Answer:
x=10, y=4
Step-by-step explanation:
3x-3y=18
(-)3x-(-)8y=-(-)2 -3x+8y=2 add to first equation to eliminate x
5y=20
y=4
substitute y with 4
3x-3(4)=18
3x=30
x=10
x=10,y=4
It doesn't matter. It's the same distance from zero
The answer might be B, but realize if a circle is shifting both y and x can’t decrease.. and both cant increase at the same time.
Horizontal distance = 48'
difference in elevation = 18"-6" = 12" = 1'
Slope of the sewer line = rise/run = 1/48 = 0.0208 = 2.08%
Answer:
9
Step-by-step explanation:
Since 12 divided by 4 is 3, that is the constant. So 3 times 3 is 9
