{66} =\frac{25}{33}[/tex]

Answer:

Step-by-step explanation:

The rate at which distance is increasing between the birds is ...

  r = d/t = (402 mi)/(6 h) = 67 mi/h

This is the sum of the speeds of the two birds, so is 15 mph more than double the speed of the slower bird. That bird's speed is then ...

  (67 -15)/2 = 26 . . . miles per hour

The faster bird is 15 mph faster so is 26+15 = 41 mph.

The slower bird's speed is 26 mph; the faster bird's speed is 41 mph.

Answer:

40%

Step-by-step explanation:

The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.

Set up a fraction:

[tex]\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}[/tex]

Convert into a decimal:

[tex]\frac{2}{5}= 0.4[/tex]

Multiply the decimal by 100 to get the percent:

[tex]0.4*100=40[/tex]

So, forty percent of the rectangle is shaded.

Hope this helps.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The percentage of the shaded rectangular boxes in the large rectangle is 40%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of rectangular boxes in the large rectangle = 5

Number of shaded rectangular boxes in the large rectangle = 2

The percentage of shaded rectangular boxes.

= 2/5 x 100

= 2 x 20

= 40%

Thus,

The percentage of the shaded rectangular boxes in the large rectangle is 40%.

If we have 10 to a positive number, that many times the decimal place will move to the right. It's the opposite for 10 to the power of a negative number.
