How to solve 3y+6=5y-18

Mathematics

(1. Subtract 5y form both sides)
(-2y + 6 = -18)
(2. Subtract 6 from both sides)
(-2y = -24)
(Divide both sides by -2)
(y = 12)

Answer:

y = 14

Step-by-step explanation:

move 5y over to the left and you should get -2y +6=-18. subtract 6from both sides and you will now have -2y=-24. divide bothe sides from -2 and you will get y=14

Find the local extreme values of the function f(x, y) = xy - x2 - y2 - 3x - 3y + 12
aev [14]
f(x,y)=xy-x^2-y^2-3x-3y+12

First compute the first-order partial derivatives and find the critical points.


f_x=y-2x-3
f_y=x-2y-3

Both first order derivatives vanish at (x,y)=(-3,-3).


Computing the Hessian, we get

\mathbf H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}-2&1\\1&-2\end{bmatrix}

We have \det\mathbf H(x,y)=3>0, which means (-3,-3) is an extremum of f(x,y). Since f_{xx}(-3,-3)=-2, this extremum is a local maximum of f(x,y) with a value of 21.

What is the value of x?
Kryger [21]
-1 because -3x+1=2 (4 total spaces) so,
2+1 is 3 
you have life numbers and x values separate. 
divide positive 3 by negative 3 to get -1. 
check your answer by plugging it in
-1*-3 is 3 
so - 3+1 world be 4 which is where the 2 is on the number line because it goes into negatives 

answer is x= -1

Answer:

  F(x) = (9/5)x -459.67

Step-by-step explanation:

F(C(x)) = 9/5(x -273.15) +32

F(C(x)) = (9/5)x -459.67 . . . . . simplify
