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

the area of a parallelogram is 85 square meters and its base is 17 meters long.

what is the height of the parallelogram?

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

Do not post a new question as a reply to another persons problem.

area of a parallelogram = base x height
85 = 17(height)
height = ...

i need help with math

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 2x-3

and y is greater than or equal to -3x. how do you solve for those equations ?

express the following as positive exponets

what is the solution set for x^2-25 is less than or equal to 0
