Sloope intercept form is
y=mx+b
m=slope
b=y intercept =where the line passes through the y axis
we are given
line M has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2
line N has slope of 1 and passes through y axis at -2 (y intercept=-2)
equaton is therefor y=1x-2 or y=x-2
compare
line M: y=x-2
line N: y=x-2
they are the same line and lines extend infinitely so therefor there are infinite number of solutions
Answer:
wowww!! it's very sad and wonderfull
Answer: Is that the full question?
Step-by-step explanation:
I need more info
Substituting this into the other ODE gives
Since 
, it follows that 
. The ODE in 
has characteristic equation
with roots 
, admitting the characteristic solution
From the initial conditions we get
So we have
Take the derivative and multiply it by -1/4 to get the solution for 
:
$15,000 * 0.8 = $12,000
$12,000 * 0.8 = $9,600
$9,600 * .08 = $7,680
