Well I don't know !
Let's get together and figure it out. Are you with me ?
You said that 8x - 2 = -9 + 7x
Add 2 to each side: 8x = -7 + 7x
Subtract 7x from each side: x = -7
Now that wasn't so bad, was it ?
Im going to assume that 3√ is √3
And √3 is irrational because You cant square root it without getting nuked with a Random Number generator of decimals.
<u>3x + 2y = 4</u>
Here are a few different ways
to represent the same line:
2y = 4 - 3x
y = -1.5x + 2
5y = -7.5x + 10
3x = 4 - 2y
x = -2/3y + 4/3
-5 + 17 = 12 you will do inverse operations.
400/(1+e^-x)=350
400=350(1+e^-x)
400=350+350e^-x
350e^-x=400-350
350e^-x=50
e^-x=50/350
e^-x=1/7
ln e^-x=ln (1/7)
-x ^(ln e)=ln1-ln7
-x(1)=0-ln7
x=ln7
Answer: x= ln 7 ≈1.94591...
