Answer:
None
Step-by-step explanation:
Step 1: Write all the equations in the form y=mx+c, where m represents the gradient.
Notably, the equations are in that form already.
Step 2: Compare which equation have same value of m
In our case, none, hence no parallel lines
Answer:
1:-3, 1:2
Step-by-step explanation:
She has to 40 more laps. 50% is a half, so 40 is half of something. so you are dividing 40 by a half, which is 80. half of 80 is 40.
75
Reduction of 12
3 x 4 = 12
Increase of 10
5 x 2 = 10
75 - 12 = 63
63 + 10 = 73
Change = 2 inches (75 - 73)
