-3y = x...so we sub in -3y for x in the other equation
-x + 7y = 70
-(-3y) + 7y = 70
3y + 7y = 70
10y = 70
y = 70/10
y = 7
so we sub in 7 for y in either of the original equations to find x
-3y = x
-3(7) = x
-21 = x
so ur solution is (-21,7)
Answer:
Step-by-step explanation:
Start on the x-axis, the horizontal one Start at (0,0), where the two lines meet. Then go over to the right 2 tic marks. Then go up the y-axis, the vertical one, 5 tic marks.
Answer:
If it's where they can get to the building I think it's 15
Step-by-step explanation:
Cause 10 plus 5 and if that can reach where they are able to get in I'd assume it would be 15
I'm not a genius or anything so don't rely on my answer
Answer:
a
Step-by-step explanation:
uh
C- charge
H- hours
D- diagnostic fee
C= #H(90)+ D
C= 4.6(90)+50
=414+50
=$464
C-$800
H-?
D-50
C= #H(90)+50
800=H(90)+50
H(90)=800-50
H(90)=750
H(90)/90=750/90
H=750/90
H= 8.33333333
