Answer:
b. 3/1 c. -1/3
Step-by-step explanation:
When a line is parallel to another they don't intersect and instead go in the same direction. Therefore they have the same slope
b. 3/1
When a line is perpendicular it has to be the negative reciprocal. This means that it you have to flip the numbers in the fraction and make it negative (unless it is already negative, then it becomes positive)
c. -1/3
so, the repairman charges $45 for each hour of work, and $44 for the parts, now the parts are obtained only once, so that's a one-time charge of 44 bucks, let's see how the hours go.
1 hour of work................... 45 + 44(1)
2 hours of work................45 + 44(2)
3 hours of work................45 + 44(3)
4 hours of work................45 + 44(4)
x hours of work................45 + 44(x)
so the cost equation, with x = hours, C(x) = 45 + 44x.
what is x if C(x) = 179?
