Remember that the horizontal line test checks if a function is one-to-one. If a horizontal line passes through a graph more than once, the function has more than one x-value for at least one y-value.

PLEASE HELP!!!!!! I need help on this problem

Thepotemich [5.8K]

Answer:

185 minutes.

Step-by-step explanation:

It is possible to model an equation for this, such that

$0.10x + 14.80 = 0.08x + 18.50$

where x represents the number of minutes.

Then, you solve for x:

$0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x = \frac{3.70}{ 0.02} \\ x = 185$
