Question 1

A jacket originally costs $80 and is on sale for 25% off. What is the sale price?

Accepted Answer

$60

Answer

25% of $80 = $20 discount; $80 − $20 = $60 sale price.

Question 2

Which of the following ordered pairs is a solution to the equation y = 3x − 1?

Accepted Answer

(2, 5)

Answer

When x = 2: y = 3(2) − 1 = 5, so (2, 5) satisfies the equation.

Question 3

A right triangle has legs of length 6 and 8. What is the length of the hypotenuse?

Accepted Answer

10

Answer

By the Pythagorean theorem: c = √(6² + 8²) = √(36 + 64) = √100 = 10.

Question 4

Simplify: (2/3) ÷ (4/9)

Accepted Answer

3/2

Answer

Dividing by a fraction means multiplying by its reciprocal: (2/3) × (9/4) = 18/12 = 3/2.

Question 5

A linear function passes through (0, −2) and has slope 3. What is the equation of the line?

Accepted Answer

y = 3x − 2

Answer

Using slope-intercept form y = mx + b with m = 3 and b = −2: y = 3x − 2.
