Algebra 1CP Fall Final Exam Review Part 1

Front

Solve for n: 2m - n = 8

Back

n = 2m - 8

Front

Identify the error in the equation: 19 - 2k = 3k - 1. The steps shown are: +3k, 19 + 1k = -1, -19, k = -20.

Back

Instead of adding 3k they should subtract 3k.

Front

Nancy purchased 4 apples and 6 bananas for $13 and 3 apples and 7 bananas for $13.50. Write the system of equations.

Back

4x + 6y = 13, 3x + 7y = 13.5

Front

Solve the inequality: -5|x - 4| > -20

Back

0 < x < 8

Front

Solve the system of equations by elimination: x + y = 5 and 2x + 3y = 12.

Back

x = 3, y = 2

Front

What is the definition of a variable in algebra?

Back

A symbol used to represent an unknown value.

Front

Define a linear equation.

Back

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

What is the slope-intercept form of a linear equation?

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

They have the same slope and will never intersect.

Front

What is the solution to the equation: 3x + 5 = 20?
