Answer:

Step-by-step explanation:

7w+w-15=17

8w=17+15 add like terms

8w=32 divide

w=32/8=4

now check

7*4+4-15=17

28+4-15=17

17=17

Helppppppp pleaseeeeee

All you have to do is plug in the number for x, and find y. I will write this out as if in that chart you have shown.

x y = 9 - 3x y

_______________________________________

0 y = 9 - 3(0) 9

1 y = 9 - 3(1) 6

2 y = 9 - 3(2) 3

3 y = 9 - 3(3) 0

Hope that helps!!

The diameter of the base of the cone measures 8 units.

weeeeeb [17]

Answer: $32\pi$ cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

$V_{cone}=\frac{1}{3}\pi r^2h$

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

$r=\frac{8units}{2}\\\\r=4units$

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:

$V_{cone}=\frac{1}{3}\pi (4units)^2(6units)$

$V_{cone}=32\pi \ units^3$
