So for this, we will be using elimination method. With these two equations, subtract (x - y = -3) from (x + 3y = 5) to get . From here we can solve for y.
For this, just divide both sides by 4, and your answer will be
Now that we have the value of y, substitute it in into either equation to solve for x:
In short, <u>x = -1.</u>
Answer:
The volume of the prism is
Step-by-step explanation:
we know that
The volume of the prism is given by the formula
----> equation A
The volume of the cylinder is given by the formula
---> equation B
Remember that
If the height is the same and their cross-sectional areas are equal at every level parallel to their respective bases, then their volumes are equal
so
Find the volume of the cylinder
substitute the given values
therefore
The volume of the prism is
