Answer:
the slope is -8/5
Step-by-step explanation:
we need to get the equation in the form
y= mx+b where m is the slope and b is the y intercept
8x + 5y =40
subtract 8x from each side
8x-8x + 5y = -8x +40
5y = -8x+40
divide each side by 5
5y/5 = -8x /5 + 40/5
y = -8/5 x +8
the slope is -8/5 and the y intercept is 8
You find volume by multiplying width by length by height so
3 x 1 x 1 = 3
so the volume is 3 cubic meters and every cubic meter of hay costs $14 so
3 x 14 = 42
$42
Answer:

Step-by-step explanation:

All we can do here is combine like terms (add those that have the same the same exponent)

Good luck!
Answer:
Step-by-step explanation:
Y-Y1= m(x-x1)
Y-6=57(x-2)
Y-6=57x-114
Y=57x-108
0=57x-y-108
