y = 2 - 1
Step-by-step explanation:
y = 2 - 12x + 16
y = 2( - 6x + 8) ( Factor out 2 )
y + 9= 2( - 6x + 9) + 8 ( Complete the square ) Add 9 both sides
y + 9 = 2 + 8 (Subtract 9 each side)
y = 2 - 1 ( simplify )

Answer:
Step-by-step explanation:
6.5x + 14 = 2.25x - 20
4.25x + 14 = -20
4.25x = -34
x= -8
Answer: -8
Step-by-step explanation: 2.25x-20 = 6.5x +14
Subtract 14 on both sides and rearrange, 6.5x= 2.25x -34
then subtract 2.25x from both sides, 4.25x= -34
Finally divide both sides by 4.25 to get x = -8
Hope this helped!
