Answer:
Step-by-step explanation:
Give the DE
dy/dx = 1-y
Using variable separable method
dy = (1-y)dx
dx = dy/(1-y)
Integrate both sides
∫dx = ∫dy/(1-y)
∫dy/(1-y)= ∫dx
-ln(1-y) = x+C
ln(1-y)^-1 = x+C
Apply e to both sides
e^ln(1-y)^-1 = e^,(x+C)
(1-y)^-1 = Ce^x
1/(1-y) = Ce^x
Answer:

<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define expression</u>
4(-8x + 5) - (-33x - 26)
<u>Step 2: Simplify</u>
- Distribute: -32x + 20 + 33x + 26
- Combine like terms (x): x + 20 + 26
- Combine like terms (Z): x + 46
Answer:
48
Step-by-step explanation:
16/20. We reduce that and get 4/5.
After this it's much simpler to chage it.
100 dividied by 5 is 20. (20,40,60,80,100)
So the 4th number (4/100)
is 80. 80%.
20% she didn't and 80% she did :) (100-80)
Answer:
6x
Step-by-step explanation:
Step 1: Write equation
x + 2x + 3x
Step 2: Combine like terms
3x + 3x
6x
