y=-8x
To find x-intercept/zero, substitute y=0
0=-8x
solve the equation for x
x=0
now we do the same only different way ok
0=-8x
swap the sides of the equation
-8x=0
divide both sides of the equation by -8
x=0

Answer:
1) ![B=15in^{2},h=17in](https://tex.z-dn.net/?f=B%3D15in%5E%7B2%7D%2Ch%3D17in)
3) ![B=7.2in^{2},h=6.5in](https://tex.z-dn.net/?f=B%3D7.2in%5E%7B2%7D%2Ch%3D6.5in)
4) ![B=8.5in^{2},h=30in](https://tex.z-dn.net/?f=B%3D8.5in%5E%7B2%7D%2Ch%3D30in)
Step-by-step explanation:
1. You can calculate the volume of a cylinder with the following formula:
![V=B*h](https://tex.z-dn.net/?f=V%3DB%2Ah)
Where
is the area of the base and
is the height.
2. Therefore, you only need to multiply the area of the base by the height in each option:
1) ![V_1=15in^{2}*17in=255in^{3}](https://tex.z-dn.net/?f=V_1%3D15in%5E%7B2%7D%2A17in%3D255in%5E%7B3%7D)
2) ![V_2=7.2in^{2}*6.5in=46.8in^{3}](https://tex.z-dn.net/?f=V_2%3D7.2in%5E%7B2%7D%2A6.5in%3D46.8in%5E%7B3%7D)
3) ![V_3=34in^{2}*7.5in=255in^{3}](https://tex.z-dn.net/?f=V_3%3D34in%5E%7B2%7D%2A7.5in%3D255in%5E%7B3%7D)
4) ![V_4=8.5in^{2}*30in=255in^{3}](https://tex.z-dn.net/?f=V_4%3D8.5in%5E%7B2%7D%2A30in%3D255in%5E%7B3%7D)
3. Therefore, the options 1), 3) and 4) have equal volumes.
Answer:
The answer would be x*21/4 (this is all in a fraction)
