Answer:
[0,+♾)
Step-by-step explanation:
|x| function is kinda like a half opened book from (0, 0) and |x+5| is from (–5, 0)
So we can't find any changes for y
so the domain is
[0, +♾)
Answer:
The Answer is: The first number is 20 and the second number is -2.
Step-by-step explanation:
Let f = first number and s = second number.
The sum is 18:
f + s = 18
Solve for s:
s = 18 - f
The difference is 22:
f - s = 22
Substitute:
f - (18 - f) = 22
f - 18 + f = 22
2f = 22 + 18
2f = 40
f = 20, the first number.
Solve for s:
s = 18 - f
s = 18 - 20 = -2, the second number.
Proof:
20 + (-2) = 18
20 - 2 = 18
18 = 18
Then:
f - s = 22
20 - (-2) = 22
20 + 2 = 22
22 = 22
Hope this helps! Have an Awesome Day!! :-)
C. (2,1)
3(2)+7(1)=13
6+7=13
13=13
Well the answer is 300 hundred students because there is 36 that makes 12% then to find 100% you need to do 12/36= 100/x doing this given x = to 300 total
