Given that m || n, what must be true of the two lines? Check all that apply. Line mand line n have different slopes.
Line m and line n have different y-intercepts.
The lines have the same steepness.
Eventually the lines will intersect.
Line m and line n lie on the same plane.

step-by-step explanation:

d

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06
