Carol's phone service charges $14.65 for an activation fee plus $2 for every gigabyte (g) used.

Carol's phone price is

Step-by-step explanation:

We are given

Carol's Phone Service charges $14.65

so, fixed price is $14.65

Let's assume total number of gigabytes used as g

Total price = fixed price + ( total number of gigabytes)*(activation fee charges)

we can plug values

and we get

answer: x=3 and y=4

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
