A computer technician charges a flat base fee plus an hourly rate for all repairs. Last year, she used the formula y = 18 x + 22 to determine the cost in dollars, y, of a repair that required x hours of work. If she doubles her base fee this year, what equation should she use to determine the new cost of an x-hour repair? y = 18 x + 44
y = 36 x + 22
y = 36 x + 44
2 y = 18 x + 22 HELP ASAP

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
