Solve for x: 3(x - 4) = 2x + 5.
Answer: 17
Distribute to get 3x - 12 = 2x + 5, then x = 17.
What is the slope of the line passing through (2, 3) and (6, 11)?
Answer: 2
Slope = (11 - 3)/(6 - 2) = 8/4 = 2.
Factor completely: x² - 9.
Answer: (x - 3)(x + 3)
x² - 9 is a difference of squares equal to (x - 3)(x + 3).
If f(x) = 2x² - 3x + 1, what is f(2)?
Answer: 3
f(2) = 2(4) - 3(2) + 1 = 8 - 6 + 1 = 3.
Solve the inequality: 4x - 7 > 9.
Answer: x > 4
Add 7 then divide by 4 to get x > 4.
Which expression is equivalent to 5(2x + 3) - 4x?
Answer: 6x + 15
Distribute to 10x + 15 - 4x, which simplifies to 6x + 15.
What are the solutions to x² - 5x + 6 = 0?
Answer: x = 2 and x = 3
It factors as (x - 2)(x - 3) = 0, so x = 2 or x = 3.
