This is an ODE of the form y' + P(x)y = Q(x)
IF =
Multiply through by IF
But y(0) = 1
Therefore, solution is
The weight of 10 fish would be 23.5 pounds. If 100 fish is 235 pounds, then each fish is 2.35 pounds. 10 fish of that same weight would be 23.5 pounds.
Answer:y= 2x+7
Step-by-step explanation:
They are all pretty much want you to create the equation so the formula they want is y=mx+b format.
First problem(1,9) slope 2
Y=mx +b
Where y is 9,x is 1 and slope (m) is 2.
Now solve for b using equation
Y=mx +b
9= 2(1)+b
9=2+b
9-2=b
7=b
Now you can create equation
Y= 2x+7
Prob.4
(3,-6) and (-1,2)
First find slope
M= y2-y1/x2-x1
M= 2-(-6)/-1-3
M = 8/-4
M= -2
Your slope "m" is -2
Now do as problem 1 get one of the points and your slope to get equation .
(3,-6) slope -2
Y=mx+b
-6= -2(3)+b
-6= -6+b
-6+6=b
0=b
Y= -2x
Problem 7
(5,13) (10,14)
You solve this one as problem 4 same steps that I did above .
Problem 8 is also the same as steps in problem 4
( 2,160) and ( 2.75,220)
I hope this helps you

Answer:
HEY YOU! Yes, you, sitting behind your screen reading this. I don't know you and you certainly don't know me. But I want to tell you something. Everyone has their own story. Yours might be filled with joy and happiness, or it might be clouded with pain and misfortune. I want you to know that you're a beautiful, wonderful, talented person. Even if your life isn't going the way you want it to right now, I know that you'll be able to make it out alright. I want you to do me a favor. I know I'm just a stranger, but just trust me, okay? Every time you see your reflection, be it in the mirror in the bathroom, in a window somewhere, or in a puddle on the street, I want you to look at yourself and give yourself a hug. Because even if you aren't the prettiest or the smartest or the funniest, you're something that no one else can be: you. And you are the greatest thing you can be. Smile at strangers. Be confident in yourself. Cry when you feel like crying, laugh when you feel like laughing. Treat yourself like a god/goddess because you deserve it. Hold your head up and keep your heart open. You're worth everything and then some. And always remember that no matter what, even if it doesn't seem like it, you're everything to someone. I was bullied for so long and was told that I wasn't beautiful, and it broke me down. But I realized that I am beautiful and so is everyone else. I wanted to make sure no one felt upset like I did
