Answer: X=4 and Y=3
Step-by-step explanation:
Answer:
s=32
Step-by-step explanation:

Divide both sides by -5
s-30=2
Add 30 to both sides

s=32
#of serverings: 1. 2. 3. 4. 5...
X: 4. 8. 12. 16. 20.
Y: 5. 10. 15. 20. 25.
The absolute value of 21 is 21 and the absolute value of -21 is also 21.
So its D
Set is a sum of two intervals :(1,4) u [2,6]
In the first interval it is open on both sides so 1 and 4 don't belong to this interval, the second is closed so both 2 and 6 belong to interval and numbers between 2 and 6
We can write it as 1<x

summing both sets we have one set: (1,6]
so
a) represent our set
b) also represent because all numbers between 4-6 and 6 are in our set
c)also represent, all numbers are in main set
d)also represent
