Solve for y: 4y - 3 = 2(y + 5)
Answer: y = 6.5
Distribute: 4y - 3 = 2y + 10. Subtract 2y: 2y - 3 = 10. Add 3: 2y = 13. Divide: y = 6.5.
Which value of x satisfies both x ≥ -2 and x < 5?
Answer: 3
The value 3 is in the interval [-2, 5). The value -3 is less than -2, 5 is not less than 5, and 7 is greater than 5.
What is the slope of the line represented by 3x + 6y = 18?
Answer: -1/2
Rewrite in slope-intercept form: 6y = -3x + 18, y = -1/2 x + 3. The slope is -1/2.
Solve: |2x - 6| = 10
Answer: x = 8 or x = -2
Set up two equations: 2x - 6 = 10 gives x = 8, and 2x - 6 = -10 gives x = -2.
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: -3x + 12 ≤ 0
Answer: x ≥ 4
Subtract 12: -3x ≤ -12. Divide by -3 and flip the inequality: x ≥ 4.
