Answer:
Hence x = -1 and y = 18
<em></em>
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
Hence x = -1 and y = 18

5x - 4 = -3x + 12.
move -3x to the other side
sign changes to +3x
5x+3x-4= -3x+3x+12
5x+3x-4= 12
move -4 to the other side
sign changes to +4
5x+3x-4+4= 12+4
8x= 16
divide by 8 for both sides
8x/8= 16/8
x= 2
Answer: x= 2
To find the volume, you would use the formula V=1/3 pi times radius squared times the height. So, you would multiply 1/3 x 3.14 x 5.62^2 x 7.5. This equals approximately 248 cubic inches.
