Find the percent of decrease if 110 is decreased to 88 A) 125% B)80% C)20%
stich3 [128]

Hey there! I'm happy to help!

We have 110 minus a certain percent of 110 equals 88. Let's call this percent p and solve.

110-110p=88

We subtract 110 from both sides.

-110p=-22

We divide both sides by 110.

p=0.2

Therefore, the percent decrease is C) 20%.

Have a wonderful day! :D

Which represents the inverse of the function f(x) = 4x?
Sidana [21]

Answer:

h(x) = x/4

Step-by-step explanation:

To find the inverse of a function, exchange x and y and then solve for y

y = 4x

Exchange x and y

x = 4y

Solve for y

Divide each side by 4

x/4 = 4y/4

y = x/4

The inverse  is

h(x) = x/4
