X = tuna, y = BLT
x + y = 30
6x + 9y = 240
3y = 60
y = 20
x = 10
20 BLTs for $2.50, 10 tuna for $1.50
I got 0.03654595................... ignore me I'm dumb
Let w(s,t)=f(u(s,t),v(s,t)) where u(1,0)=−6,∂u∂s(1,0)=5,∂u∂1(1,0)=7 v(1,0)=−8,∂v∂s(1,0)=−8,∂v∂t(1,0)=6 ∂f∂u(−6,−8)=−1,∂f∂v(−6,−8

From the given set of conditions, it's likely that you are asked to find the values of

and

at the point

.
By the chain rule, the partial derivative with respect to

is

and so at the point

, we have


Similarly, the partial derivative with respect to

would be found via

ANSWER: 1 SOLUTION
Step 1: Subtract 2x-1 from both sides.
x2−(2x−1)=2x−1−(2x−1)
x2−2x+1=0
Step 2: Factor left side of equation.
(x−1)(x−1)=0
Step 3: Set factors equal to 0.
x−1=0 or x−1=0
x=1
Answer:
x=1
