Answer:
b
Step-by-step explanation:
is the situation could the expression model.
The standard form of this equation is

The slope of two parallel lines i the same, so the slope of the line we're looking for is also

Since the line passes through

, the equation is:

No because irrational cant be a simple fraction and 9/15
is 0.6
so... it is not irrational
Answer:
A 3 and 8
Step-by-step explanation:
if a/b=c/d, the extremes are "a" and "d". The means would then be "b" and "c"
C = 2m^2 + m
D = 2 - 6m + 2m^2
2C = 2(2m^2 + m) = 4m^2+2m
2D = 2(2-6m+2m^2) = 4-12m+4m^2
2C - 2D =
4m^2+2m-(4-12m+4m^2) =
4m^2+2m-4+12m-4m^2 =
0m^2 + 14m -4 =
14m - 4
