Which statement is true about the graphs of the two lines y= -8x - 5/4 and y= 1/8 x + 4/5?

Step-by-step explanation:

If we have two lines of equations:

        (1)

       (2)

Where n is the slope of the line (1) and m is the slope of the line (2)

Then by definition it is fulfilled that if means that the lines (1) and (2) are perpendicular

In this case the lines are:

    (1)

       (2)

Observe that:      and    

Then it is fulfilled that  because:

Therefore the lines are perpendicular

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.

you!
