Which equation represents a direct variation? Whag is the constant variation

A. 3y=-2x+1;1
B. Y=-5x-11;5
C. 4y=-12x;3
D. Y+7=2x-1;7

Find the value of x. give reasons to justify your solutions! h ∈ ig

Rewrite so the subject can be y in the formula d=m-y/y+n

Scenario: a rectangular plot of ground is 5 meters longer than it is wide. its area is 20,000 square meters. question: what equation will you find the dimensions? note: let w represent the width. options: w(w+5)=20,000 w^2=20,000+5 (w(w+5))/2=20,000 w+2(w+5)=20,000
