### If I wanted to shift  two units to the right I would...

• A.

Change the x to (x-2)

• B.

Change the x to (x+2)

• C.

Add 2 to the end of the equation

• D.

Subtract 2 to the end of the equation

A. Change the x to (x-2)
Explanation
A right or left translation changes the exponent. The sign need to be a negative so x-2 would give me a +2 shift. An up or down translation is produced by adding or subtracting a number after the equation.

### Solving Equations: X+B = C Solve for x:x + 3 = -1

• A.

X = -5

• B.

X = -8

• C.

X = -4

• D.

X = 9

C. X = -4
Explanation
To solve the equation x + 3 = -1, we need to isolate x on one side of the equation. To do this, we can subtract 3 from both sides of the equation. This will give us x = -4 as the solution.

### Solving Equations: X+B = C Solve for x:x + 7 = 9

• A.

X = 1

• B.

X = 2

• C.

X = 3

• D.

X = 8

B. X = 2
Explanation
To solve the equation x + 7 = 9, we need to isolate the variable x. By subtracting 7 from both sides of the equation, we get x = 2. This is the correct answer because when we substitute x = 2 back into the original equation, we get 2 + 7 = 9, which is true.

### Solving Equations: AX = C Solve for x:8x = 4

• A.

X = 1/2

• B.

X = 0

• C.

X = 3/2

• D.

X = 3/8

A. X = 1/2
Explanation
To solve the equation 8x = 4, we need to isolate x. We can do this by dividing both sides of the equation by 8. This gives us x = 4/8, which simplifies to x = 1/2. Therefore, the correct answer is x = 1/2.

Rate this question:

• 6.

### Solving Equations: AX = C Solve for x:-6x = -2

• A.

X = -7/3

• B.

X = -5/2

• C.

X = 1/5

• D.

X = 1/3

D. X = 1/3
Explanation
The correct answer is x = 1/3 because when we divide both sides of the equation -6x = -2 by -6, we get x = 1/3.
