Answer: the monthly rate for the cell phone plan is $45

Step-by-step explanation:

Let m represent the monthly rate that the cellphone company charges.

A cell phone company charges $60 for a cell phone and a monthly rate to use the phone. This means that the total charge for using the phone for x months would be

60 + xm

If Regina will pay $1140 for a 24 month cell phone plan, it means that

1140 = 60 + 24m

24m = 1140 - 60

24m = 1080

m = 1080/24 = 45

**Answer:**

The answer to your question is: (1/2, 5)

**Step-by-step explanation:**

Parabola f(x) = 8x² - 8x + 7

y = 8x² - 8x + 7

Vertical Parabola equation

( x - h)² = 4p (y - k) **Transform the original equation to this form**

8x² - 8x = y - 7

8(x² - x + ( )²) = y - 7 **Complete squares**

8 (x² - x + (1/2)²) = y - 7 + 2 **Simplification**

8 (x² - x + 1/4) = y - 5

(x - 1/2)² = 1/8 (y - 5)

**Finally Vertex**

(1/2 , 5)

So if we want to make sure y x 15 is less than 180, we can plug in low values and check the inequality.

If we plug in 0, we get 180 > 0 which is true.

If we plug in 1, we get 180 > 15 which is true.

If we plug in 2, we get 180 > 30 which is true.

Therefore, 3 values that satisfy the inequality are 0, 1, and 2.
