A rectangular field is 4 times as long as it is wide. If the length is decreased by 10 feet and the width is increased by 2
feet, the perimeter will be 80 feet. Find the dimensions of the original fleld.
The original dimensions are
"feet long by
'feet wide.

80 feet

Step-by-step explanation:

L=4w following by the increase or 2

2(L-10) + 2(W+2) = 80

38.4   &  9.6

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
