The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate.

Which equation represents a line that passes through the two points in the table x 1,5 and y 1,6

aleksandrvk [35]

For this case we must find a linear equation of the form:

$y = mx + b$

Where,

m: slope of the line

b: cutting point with vertical axis.

For the slope we have the following equation:

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

Substituting values we have:

$m = \frac {6-5} {1-1}\\m = \frac {1} {0}$

We observe that the slope of the line is not defined.

Therefore, the line is vertical.

Thus, the equation of the line is given by:

$x = 1$

Answer:

The equation of the line is given by:

$x = 1$

Giải các phương trình vi phân sau y' - y/x+1 = 2

KatRina [158]

It looks like the differential equation is

$y'-\dfrac y{x+1}=2$

Multiply both sides by 1/(x + 1) :

$\dfrac{y'}{x+1}-\dfrac y{(x+1)^2} = \dfrac2{x+1}$

The left side is now a derivative of a product,

$\left(\dfrac y{x+1}\right)' = \dfrac2{x+1}$

Integrate both sides with respect to x :

$\dfrac y{x+1} = 2\ln|x+1|+C$

Solve for y :

$y = 2(x+1)\ln|x+1| + C(x+1)$

Answer:

-5/2 x -33/4

Step-by-step explanation:

(-11/2 x + 3) -2 (-11/4 x -5/2)

(-11/2 x + 3/1) -2 (-11/4 x -5/2)

The LCM of 2 and 1 is 2, and the LCM of 4 and 2 is 4.

(-11/2 x + 6/2) -2 (-11/4 x -20/4)

( -5/2x) -2 (-31/4)

-5/2x -2 -31/4

-5/2x -2/1 -31/4

LCM of -2 -31/4 is 4

-2/4 -31/4

-33/4

-5/2x -33/4 in simplest form.
