Answer:

$f^{-1}(x)=\frac{1}{4}x+3$

Step-by-step explanation:

We have been given the function $f(x)=4x-12$

Below are steps for finding the inverse of the function.

Step 1:

Replace f(x) with y

$y=4x-12$

Step 2:

Interchange x and y

$x=4y-12$

Step 3:

Solve for y

$x+12=4y\\\\y=\frac{1}{4}x+3$

Step 4:

Replace y with $f^{-1}(x)$

$f^{-1}(x)=\frac{1}{4}x+3$

Answer:

Q' (-2, 2)

P' (-2, 7)

R' (6, 2)

Step-by-step explanation:

When reflecting over a diagnal line such as y = x or y = -x, a trick is to count the boxes at an angle to see how many spaces it is away from the line. Be sure to recipicate what you counted the first time, and when reflecting over y = -x, flip the x and y coordinates and if needed, change the signs.

Hope this helps!

ELEN [110]

Answer:

$331.25

Step-by-step explanation:

Given:

The jewelry center bought a pair of earrings for $250

They are going to mark the price of the earrings up 32.5%

Question asked:

How much will they sell the earrings for ?

Solution:

Cost price of a pair of earrings = $250

Mark up value = 32.5% of $250

= $\frac{32.5}{100} \times 250\\\frac{8125}{100} = 81.25$

Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.

Selling price = cost price + mark up value

= 250 + 81.25

= $331.25

Thus, they sell the earrings for $331.25

Consider the ordered pairs (1,4), (-1,2), and (0,3). Which of the four equations below could have been used to generate these th

arlik [135]

Answer:

a. y = x + 3

Step-by-step explanation:

All three ordered pairs satisfy the first equation.

___

If you want to look into it a little further, you can notice that if you sort the ordered pairs by their x-values, you get ...

(-1, 2), (0, 3), (1, 4)

That is, the y-values increase (by 1) as the x-values increase (by 1).

All of the other answer choices have -1 as the coefficient for x, which means the y-values will decrease as x increases. None of these choices (b–d) is viable.
