−6=b2

12

3

–3

–12

b = -3

Step-by-step explanation:

-6 = b2 is the same thing as -6 = 2b to be precise.  Divide 2 on both sides to get -3 as your b value.

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)  

47 - 90 = 43

43 - 180 = x

x = 137
