Answer:
The discount is 30
169.99 is the price she will pay
Step-by-step explanation:
First find the discount
199.99 * 15%
199.99 * .15
29.9985
Rounds to 30.00
The discount is 30
199.99 - 30
169.99 is the price she will pay
Answer:
f(x) = -5/9 x + 5 1/9
Step-by-step explanation:
f(2)=4 and f(−7)=9 means the line pass through (2,4) and (- 7,9)
f(x) = mx + b
m = (y-y') / (x-x') = (9 - 4) / (- 7 - 2) = - 5/9
for (2,4) : b = f(x) - mx = y - mx = 4 - (- 5/9) x 2 = 4 + 10/9 = 46/9 = 5 1/9
f(x) = -5/9 x + 5 1/9
check for (-7, 9) f(-7) = (-5/9) * (-7) + 5 1/9 = 35/9 + 46/9 = 81/9 = 9
It's D. because you add the powers to get the solution. y x y + y x y = y x y x y x y = y^4
