An electrician charges $20 for a service call plus $40 per hour of service. Write an equation in slope-intercept form for the cost, C, after h hours of service. What will be the total cost for 8 hours of work? 10 hours of work?

Step-by-step explanation:

Regular charge- $20                                      

Every hour of service cost- $40

Equation or slope intercept form-

C= 40h+20

Part 1-  20+40(8)=

40 multiplied by 8                320+20         = $340

Part 2-  20+40(10)=

40 multiplied by 10             400+20           = $420

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

(x, y)→(x − 8, y − 7)
