Answer:
x = 3
y = -1
Step-by-step explanation:
(x-y) + (x+y) = 4 + 2
2x = 6
x = 3
sub x=3 into x+y=2
3+y=2
y=2-3
y=-1
Check by subbing x=3 and y=-1 into x-y=4
(3)-(-1) = 3+1 = 4
Answer:
the answer is 11 1/2.
Step-by-step explanation:
I used a calculator
Answer:
16 pi cubic units
Step-by-step explanation:
Given that a region is bounded by

And the region is rotated about x axis.
We can find that here radius would be y value and height would be dx
So volume would be as follows:
If f(x) is rotated about x axis volume
= 
cubic units.
parallelogram formula is b*h because u can just move a part of the triangle to make it become a rectangle or square. so square/rectangle's formula is the exactly same.
