One minute is 1/60 of an hour. So 12 minutes would be 12/60 of an hour, or 1/5 of an hour reduced, and or .2 in decimal.

If you were to compress a function vertically by a factor of n, f(x) would change to 1/n * f(x). Thus, choice C is the correct answer.

How can you solve x-8y=40?

OLga [1]

$Simplifying
x + -8y = 40

Solving
x + -8y = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8y' to each side of the equation.
x + -8y + 8y = 40 + 8y

Combine like terms: -8y + 8y = 0
x + 0 = 40 + 8y
x = 40 + 8y

Simplifying
x = 40 + 8y$
