Mrs. Bailey gives a test, and her students’ scores range from 30 to 70. She decides to curve the scores, so that they range from
Harman [31]

Answer:

f(x) = x*3/4 + 42.5

Step-by-step explanation:

The original difference between the pair is 70 - 30 = 40

The new difference between the pair is 95 - 65 = 30

Since the differences are not the same, Mrs Bailey must first perform a (slope) multiplication by a factor of 30/40 or 3/4

Then 30 * 3/4 = 22.5

Then she can shift the scores up by 65 - 22.5 = 42.5 in order to get the range from 65 to 95

Therefore, f(x) = x*3/4 + 42.5. We can test that

f(30) = 30*3/4 + 42.5 = 65

f(70) = 70*3/4 + 42.5 = 95

Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the tabl
MakcuM [25]

The equation for the direct variation is y= kx (where k is contant of variation.)

This equation represent that if x will increase then y will also increase because it's k times x.

Where the equation for indirect variation is y=\frac{1}{k} x

By this equation if x will increase then y will decrease and vice versa.

The given data is :

x: 2 4 8 12

y: 4 2 1 2/3

Notice as x is increasing then y is decreasing. Like x has increased from 2 to 4 then y is decresing from 4 to 2 and so on.

So, the given data represent an indirect variation.

13 POINTS PLEASE HELP ME!!!
Natasha_Volkova [10]

First problem:

n/4 + 2 = -9

        -2      -2

n/4 = -11

x4       x4

n = -44

Check:

-44/4 + 2 = -9

-11 + 2 = -9

-9 = -9

Second problem:

3/4x = -12

0.75x = -12

--------     ----

0.75       0.75

x = -16

3/4 * (-16) = -12 OR 0.75 * (-16) = -12

-12 = -12

Still get the same answer.
