3x -5x + 8x = 4x + 18

x = 9

Step-by-step explanation:

3x - 5x + 8x = 4x + 18

combine like terms on the left side and you get 6x = 4x + 18

then you subtract 4x from both sides

you get 2x = 18

divide each side by 2 and you get x = 9

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
