An electrician charges a set fee for every house call and then charges an hourly rate depending on how long the job takes. Let C
C represent the total cost of the visit when the electrician spends
t
t hours at the house working. A graph of
C
C is shown below. Write an equation for
C
C then state the slope of the graph and determine its interpretation in the context of the problem.

Ineed with number 17 i don’t get it at alll

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 + 4x + 5 = 0
