Semester 1 Final Review

Front

What is the function rule for a linear relationship where the output increases by 5 for every increase of 1 in the input, starting from 1?

Back

y = 5x + 1

Front

What is the Subtraction Property of Equality?

Back

If you subtract the same number from both sides of an equation, the two sides remain equal.

Front

What is the Division Property of Equality?

Back

If you divide both sides of an equation by the same non-zero number, the two sides remain equal.

Front

Write the function rule for the total rental cost of a car with GPS installed for x days, given a base charge of $28 and an additional $8 per day.

Back

y = 8x + 28

Front

Evaluate the function f(x) = 2x + 3 when x = -4.

Back

-5

Front

What is the definition of a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input.

Front

How do you solve the inequality -83 < n - 80?

Back

Add 80 to both sides to get n > -3.

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line, represented by the equation y = mx + b.

Front

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

Back

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