solve each equation for y. do x and y vary directly? if so indentify the constant of variation.
1.4x=5y
2.2x+3y=6

Do not post a new question as a reply to another persons problem.
use "Post a New Question" above.
area of a parallelogram = base x height
85 = 17(height)
height = ...

4x  5y = 0 (#1)
4x + 6y = 12 (#2 x 2)
11y = 12 I subtracted them
y = 12/11
back in #1
4x = 5(12)/11
x = 15/11

it is about inequalities. i have to solve them graphically and shade the solution set.then i have to identify teo points within the solution set and two points not within the solution set. they are y is less than 2x3
and y is greater than or equal to 3x. how do you solve for those equations ?
