Answer: 31.25
Explanation: 6.25 x5 = 31.25 kilometers
They build 31.25 kilometers of road
Answer:
9
Step-by-step explanation:
<span>x + 9 = 2(x - 1)^2
x + 9 = 2(x^2 - 2x + 1)
x + 9 = 2x^2 - 4x + 2
</span>2x^2 - 4x + 2 - x - 9 = 0
2x^2 - 5x -7 =0
First, find the slope of the line contains the points (1,-6) and (-2,6) using slope formula
m =

plug in the numbers
m =

m =

m =

m = -4
Second, determine the slope of perpendicular line
The slope of the perpendicular line is the opposite and reciprocal from the other line. Thus, the slope is
