<h3>
Answer: 0.05x+10</h3>
Work Shown:
x = number of miles
Cost of company A = 0.09x+50.50
Cost of company B = 0.14x+60.50
Subtract the two expressions (B-A) to find the difference in price
B-A = (0.14x+60.50)-(0.09x+50.50)
B-A = 0.14x+60.50-0.09x-50.50
B-A = (0.14x-0.09x) + (60.50-50.50)
B-A = 0.05x+10

Answer:</h2>
Hence, the average rate of change in vertical height is:
-6
<h2>
Step-by-step explanation:</h2>
We know that the average amount that the roller coaster's height changes over each horizontal foot is basically the slope or the average rate of change of the height of the roller coaster to the horizontal distance.
i.e. it is the ratio of the vertical change i.e. the change in height of the roller coaster to the horizontal change.
Here the vertical change= -150 feet
and horizontal change = 25 feet
Hence,
Average rate of change is:
So, for every change in horizontal distance by 1 feet the vertical height drop by 6 feet.
12/x + 7 =13/x, where x is not 0;
<=> 12 + 7x = 13 <=> 7x = 1 <=> x = 1/7;
83 + 94 + 79 + 97 + 96 + 87 = 536.
536 ÷ 6 = 89.333333...
So, Lamonts' average is under 90.
