Hello,
2x-5y=1 |3|4
3x-4y=-2|-2|-5
------------------------
-7y=7 ==>y=-1
-7x=14==>x=-2
sol={(-2,-1)}
I'm going to suppose that this is asking for the volume.
The formula to find volume for a cylinder is<span> V= pi r 2(squared) h
</span><span><span />The radius is 10cm and the height is 14cm
Then plug the numbers in
So you should get V=3.14 x 10(squared) x 14
The once you multiply all that you should get 4396 cm(cubed)
</span>
Answer:
True
Step-by-step explanation:
Answer:
1-22:2
2-33:3
3-44:4
Step-by-step explanation:
11+11=22
22+11=33
33+11=44
1+1=2
2+1=3
3+1=4
so, 22:2
33:3
44:4
Always, ALWAYS remeber this format: y = mx + b
In this equation, 'm' is the slope, and 'b' is the y-intercept
When you're trying to find a slope, remember that the equation is 
When finding the rise and run, look at two points that are on the graph AND on the line as well. Essentially, make sure the points you're using are integers.
In this, case, the rise is -3, and the run is 2. This means that the slope is 
Now we have the first part of our equation:
y = -
+ b
But wait! How do we find b?
Sometimes you have to input x in order to find it, but only when you're not supplied with a graph. In this case, all you have to do is look!
The point of the line that is on the y-axis is called the y-intercept.
In this graph, the y-intercept is -1
Now we have our complete equation!
y = -
- 1
Good luck!
