Here are a few things you'll need to know for this question:
- Domain: <u>The list of x-values that are possible on a line.</u>
- Range: <u>The list of y-values that are possible on a line.</u>
- Interval Notation: <u>Shows the domain/range using the endpoints</u>. Brackets mean that the endpoint is included, parentheses mean the endpoint is excluded. Ex: (2,10]. 2 is excluded, 10 is included.
- Closed Circles: <u>The endpoint is included.</u>
- Open Circles: <u>The endpoint is excluded.</u>
So firstly, let's look at the domain. We see that there is a closed circle at x = -2 and an open circle at x = 5. Using what we know, <u>the interval notation of the domain is [-2,5).</u>
Next, let's look at the range. We see that there is a closed circle at y = -5 and an open circle at y = 2. Using what we know, <u>the interval notation of the range is [-5,2).</u>
Answer:
1 1/2
Step-by-step explanation:
Turn 8 1/4 into 33/4
Then multiply 33/4*2/11 to get 66/44 then simplify to 1 1/2
.5x=10+.25x
.25x=10
x=40
When you buy 40 songs
The cost equals 20$
C 1:3
15:45 can be simplified by dividing by 15 to give you a ratio of 1minute if commercials for every 3 minutes of the actual show
53×0.2 = 10.6
53×0.06= 3.18
53+3.18+10.6= 66.78
So the answer is $66.78 / number 2
