Someone please help me

Mars2501 [29]

Answer:

x=-1,-2

Step-by-step explanation:

Multiply the given equation with (x+1) on both sides. We'll get,

x+2/x=-3

or,x^2+2=-3x

or,x^2+3x+2=0

or,x^2+2x+x+2=0

or,x(x+2)+1(x+2)=0

or,(x+2)(x+1)=0

or,x=-2,-1

Four points from a line are shown in the table below.

Dvinal [7]

Answer:

Correct choice is D. $y=-x+3$ .

Step-by-step explanation:

pick any two points from the table say (0,3) and (1,2)

Now we we can use both points to find the equation of line.

slope $m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-3}{1-0}=\frac{-1}{1}=-1$

now plug slope m=-1 and any point say (0,3) into point slope formula

$y-y_1=m\left(x-x_1\right)$

$y-3=-1\left(x-0\right)$

$y-3=-1\left(x\right)$

$y-3=-x$

$y=-x+3$

Hence correct choice is D. $y=-x+3$ .
