3y=4x+15 and 9x+12y=12 are perpendicular, parallel or neither

These two linear equations are perpendicular, because 3y=4x+15 has a slope of and 9x+12y=12 has a slope of - , and since those two fractions have exact opposite slopes (flip the denominator and numerator and multiply by -1), they are perpendicular.

i don't even know man. edge inuity be messing with us. i had to ask a question too.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
