Solve the equation
4(2x-5)=7(2x+4)

• 8
• -8
• -1.5
• 1.5

Find the slope of the line containing these two points:
(-5, 1) and (-6, -3)

• m = 4/11
• m = 1/4
• m = -2
• m = 4

Which of the following solutions fits the graph shown?

• x < -2
• x > -2
• x ≤ -2
• x ≥ -2

-4x + 14 ≤ 54

• x ≥ - 10
• x ≤ -10
• x ≥ 10
• x ≤ 10

What is the equation in Point-Slope form

of the line that goes through

the point (6,1) and has a slope of -3?

• y - 6 = -3(x - 1)

• y + 6 = -3(x + 1)

• y - 1 = -3(x - 6)

• y + 1 = -3(x + 3)

April wants to prove that she can solve the system of equations below using the substitution method.
3x + y = 8
y = 4x - 6

Which equation shows the first step in solving the system of equations using the substitution method?

• 7x + 2y = 2
• -x +2y = 2
• 3x + (4x-6) = 8
• 3(4x-6) +y = 8

Select the piece of this equation I should DEFINITELY START solving FIRST: 4(x+5) = 15x + 5

• Distribute the 4 to the x and to the 5
• Divide both sides by 4
• Subtract 5 from both sides

Select the action I need to take next at this point in the solution: 4x +  6x =  8 + 2

• Combine like terms by adding 4x + 6x = 10 x
• Combine like terms by subtracting 2 from both sides
• Divide both sides by 4 and 6 

Find the zeros of this quadratic.

• b=4/5, b=3
• b=4, b=-3
• b=1/5, b=3
• b=4/5, b=-3
