What is the value of x in the equation 2x + 5 = 17?
Answer: 6
2x + 5 = 17 → 2x = 12 → x = 6.
Which expression represents 'three times a number decreased by 7'?
Answer: 3n − 7
'Three times a number' is 3n, and 'decreased by 7' means subtract 7, giving 3n − 7.
If f(x) = 2x − 3, what is f(5)?
Answer: 7
f(5) = 2(5) − 3 = 10 − 3 = 7.
Which value of x satisfies 4x − 8 = 0?
Answer: 2
4x = 8 → x = 2.
What is the slope of the line passing through (0, 2) and (3, 8)?
Answer: 2
Slope = (8 − 2) / (3 − 0) = 6/3 = 2.
Which inequality is graphed as an open circle on a number line at 4 with an arrow pointing left?
Answer: x < 4
An open circle means the value is not included, and the arrow pointing left means x is less than 4.
