What is x in this equation?

2x = 20

x=10

Step-by-step explanation:

2x=20

2x10=20

Therefore x=10

Its answer is 10.

Step-by-step explanation:

2x=20

x=20/2

x=10

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
