Algebraic expressions question a company charges $59.99 for cable tv installation and $49.99 per month for basic cable service. part a write an algebraic expression to represent the total cost of m months of basic cable service, including installation. algebraic expression:part b how much will it cost for installation and one year of basic cable service? explain: total cost:this problem is continued on the next page. part c after the first 12 months, the charge will be increased to $69.95 per month. what is the total cost of installation and basic cable service for the first two years? explain:

Part A.

We can create a linear equation from this problem. Let us say that C is total cost and m is number of months, therefore:

C = 59.99 + 49.99 m

Part B. For m = 12 months, the total cost is:

C = 59.99 + 49.99 * 12

C = $659.87

Part C. We have already calculated in part B the total cost for the 1st year:

C1 = $659.87

For the 2nd year, the equation becomes:

C = 59.99 + 69.95 m

C = 59.99 + 69.95 * 12

C2 = $899.39

Therefore the total cost C1 + C2 is:

$1,559.26

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
