If x=5 and y= -4, evaluate this expression: (-2x +10) - (-6x + 5y + 12) + (x +8y - 16)

The value of the expression is - 5.

Step-by-step explanation:

(-2x +10) - (-6x + 5y + 12) + (x +8y - 16)=

-2x+10+6x-5y-12+x+8y-16=

(-2x+6x+x)+(-5y+8y)+(10-12-16)=

5x+3y-18

if x=5 and y=-4 then

5*5+3*(-4)-18=25-12-18=25-30=-5

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
