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
Correct Answer
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.Rate this question:

Solving Equations: X+B = C Solve for x:x + 3 = -1
- A.
X = -5
- B.
X = -8
- C.
X = -4
- D.
X = 9
Correct Answer
C. X = -4Explanation
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.Rate this question:

Solving Equations: X+B = C Solve for x:x + 7 = 9
- A.
X = 1
- B.
X = 2
- C.
X = 3
- D.
X = 8
Correct Answer
B. X = 2Explanation
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.Rate this question:

Solving Equations: AX = C Solve for x:8x = 4
- A.
X = 1/2
- B.
X = 0
- C.
X = 3/2
- D.
X = 3/8
Correct Answer
A. X = 1/2Explanation
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:

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
Correct Answer
D. X = 1/3Explanation
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.Rate this question:
