Answer:  a) 7

               b) c

<u>Step-by-step explanation:</u>

Inverse is when the x's and y's are swapped.

a)

f(7) = 22 means ..... when x = 7, then y = 22

The inverse is ..... when x = 22, then y = 7

b)

f⁻¹(f(c)) means ...... when x = f(c), then y = c

The reverse of the inverse is ..... when x = c, then y = f(c)

Ira used 1/2 a gallon of paint to 3/4 of his deck. How many gallons would it take to paint the entire deck?
lara31 [8.8K]

Answer:

2/3 gallons

Step-by-step explanation:

Given data

We have the following data

1/2 gallons is the same as 0.5 gallons

hence 0.5 gallons will cover 3/4 of his deck

           x gallons will cover 1 of his deck

cross multiply we have

3/4*x = 0.5*1 gallons

3x/4= 0.5

3x= 2

divide both sides by 3

x= 2/3

Hence 2/3 gallons will cover the entire deck
