The difference between half a number and 11 is -25

1/2n - 11 = -25

Hope this helps you! Have a good night!

Also, n = -28

1/2n - 11 = -25

1/2n - 11 + 11 = -25 + 11

1/2n = -14

1/2n / 1/2 = -14 / 1/2

n = -28

Check:

1/2(-28) - 11 = -25

-14 - 11 = -25

-25 = -25

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)
