Solve for x: 5x − 3 = 2x + 9
Answer: x = 4
Subtract 2x from both sides to get 3x − 3 = 9, then add 3 and divide by 3 to find x = 4.
Which scatterplot description indicates a strong negative correlation?
Answer: Points cluster tightly along a line sloping downward
A strong negative correlation means data points fall close to a downward-sloping line.
What is the slope of the line passing through (2, 3) and (6, 11)?
Answer: 2
Slope = (11 − 3) ÷ (6 − 2) = 8 ÷ 4 = 2.
Which inequality is represented by the statement 'twice a number is at most 14'?
Answer: 2n ≤ 14
'At most 14' means less than or equal to 14, so the inequality is 2n ≤ 14.
A survey of 200 students found that 60 prefer math. What percentage prefer math?
Answer: 30%
(60 ÷ 200) × 100 = 30%.
Simplify: (x³ · x²) ÷ x⁴
Answer: x
Multiply exponents in the numerator: x³ · x² = x⁵, then x⁵ ÷ x⁴ = x¹ = x.
