Answer: GCF of 40 and 42 is 2
Answer:
D. y = x - 3
Step-by-step explanation:
Parallel lines are when 2 lines have the same slope but different y-intercepts.
For example:
x+2y=7
6x+7y=2
__________
x=7-2y *
6*(7-2y)+7y=2 **
__________
x=7-2y
42-12y+7y=2
__________
x=7-2y
-5y=-40
__________
x=7-2y
y=8
x=-9
Remember you can do anything to an equaiton as long as you do it to both sides
-x=4-3x
add 3x both sides
3x-x=4+3x-3x
2x=4+0
2x=4
divide 2
2x/2=4/2
2/2x=2
1x=2
x=2
