Answer:
- Domain:

- Range:
![(-5, 4]](https://tex.z-dn.net/?f=%28-5%2C%204%5D)
- Is the relation a function? - Yes
Step-by-step explanation:
The domain is the set of x-values and the range is the set of y-values.
A relation is a function if each value of x maps onto no more than one value of y.
Answer:
x = 11
Step-by-step explanation:
Since this is a triangle, all interior angles add up to 180 so:
57 + 73 + 3x + 17 = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11
Answer:
x= 1/8
Step-by-step explanation:
0.25r - 0.125 + 0.5r = 0.5 + r
0.75r - 0.125 = 0.5 + r |add 0.125 to both sides
0.75r = 0.625 + r |subtract r from both sides
-0.25r = 0.625 |divide both sides by (-0.25)
r = - 2.5
