Answer:
<u>Step-by-step explanation:</u>
Use the equation y = mx + b
- y: total bill
- m: rate (fee per mile)
- x: number of miles
- b: flat rate
60 = 3x + 14
46 = 3x
A: 39 over 50000
b: 20003 over 10000
Answer: A=-2
Step-by-step explanation:
AB=11
B=9
B-11=A
9-11=A
A=-2
y = (x+2)(x-6)(x+7)
<span>(x+2)(x+7)
x^2 - 6x + 2x - 12
x^2 - 4x - 12</span>
<span /><span>(x^2 - 4x - 12)(x + 7)
x^3 + 7x^2 - 4x^2 - 28x - 12x - 84
x^3 + 3x^2 - 40x - 84</span>
<span /><span>y = x^3 + 3x^2 - 40x - 84
</span>
