Solve: 3x/4 - 2 = 7
Answer: x = 12
3x/4 = 9. 3x = 36. x = 12.
Find f(−3) if f(x) = x² + 2x − 1.
Answer: 2
f(−3) = 9 − 6 − 1 = 2.
If 4x + 3y = 24 and y = 4, what is x?
Answer: x = 3
4x + 12 = 24. 4x = 12. x = 3.
What is the slope of the line through points (2, 5) and (6, 13)?
Answer: m = 2
slope = (13−5)/(6−2) = 8/4 = 2.
Solve the inequality: 3x − 5 > 10
Answer: x > 5
3x > 15. x > 5.
Resistance in a circuit follows R = ρL/A. If ρ = 0.02, L = 100, and A = 0.5, what is R?
Answer: 4 ohms
R = 0.02 × 100 / 0.5 = 2 / 0.5 = 4 ohms.
