What is the equation standard form of through (2,-4))and the slope is -4

Sloan [31]

Answer:

4x + y = 4

Step-by-step explanation:

Equation of Line in point slope form is given as:

$y - y_1= m(x-x_1)$

Plug $x_1= 2\: and\: y_1= - 4$ in the above equation we find:

$y - ( - 4) = - 4(x - 2) \\ \\ y + 4 = - 4x + 8 \\ \\ 4x + y + 4 - 8 = 0 \\ \\ 4x + y - 4 = 0 \\ \\ 4x + y = 4 \\this \: is \: the \: required \: equation.$

Find the solution to the system of equations. You can use the interactive graph below to find the solution. { y = x − 4 y = 4 x

kumpel [21]

ANSWER

$x=-2,y=-6$

EXPLANATION

First equation:

$y = x - 4$

Second equation:

$y = 4x + 2$

Let us equate the two equations and solve for x.

This implies that;

$4x + 2 = x - 4$

Group similar terms to obtain:

$4x - x = - 4 - 2$

Simplify:

$3x = - 6$

Divide both sides by 3

$x = - 2$

Put x=-2 into any of the equations.

I will put x=-2 into the first equation:

$y = - 2 - 4$

This implies that,

$y = - 6$

Consider F and C below. F(x, y, z) = yz i + xz j + (xy + 6z) k C is the line segment from (2, 0, −2) to (5, 4, 2) (a) Find a fun

WITCHER [35]

Answer:

Required solution (a) $f(x,y,z)=xyz+3z^2+C$ (b) 40.

Step-by-step explanation:

Given,

$F(x,y,z)=yz \uvec i +xz\uvec j+(xy+6z)\uvex k$

(a) Let,

$F(x,y,z)=yz \uvec i +xz\uvec j+(xy+6z)\uvex k=f_x \uvec{i} +f_y \uvex{j}+f_z\uvec{k}$

Then,

$f_x=yz,f_y=xz,f_z=xy+6z$

Integrating $f_x$ we get,

$f(x,y,z)=xyz+g(y,z)$

Differentiate this with respect to y we get,

$f_y=xz+g'(y,z)$

compairinfg with $f_y=xz$ of the given function we get,

$g'(y,z)=0\implies g(y,z)=0+h(z)\implies g(y,z)=h(z)$

Then,

$f(x,y,z)=xyz+h(z)$

Again differentiate with respect to z we get,

$f_z=xy+h'(z)=xy+6z$

on compairing we get,

$h'(z)=6z\implies h(z)=3z^2+C$ (By integrating h'(z)) where C is integration constant. Hence,

$f(x,y,z)=xyz+3z^2+C$

(b) Next, to find the itegration,

$\int_C \vec{F}.dr=\int_C \nabla f. d\vec{r}=f(5,4,2)-f(2,0,-2)=(52+C)-(12+C)=40$

ella [17]

Answer:

9ft. 2in.

Step-by-step explanation:

17ft. 5in. = 209in.

8ft. 3in. = 99in.

209in. - 99in. = 110in.

110 in. = 9 ft. 2 in.
