What are the solutions to x² - 5x + 6 = 0?
Answer: x = 2 and x = 3
Factor as (x - 2)(x - 3) = 0, giving x = 2 and x = 3.
Simplify: (x² - 4)/(x + 2)
Answer: x - 2
Factor the numerator as (x + 2)(x - 2), then cancel (x + 2) to get x - 2.
Marcus earns $12 per hour plus a $25 bonus per day. Which equation shows his daily earnings E for h hours worked?
Answer: E = 12h + 25
Hourly pay is 12h and the flat bonus is 25, so E = 12h + 25.
What is the value of 5 × 10³ + 3 × 10² + 7 × 10⁰?
Answer: 5,307
5,000 + 300 + 7 = 5,307.
If the product of two consecutive even integers is 48, what are the integers?
Answer: 6 and 8
6 × 8 = 48, and 6 and 8 are consecutive even integers.
Which graph best represents the equation y = -x + 2?
Answer: A line with negative slope crossing y-axis at 2
The equation has slope -1 (negative) and y-intercept 2, so it falls left to right and crosses at (0, 2).
What is the solution to the inequality -3x + 6 < 15?
Answer: x > -3
-3x -3 (inequality flips when dividing by a negative number).
