A computer repair technician charges $35 for each job plus $21 per hour of labor and 110% of the cost of parts. The total charge

Novay_Z [31]

Answer:

The cost of parts was $65.

Step-by-step explanation:

Let the cost of parts = x

35 + 21(3) + 1.10x = 169.50

98 + 1.10x = 169.50

71.50 = 1.10x

71.50/1.10 = 65

If f(7)=22, then f-1(22)=

nignag [31]

Answer:

$f^{-1}$ (22) = 7

Step-by-step explanation:

The inverse function maps the output of the function back to its input

f(7) = 22 means when input is 7 the output is 22

The inverse maps the output 22 back to the input 7 , that is

$f^{-1}$ (22) = 7

X-4y=7 -6x-3y=12 how do i solve by substitution

Dafna1 [17]

Answer:

x = 15

y = 2

Step-by-step explanation:

X-4y=7 | ×6 |

-6x-3y=12 | ×1 |

6x - 24y = 42

-6x - 3y = 12

___________+

27y = 54

y = 54/27

y = 2

x - 4y = 7

x - 4(2) = 7

x - 8 = 7

x = 7 + 8

x = 15
