Answer:
All real numbers greater than or equal to -3
Step-by-step explanation:
First look at graph where the line points to which direction of the graph
And look for any closed or open circles in the graph
Since in the graph has a close circle at (-3,-2) meaning it includes that x-value for its domain.
With the graph going to positive infinity it states that the domain is all real numbers.
So in conclusion it has a domain of all real numbers greater than or equal to -3
Answer:
how many students are in the class
Step-by-step explanation:
A percentage is a way to describe a part of a whole. The percetage decrease in the price of CD is 33.33%.
<h3>What are Percentages?</h3>
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The price of the CD decreases from $18 to $12. Therefore, the percentage decrease is,
Percentage Decrease = ($18-$12)/$18 × 100% = 33.33%
Hence, the percetage decrease in the price of CD is 33.33%.

It would be less expensive if they are going for up to 7 months a year.
In order for those to be equal, they would need to go for 7.5 months. Since you can only round for months, I would say up to 7.
Equation: $100+$30x = $325.
