A plumber charges a flat fee of $71 to visit a home and examine a clogged drain. The plumber charges an additional $26 per hour spent foxing the drain. The total cost, C (in dollars), for fixing a drain that takes h hours is given by the following. C = 26h + 71

Answer the following
questions.

(a) What is the total cost for fixing a drain, that takes 6 hours?

(b) If the plumber charged a total of $357, how many hours did he spend fixing the drain?
hours=

A. 77+24(7)=$245

B. 12 hours.

Step-by-step explanation:

For b, what you need to do is minus 77 from 365. Then divided by 24.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
