Answer:
x = - 1
y = - 3
z = -2
Step-by-step explanation:
Please see steps in the image attached here.
Lines are perpendicular if the slope of one is the negative reciprocal of the other. In this case the slopes are -8/3 and 8/3, so while negative they are not reciprocal. So no, the two lines intersect but are not perpendicular.
Answer:
Step-by-step explanation:
use Area=pi * 
diameter is 2 * r
so r = 5
pi *
= 78.5398
Area * height = volume
78.5398 * 17 = 1335.18
the cylinder holds about 1335 
60*80%=
60*0.8 = 48
one of your choices should be 48 or something close to 48
