Answer:
Step-by-step explanation:
+x-20
use FOIL
(x - 4)(x+5)
x-4=0
x+5=0
4 and negative 5 are the factors
Let n = number of months both have their services
Provider A:
C = 35.50n + 55
Provider B:
B = 35.50n
Provider A will always cost more than
provider B because of the $55 installation fee
First convert 6 miles to yards. That would be 10,560 next divde it by 350 to get 30.1786 but you have to round it to the next lap. Therfore, youll have to run a total of 31 laps around the field.
Answer:
If the lines BC and DE are parallel, the value of c is c=-2
Step-by-step explanation:
We are given line segment BC with end points B(2, 2) and C(9,6) and line segment DE with endpoints D(c, -7) and E(5, -3).
Using slope formula:
we can find point c
When 2 lines are parallel there slope is same.
So, Slope of line BC =Slope of Line DE

We have:

Putting values and finding c

So, If the lines BC and DE are parallel, the value of c is c=-2
