Answer:
Both lines are not parallel
Step-by-step explanation:
Given as :
Two lines equation are as :
3y - 5x = 9 And y = - 
x - 12
First line is now written in eq y = mx + c
Or, 3y = 5x + 9
Or, y = x + 
So, Slop of this line ( m 1 ) =
slop of second line ( m 2) is 
∵ The slop of both lines are not equal , so the line are not parallel to each other .
Hence Both lines are not parallel Answer
Lines cannot intersect at multiple points...so the answer would have to be C :)
Answer:
6.4 m
Step-by-step explanation:
We have 2 expressions here. The first one is the fact that r = y. That's one of 2 equations. The second one involves whats' left after cutting off certain lengths of each color string. We cut 2.5 m from red, we cut 3.8 m from yellow. We know that what's left of red is 1.5 times the length of what's left of yellow. What's left of red is r - 2.5; what's left of yellow is y - 3.8. We know that r = 1.5y, so filling that in with our corresponding expressions gives us
r - 2.5 = 1.5(y - 3.8)
Distribute to get
r - 25 = 1.5y - 3.2
Now from the first expression, r = y, so fill in y for r to get an equation in one variable:
y - 2.5 = 1.5y - 3.2
Combine like terms:
-.5y = -3.2 and divide to get
y = 6.4
Check it to make sure it works. What's left of red should be 1.5 times the length of what's left of yellow and y = 6.4:
What's left of red: 6.4 - 2.5 = 3.9
What's left of yellow: 6.4 - 3.8 = 2.6
1.5 x 2.6 = 3.9, just like it should!
