Answer:

x = 3

Step-by-step explanation:

Step 1: Write out equation

x + 9 = 18 - 2x

Step 2: Add 2x on both sides

x + 2x + 9 = 18 - 2x + 2x

3x + 9 = 18

Step 3: Subtract 9 on both sides

3x + 9 - 9 = 18 - 9

3x = 9

Step 4: Divide both sides by 3

3x/3 = 9/3

x = 3

If g(x) = a f(x + b), how is f(x) transformed to get g(x)?

nevsk [136]

Answer:

There was a Horizontal translation left b units and then Vertical stretch or compression

Step-by-step explanation:

Given : $g(x) = a f(x + b)$

We are supposed to show the transformation

Rule : f(x)→f(x+c)

Horizontal translation left c units

So, f(x+b) is the Horizontal translation left b units

Rule : f(x)→cf(x)

Vertical stretch or compression

So, $g(x) = a f(x + b)$

So, Initially there was a Horizontal translation left b units and then Vertical stretch or compression
