Find the dimensions of an american football field. the length is 200 feet more than the width, and the perimeter is 1040 feet. find the length and width?

Step-by-step explanation:

Perimeter = 2* Length + 2* Width

1040 = 2*(X+200) +2*X

1040 = 4x +400

640 = 4x

160 = x

Width = 160

Length = 360

test: 2x 160 = 320 /// 2x 360 = 720

720+320 = 1040

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
