Guest, you're literally posting your homework, your whole worksheet on this forum. Seriously, can you please try and do it yourself, and then ask for help? You're truly not helping yourself learn.
x-axis and y-axis are two sides of the triangle.
So, you should substitute x=0 and y=0 in 2x+y=8
substituting x=0 gives you y=8, (height of triangle) substituting y=0 gives us x=4 (base of triangle)
1. x is original price
2. length is 4, rectangular floor area is 32/3
32/3 divided by 4=8/3
If the area is (x-3)/(x-2) and the length is 9x-3x^2, then the width is (x-3/(x-2) divided by 9x-3x^2.
Do these problems yourself first, and only post the questions you don't know. First try yourself. Seriously, don't post your homework on this site :)
First find the equation of the line:
slope of line is (-2-7)/(-3-(-1)=9/2
in point slope form: y-7=9/2(x+1)
The common ratio is r
18, _, _, -2/3
-2/3 divided by 1/3=-1/3
18, -6, _, -2/3
18, -6, 2, -2/3
so (4) -1/3
is the right answer
x is time it takes for 20 members to paint a 9000 square foot wall
