Your help would be very greatly appreciated.
FLVS question:

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

umumumumum

im not sure

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

the answer is a if my teacher taught me correct
