Exam Review

Front

What is the value of f(-8) if f(x) = 2x + 8?

Back

f(-8) = 2(-8) + 8 = -16 + 8 = -8.

Front

What value of p will satisfy the equation 2p + 4 = 24?

Back

p = 10.

Front

What are the x-intercept and y-intercept of the line represented by the equation 2x + 5y = 15?

Back

x-intercept: 7.5, y-intercept: 3.

Front

Evaluate the expression 6a x b + 2c for a = 3, b = 10, and c = 7.

Back

194.

Front

What is the solution set for the inequality -4x ≤ 6y - 54?

Back

The solution set is represented by the graph in option A.

Front

Define x-intercept.

Back

The x-intercept is the point where a line crosses the x-axis (y=0).

Front

Define y-intercept.

Back

The y-intercept is the point where a line crosses the y-axis (x=0).

Front

What is the slope of a line given two points (2, 3) and (4, 7)?

Back

Slope = (7 - 3) / (4 - 2) = 2.

Front

What is the formula for the slope-intercept form of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you solve the equation 3x - 5 = 16?

Back

Add 5 to both sides: 3x = 21; then divide by 3: x = 7.
