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.
y+6+x=12, y+x=6
12+x=3y, 3y-x=12
4y=18
y=9/2

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)
Area=(1/2)(8)(4)=16
1. x is original price
0.7x=96*0.7=67.20
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.
\(\frac{\frac{x-3}{x-2}}{9x-3x^2}=\frac{x-3}{\left(x-2\right)\left(9x-3x^2\right)}=\frac{x-3}{\left(x-2\right)\cdot \:3x\left(3-x\right)}=-\frac{1}{3x\left(x-2\right)}\)
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)
y-7=9/2x+9/2
y=9/2x+23/2
substitute x
y=9/2(-6)+23/2
y=-31/2
The common ratio is r
a1=18, a4=-2/3
18, _, _, -2/3
-6/18=-1/3
-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
x/9000=24/6000
x=24/6*9
x=36 minutes
Arc LPM=360-72=288°
