-13+x=-25 what is the value of x
Ulleksa [173]

Answer:

\huge\boxed{-12}

Step-by-step explanation:

In order to find x with the equation -13 + x = -25, we can play with the equation until we have x isolated on one side of the equation.

Add 13 to both sides:

-13 + x + 13 = -25 + 13\\\\-13 + 13 = 0, -25 + 13 = -12\\\\x = -12

Hope this helped!

Consider the graph of f(x) given below.
tiny-mole [99]

The functions could represent g(x) is B. g(x) = f(x - 5)

<h3>How can the function be determined?</h3>

Using the general equation g(x) =f(x)+ b

The g(x) has intercept of y=-2,

Then the  y-intercept of f(x) is at y=3

If we find the difference between both y-intercepts, we have

( -2 -3) = -5

Then b=-5

Hence, g(x) = f(x - 5) is correct.
