Answer:
m=-1
Step-by-step explanation:
2x+3y=11............. (eqn 1)
2x-4y=-24...........(eqn 2)
Subtract eqn 1 from eqn 2
7y=35
y=5
Substitute for y in eqn 1
2x+3(5)=11
2x+15=11
2x=11-15
2x=-4
x=-2
y=mx+3
5=-2m+3
5-3=-2m
2=-2m
m=-1
Answer:
irrational
Step-by-step explanation:
irrational because there will still be a 2 under the root when you simplify to 2√2
This is the answer 2,043,000
Answer:
r = the square root of V/ pi*h
Step-by-step explanation:
You can find this by seperating r from the rest of the equation. You will have to divide V by pi and h, and then take the square root of it all, then r will be singled out on one side with the equation on the other. I added a picture so that it will be much more clear and simple.
