Answer: =
Step-by-step explanation:
Answer:
27.5
Step-by-step explanation:
y = kx
55 = 120k
k = 55/120
y = 55/120 x 60
y = 55/2
y = 27.5
(-6,0) is a point of an x- intercept in this function
Answer:
At mile 3 company A will start charging less.
Step-by-step explanation:
I came to this conclusion by realizing that no matter what company A will always charge $107 so, in theory all we needed to do was get company eight to $108. So having this mind set I created the equation, 65 + .70x . I continuously kept on changing what was in x until the price was just above Company A's. And the number that got me there was 3.
Slope of AB
m = (y2 - y1)/(x2 - x1)
m = (11 - (-4))/(2 - (-1))
m = (11 + 4)/(2 + 1)
m = 15/3
m = 5
The slope of line AB is 5
Slope of CD
m = (y2 - y1)/(x2 - x1)
m = (10 - 1)/(4 - 1)
m = 9/3
m = 3
The slope of CD is 3
Since the two slopes are not equal, this means the lines are not parallel.
Since (slope of AB)*(slope of CD) = 5*3 = 15 is not equal to -1, this means the lines are not perpendicular
Answer: Neither (not parallel; not perpendicular)
