X - y = 7
y = x - 7....the slope here is 1. A parallel line will have the same slope.
y = mx + b
slope(m) = 1
(1,0)...x = 1 and y = 0
now we sub and solve for b, the y int
0 = 1(1) + b
0 = 1 + b
-1 = b
so ur parallel line is : y = x - 1
Answer:
he has 12/18th's of the marbles.
work:
18/18 - 6/18 = 12/18
1)1.10w+2.35(172-s)=294.20
When you solve
1.10x+2.35(172-x)=294.20 solve for x
X water=88
S=172-88=84
2)2t+4(40-f)=100
When you solve
2x+4(40-x)=100 solve for x
X=30 for t
40-30=10 for f
Hope it helps
