X+1=y and 3y-7=2x are your two equations.
Substitute x+1 in for y
3(x+1)-7=2x
3x+3-7=2x
x-4=0
x=4
Plug in 4 for x in either equation to solve for y
x+1=y
4+1=y
5=y
x=4 and y=5
Hope I could help!
L: Large
s: Small
-2 (2L + 3s = 46)
4L + 8s = 105
-4L - 6s = -92
4L + 8s = 105
2s = 13
s = 6.5 kilograms
2L + 3 ( 6.5 ) = 46
2L + 19.5 = 46
2L = 26.5
L = 13.25 kilograms.
Answer:
Distance = 8.6
M = (-13.5,27.5)
Step-by-step explanation:
Distance =
=
=
=
=
=
= 8.6
Midpoint =
= (-10+(-17)) ÷ 2 ; (30+25) ÷ 2
= -27 ÷2 ; 55 ÷ 2
= -13.5, 27.5
Answer:
true
Step-by-step explanation:
you must assume its false and if said statement leads to an impossibility then its proved to be true
