X/2 + 15 = x/8 + 12 im about to be out of points whoops

x=−8

Step-by-step explanation:

Let's solve your equation step-by-step.

x2+15=x8+12

Step 1: Simplify both sides of the equation.

12x+15=18x+12

Step 2: Subtract 1/8x from both sides.

12x+15−18x=18x+12−18x

38x+15=12

Step 3: Subtract 15 from both sides.

38x+15−15=12−15

38x=−3

Step 4: Multiply both sides by 8/3.

(83)*(38x)=(83)*(−3)

x=−8

x=−8

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)  

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
