Step-by-step explanation:
4x+13y=-9y+3y=33
17x=-6y=33
Answer:
y = -2
Step-by-step explanation:
First, we subtract 2y on both sides:
-24 = 12y
Then, we divide 12 on both sides:
y = -2
And we're done ^^ hope this helps!
Y = -1
x = 5

You can multiply 2/3 by 2/2 to get 4/6. This means that x=4!!!
Hope this helps :)
I'm guessing the second derivative is for <em>y</em> with respect to <em>x</em>, i.e.

Compute the first derivative. By the chain rule,

We have


and so

Now compute the second derivative. Notice that
is a function of
; so denote it by
. Then

By the chain rule,

We have

and so the second derivative is
