Answer:
21x^2 - 23x - 20 = 0
Step-by-step explanation:
we conclude that for 500 miles, both plans will have the same cost.
<h3>
For how many miles both plans have the same cost?</h3>
Plan A charges a fixed amount of $75, plus $0.10 per mile, so if you drive x miles, the cost equation is:
A(x) = $75 + $0.10*x
For plan B we will have the similar equation:
B(x) = $100 + $0.05*x
The cost is the same in both plans when:
A(x) = B(x)
So we need to solve the linear equation:
$75 + $0.10*x = $100 + $0.05*x
$0.10*x - $0.05*x = $100 - $75
$0.05*x = $25
x = $25/$0.05 = 500
So we conclude that for 500 miles, both plans will have the same cost.

Answer:
Negative Slope.
-7/5
Step-by-step explanation:
Decreasing from left to right.
x = 3- -2 = 5
y = -2 - 5 = -7
y = -7/5x + 11/5
Well, 22 divided by 2 is 11, so 11$ per hour, 11 times 5 is 55, so 55 is your answer
