Answer:
The x-intercepts of the graph of the function are -9 and 4
Step-by-step explanation:
- factor the function f(x)=x²+5x-36
- f(x)=(x+9)(x-4)
- x = -9, 4
(2/3)n - 6 = 2
Add 6 to both sides.
(2/3)n = 8
Divide by 2/3.
n = 9 / (2/3)
n = 27/2, or 13.5
810
all you need to do is plug in 12 for a and 7 for p. the you solve it.
8*12=96
7*4=28
96+28+11=135
6(135)=810
You can make this into an inequality, using x as the number of uniforms.
100 + 12x < 61 + 15x
39 < 3x
13 < x, so they must buy more than 13 to get a better deal.
