Answer:
The difference in per-mile costs for the two companies is $0.12
Step-by-step explanation:
Gabi sets up the equation
to find out after how many miles, m, the companies will charge the same amount.
The first company charges
for m miles driven.
The second company charges
for m miles driven.
In both these functions, numbers 7.20 and 8,40 represent the initial fee the companies charge.
Numbers 0.22 and 0.1 represent per-mile costs.
Thus, the difference in per-mile costs is 
Another way to solve this problem is to find the cost per mile driven for each company:
1. Cost per-mile 1st company

2. Cost per-mile 2nd company

3. Difference:

Answer:
<h2>
(1, 41)</h2>
Step-by-step explanation:
h = 1
k = p(h) = 4·1² + 24·1 + 13 = 4 + 24 + 13 = 41
Answer:
y = (4/7)x² - (24/7)(x)
Step-by-step explanation:
4 = a(-1)² + b(-1)
4 = a - b
0 = a(6)² + b(6)
36a + 6b = 0
b = -6a
4 = a - (-6a)
7a = 4
a = 4/7
b = -24/7
y = (4/7)x² - (24/7)(x)
