Answer:
2x + 5y = -15 OR 2x + 5y + 15 = 0 Not sure they want it equal to zero
Step-by-step explanation:
y + 7 = -2/5(x - 10)
y + 7 = -2/5 x + 4
2/5x + y =-3
5(2/5 x + y = - 3)
2x + 5y = - 15
OR
2x + 5y + 15 = 0

Explanation:
The amount that Frank paid on his last credit card bill shows how piecewise functions work.
Taking into account that:
- 1.5 percent = 1.5/100 = 0.015,
- 1 percent = 1 / 100 = 0.01, and
- 0.015 × 500 = 7.50,
You can model the amount paid using the piecewise function p(x):
Thus, your calculation is:
- p(x) = $7.50 + $ 0.01 × (741.23 - 500) = $ 9.91
