PERT practice THREE

Front

Solve for x: 3x + 10 = 12

Back

x = 0.67

Front

Evaluate (b² - 2)² if b = 3

Back

(3² - 2)² = 49

Front

Solve for x: 2(3x + 4) + 2 = 1 - 3x

Back

x = -1

Front

Simplify: (x - 2)²

Back

x² - 4x + 4

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / 2a

Front

Define a linear equation.

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What is the slope-intercept form of a line?

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What is the difference between an expression and an equation?

Back

An expression is a combination of numbers and variables without an equality sign, while an equation states that two expressions are equal.

Front

Solve for x: 5x - 3 = 2x + 9

Back

x = 4
