Ariel is working at a meat- packing plant 5 nights a week. Her regular wage is $11 an hour. She earns time and a half for any overtime hours. This week she worked 9 hours of overtime. How much will Ariel earn for overtime this week?

She will earn $148.50 in overtime this week.

Step-by-step explanation:

First, you multiply 11 by 1.5. That gets you 16.5. So, for every overtime hour she works, she gets $16.50. Since she works 9 overtime hours, you multiply 16.5 by 9 to 148.5. So, she earns $148.50 for overtime this week.

The answer is : y = - 1x + 28

how I did it

(x-3)2+(y-9)2=16

1x - 3 times 2 + 1y -9 times 2 = 16

1x - 6 + 1y -18 =16
      +6        +6

1x + 1y -12 = 16
             +12    +12

1x + 1y = 28
 -1x                -1x

1y = -1x + 28
/1       /1      /1

y = - 1x + 28 or y = - x + 28
