The answer to the question
Just take 78 and divide by 3, he gets 26 mpg with his car.
Answer:
x=5
Step-by-step explanation:
You are given two points on the line:
.. (1, 7) and (4, 5.5)
You can use the 2-point form of the equation for a line.
.. y = (y2-y1)/(x2-x1)*(x -x1) +y1
.. y = (5.5 -7)/(4 -1)*(x -1) +7
.. y = -0.5x +7.5
Your linear equation is y = -0.5x +7.5
The first one is n^2 +34
The second one is 5 x 2n. Hope this helps
