Answer:
a) y=8
b) x= 9
Step-by-step explanation:
a)
y/16= 2/4
y= 16 * 1/2 (cross multiply)
y= 8
b) x/5 = 36/20
x= 5 * 36/20 (cross multiply)
x= 9
Answer:
Step-by-step explanation:
Grace paid $4.80/(4 notebooks) = {$4.80/4)/notebook = $1.20 per notebook
Jim paid $3.90/(3 notebooks) = ($3.90/3)/notebook = $1.30 per notebook
Grace found the better buy.
The inverse of the function f(x) = 2x - 10 is f-1(x) would be x/2 + 5.
Lets try to solve it,
We will be using the inverse function to solve this.
f(x) =
Replace f(x) with y.

Interchange x and y

Solve for y

Replace y with f-1(x).

Thus, the inverse of the function f(x) = 2x - 10 is f-1(x) = x/2 + 5
