The factor (x-9) is negative for x < 9. It is zero for x = 9.

The factor (7x+2) is negative for x < -2/7.

The factors have different signs for -2/7 < x < 9. When their signs are different, their ratio is less than zero. When x = 9, the ratio is equal to zero.

The appropriate choice is the graph that shows -2/7 < x ≤ 9.

What is the sales tax rate?

Allisa [31]

Hello there! We are solving for the tax rate, so let's start off by subtracting both prices. 4.32 - 4.00 is 0.32. That's a 32 cent difference in the price. Now, let's divide that number by the original price to find the percentage. 0.32/4 is 0.08. Multiply that number by 100 and that is 8%. There. The sales tax rate is 8%.
