(10th) Spiral Review #1

Simplify the expression:

3x + 4y - 5x + 7y

• -2x + 11y

• 8x - 11y

• -2x - 3y

• 9xy

Solve for x.

2x - 6 = 12

• x = 9

• x = 8

• x = 11

• x = 7

What is the slope of the graph?

What is the slope of the line?

• Zero

• Positive

• Negative

• Undefined

Solve for x.

4x + 15 = 2x + 45

• x = 15

• x = 20

• x = 25

• x = 12

Determine the number of solutions to the equation:

2x - 5 = 2x - 5

• Infinitely Many Solutions

• No Solution

• One Solution

Simplify the expression:

3(2x + 4) + 4x

• 10x + 12

• 10x + 16

• 2x + 12

• 2x + 4
