solve each equation for y. do x and y vary directly? if so indentify the constant of variation.
the area of a parallelogram is 85 square meters and its base is 17 meters long.
what is the height of the parallelogram?

area of a parallelogram = base x height
85 = 17(height)
height = ...
i need help with math
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 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
