Answer:

y = 1/3(x-5)

Step-by-step explanation:

To find the inverse of a function switch the x and y and then solve for y.

x = 3y + 5

x-5 = 3y

(x-5)/3 = y

Or

y = 1/3(x-5)

Answer:

The ratio of perimeter of ABCD to perimeter of WXYZ = \frac{2}{3}

Step-by-step explanation:

First, we have to determine the multiplicative factor of the dimensions for both figures.

Considering sides AB and WX,

multiplicative factor = \frac{12}{8}

                                = 1.5

So that:

XY = 6 x 1.5 = 9

YZ = 7 x 1.5 = 10.5

ZW = 7 x 1.5 = 10.5

Perimeter of ABCD = 6 + 7 + 7 + 8

                                = 28

Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12

                                 = 42

The ratio of the perimeters of the two quadrilaterals can be determined as;

ratio = \frac{perimeter of ABCD}{Perirmeter of WXYZ}

       = \frac{28}{42}

       = \frac{2}{3}

The ratio of the perimeter of ABCD to perimeter of WXYZ is \frac{2}{3}.

Each coach has 50 seats and there are 1030 supporters. How many coaches are needed to take all the supporters?
alisha [4.7K]
The answer would be to divide 1030 by 50 and you would get 21 coaches not 20 because 50x20=1000 and there are 30 remainder. Therefor, you would need that extra coach with some seats left to spare. so your answer is 21 coaches

B is the midpoint of AC. If AB= X +5 and BC = 2X -11, find the measure of AB
Murljashka [212]
First, you know that B is the mid point, meaning AB is equal to BC. Therefore, you can set up the equation: x+5=2x-11. Then, you solve for x. Once you are done solving, you should get 16. Hope this helps!

A scientist is interested in the effect of time spent with parents and number of hours
gladu [14]

Answer: If X = 5, z=<u>-3</u>

If X = 37, z= <u>3.4</u>

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

z=\dfrac{x-\mu}{\sigma}

, where \mu = Population mean

\sigma = Population standard deviation.

As per given , we have

\mu=20\\\\\sigma=5

Then , the z-score for x =5

z=\dfrac{5-20}{5}=\dfrac{-15}{5}=-3

i.e. If X = 5, z=<u>-3</u>

When x =37,then z=\dfrac{37-20}{5}=\dfrac{17}{5}=3.4

i.e. If X = 37, z= <u>3.4</u>
