CA Equations Review PART 1

Front

What does the inequality 15 + 6x ≤ 100 represent in a real-world scenario?

Back

It represents a situation where Lazer Zone charges $15 plus $6 per person, and Andrea has a maximum of $100 to spend on inviting people to play laser tag.

Front

How do you calculate the time it takes for a plant to grow from 5cm to 23cm at a rate of 3cm per month?

Back

You can set up the equation: 5 + 3x = 23, where x is the number of months. Solving gives x = 6 months.

Front

What is the term used to describe the rate of change in a linear equation?

Back

Slope.

Front

Write the equation that represents Penelope's total spending at the carnival if she spends $35 in total.

Back

.50x + 20 = 35, where x is the number of ride tickets.

Front

If Bob has $150 and saves $40 per month, what equation represents his savings when he has saved $400?

Back

400 = 150 + 40x, where x is the number of months.

Front

What is the definition of slope in the context of a linear equation?

Back

Slope is the measure of the steepness of a line, representing the rate of change of the dependent variable with respect to the independent variable.

Front

How do you determine the maximum number of people Andrea can invite to Lazer Zone?

Back

By solving the inequality 15 + 6x ≤ 100 for x.

Front

What is the initial height of the plant before it starts growing?

Back

5 cm.

Front

If a ride ticket costs $0.50, how much would it cost for 10 tickets?

Back

$5.00.

Front

What is the total cost for Penelope if she buys 30 ride tickets?

Back

$20 (entrance) + $15 (30 tickets) = $35.
