WILL MARK BRAINLIEST IF YOU GET IT RIGHT.

A B and D

Step-by-step explanation:

these numbers could represent percents like 95% off 85% off or 55% off

so if n represents 1 item you would do 0.95(1) which equals 0.95 off of the original price which would make it 0.05

hope this makes sense

b

step-by-step explanation:

the word superfluous means unnecessary

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)
