-1/7,0,1/7 is the answer!!!
-----------------
0.04m² - n²
(0.2m)² - n²
<span>(0.2m + n)(0.2m - n)</span>
-----------------
2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50
The slope is negative, so the slope is negative. Using the rise over run formula, the slope of the line should be -1.
