Answer:
D.) This system has infinitely many solutions
Step-by-step explanation:
y = -4x - 6
-4x - y - 6 = 0
-4x - y - 6 = 0
-y = 4x + 6
-y/-1 = 4x/-1 + 6/-1
y = -4x - 6
There are infinitely many solutions, because both of the lines are exactly the same. As show below ! Hope this helps once again ^w^
Answer:
<h2>
972 pi ft^3</h2>
solution,
Volume of this composite figure
= Volume of cylinder+volume of cone
Formula to find volume of cylinder:
![\pi \: {r}^{2} h](https://tex.z-dn.net/?f=%5Cpi%20%5C%3A%20%20%7Br%7D%5E%7B2%7D%20h)
Formula to find volume of cone:
![\frac{1}{3} \pi {r}^{2} h](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20h)
Use,
![\pi = \: pi](https://tex.z-dn.net/?f=%5Cpi%20%3D%20%20%5C%3A%20pi)
Here,
Radius of cone= radius of cylinder
=9 ft
Height of cylinder=10 ft
Height of cone=16 ft-10 ft=6 ft
Nowz
Volume of the figure:
![\: pi \: {r}^{2} h + \frac{1}{3} \: pi \: {r}^{2} h \\ = \: pi \times {(9)}^{2} \times 10 + \frac{1}{3} \times \: pi \times {(9)}^{2} \times 6 \\ = \: pi \: \times 81 \times 10 + \frac{1}{3} \times 21 \times 6 \times \: pi \\ = 810 \: pi + 162 \: pi \\ = 972 \: pi \: {ft}^{2}](https://tex.z-dn.net/?f=%20%5C%3A%20pi%20%5C%3A%20%20%7Br%7D%5E%7B2%7D%20h%20%2B%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%5C%3A%20pi%20%5C%3A%20%20%7Br%7D%5E%7B2%7D%20h%20%5C%5C%20%20%3D%20%20%5C%3A%20pi%20%5Ctimes%20%20%7B%289%29%7D%5E%7B2%7D%20%20%5Ctimes%2010%20%2B%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Ctimes%20%20%5C%3A%20pi%20%5Ctimes%20%20%7B%289%29%7D%5E%7B2%7D%20%20%5Ctimes%206%20%5C%5C%20%20%3D%20%20%5C%3A%20pi%20%5C%3A%20%20%5Ctimes%2081%20%5Ctimes%2010%20%2B%20%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Ctimes%2021%20%5Ctimes%206%20%5Ctimes%20%20%5C%3A%20pi%20%5C%5C%20%20%3D%20810%20%5C%3A%20pi%20%2B%20162%20%5C%3A%20pi%20%5C%5C%20%20%3D%20972%20%5C%3A%20pi%20%5C%3A%20%20%7Bft%7D%5E%7B2%7D%20)

102, first you subtract 1 from 4 so thats 3 and then you add the 32 and 2 so now all you have to do is multiply the results of 4-1 and 32+2
Answer:
24
Step-by-step explanation:
you can turn 3/4 in to a decimal the after you get the decimal you would divide by 18. 0.75 divide by 18 = 24
