Answer:
Domain: 
Range: ![[0,4]](https://tex.z-dn.net/?f=%5B0%2C4%5D)
Step-by-step explanation:
<u>Domain</u>
We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write . Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.
<u>Range</u>
Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be .
Do you want a ratio? If yes, the ratio is 120:52
First you make -1 and 3/4 have a common denominator. 1 has a fraction of 1/1 so times four it is 4/4. Then you add on both sides in order to isolate x and you get 3/10x = 7/4.
Then you isolate x by multyiplying the reciprocal of 3/10 on both sides, 10/3.
3/10 and 10/3 cancel out and you get an answer of x = 70/4.
You could then simplify it to get 35/6 by finding a greasted common multiple of 12 and 70 which is 2 and dividing both by 2 to get a simpilier answer.
So the answer is x = 35/6
Answer:
3.50
Step-by-step explanation:
First we take the 500 fee for purchasing pencils off of the total:
4700-500 = 4200
This means we pay 4200 for 1200 pencils; dividing this will tell us the amount per pencil, x:
4200/1200 = 42/12 = 21/6 = 7/2 = 3.5
Thus we pay 3.50 per pencil.
