9) A sweater costs $60 and is sold at a 20% discount. The store charged Aria $12. Is this correct? How do you know? Be clear and
complete.

No

Step-by-step explanation:

I know because if you take 20 percent of 60 you get 12.

60 × .20 = 12

But, that doesn't mean the sweater is $12, you only calculated the discount.

next, take 60-12= $48

She should've been charged $48

5x+10 is the correct one

hope this

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
