Answer:
29
Step-by-step explanation:
To simply, follow the rules of PEMDAS (Parathensis,Exponents,Multiplication,Division,Addition and Subtraction). So, first do the problems in the parathesis, and to do that you must first do the exponent which is 8 squared, and the answer would be 64, next add 14 + 64 and that would be 78. Now that we are done with the paranthesis we should move on to the division which is 78 divided by 2 so that would be 39 next subtract 39 by 10 which would equal to 29, which is the answer
Answer:
The second option: The amount a customer pays increases $0.60 per mile driven.
Step-by-step explanation:
As seen on the graph, we are given the points (20,12) and (35,21).
This means that at 20mi driven, the amount paid is $12, and at 35mi driven, the amount is $21.
To find the rate of change we divide the distance driven by the cost to find the cost per mile:
20/12 = 0.6
35/21 = 0.6
The slope is 0.6, so it costs an extra $0.6 for every mi driven. Therefore it is the second option: The amount a customer pays increases $0.60 per mile driven.
Hope this helped!

Answer:
(7, 0).
Step-by-step explanation:
We have y = 3(x - 7)
y = 3x - 21
Point-slope form is
y - y1 = 3(x - x1)
y - y1 = 3x - 3x1
Comparing this to the equation y = 4x - 21 we see that y1 = 0 and x1 = 7.
