A is a function because you have a different value for x.
B is not a function because you can't have the x value have a number twice, in this case it's 2.
C is not a function for the same reason as B.
D is a function because there is always a different x value.

Hope I didn't mess up for your sake

BRAINLIEST!!!<br> 11. Solve the inequality and graph the solution on a number line.
PilotLPTM [1.2K]

Answer:

y≤-1/3 (fraction)

And on the number line it will start from -1/3 (-0.333) and go less than -1/3 ( to the left, and it will be shaded

Step-by-step explanation:

First we expand the brackets, making it -15y+12≥17

Then we move 12 to the other side, making it negative, -15y≥17-12

Simplify, -15y≥5

Then we divide on both sides to isolate y, flipping the greater than sign to less than because when you divide or multiply by a negative number, the sign flips. y≤5/-15

Then we simplify by dividing the fraction by 5, making it -1/3. y≤-1/3

If you have any doubts, inform me

The height of a cone is twice the radius of its base.
lara [203]

Answer:

A. \frac{2}{3} \pi x^3

Step-by-step explanation:

From the way the answers are presented, it can be seen that x refers to the radius of the base of the cone

radius: x

and we are told that the height is twice the radius, so:

height: 2x

and now we use the formula to calculate the volume of a cone:

V=\frac{\pi r^2h}{3}

where V is volume, r is radius, and h is the height. and \pi is a constant

in this case

r=x

h=2x

so we substitute thisvalues  in the formula for the volume:

V=\frac{\pi x^2(2x)}{3}

Rearranging the terms

V=\frac{2\pi x^3}{3} \\V=\frac{2}{3} \pi x^3

which is option A.
