What is the answer??
Dovator [93]

Answer:

y₂ = 3

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - \frac{3}{4}

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (7, - 6) and (x₂, y₂ ) = (- 5, y₂ )

m = \frac{y_{2}+6 }{-5-7} , that is

\frac{y_{2}+6 }{-12} = - \frac{3}{4} ( cross- multiply )

4(y₂ + 6) = 36 ( divide both sides by 4 )

y₂ + 6 = 9 ( subtract 6 from both sides )

y₂ = 3

Find the 2 critical points of the given function and then determine whether it is a local maximum, local minimum, or saddle poin
grandymaker [24]

Answer:

Step-by-step explanation:

Given is a function f in two variables as

f(x, y) = (x − y)(xy − 9)

To find critical points of the given function and also to find max, min or saddle point.

Find the partial derivatives

f(x,y) = x^2y-xy^2-9x+9y

f_x=2xy-y^2-9\\f_y =x^2-2xy+9\\f_{xy}  =2x-2y = f_{yx}

f_{xx}=2y\\ f_{yy}=-2x

Equate first derivatives to 0

Adding fx and fy we get

x^2-y^2 =0\\

x=±y

Only real roots are (x,y) =(3,3) and (-3,-3)

D(3,3)=f_{xx}(3,3) f_{yy}(3,3)-f_{xy}^2(3,3) \\=-36-0

(3,3) is a saddle point

D(-3,-3) = -36

(-3,-3) is also a saddle point.

Find the slope of the line passing through the given points or the given line.
ad-work [718]

Answer:

y = -1

Step-by-step explanation:

since this is a straight, horizontal line, we know that this will just be a y value line

since the line passes through the y axis at y = -1, this is the equation for the line

y = -1
