Answer:

point slope form y-5 = -1(x-2)

slope intercept form y = -x +7

Step-by-step explanation:

We have the slope and a point, we can use the point slope form

y-y1 = m(x-x1)

y-5 = -1(x-2)

Distribute

y-5 = -x+2

This is the point slope form

We can also manipulate the equation into slope intercept form

Add 5 to each side

y-5+5 = -x+2+5

y = -x +7

Answer:

x = 8 or x = 2

Step-by-step explanation:

We know x - 5 = 3 or x - 5 = -3.

Possibility 1:

Step 1: Add 5 to both sides.

$x-5+5=3+5$
$x=8$

Possibility 2:

Step 1: Add 5 to both sides.

$x-5+5=-3+5$
$x=2$

Step 2: Check if both solutions apply to original equation.

$|8-5|=3$
$|3|=3$
$3=3$
$|2-5|=3$
$|-3|=3$
$3=3$

Answer:

$\frac{2x + 4}{2} < 6 \\ 2x + 4 < 2 \times 6 \\ 2x + 4 < 12 \\ 2x < 12 - 4 \\ 2x < 8 \\ x < \frac{8}{2} \\ \color{blue} \boxed{x < 4}$

How do you factor 24+18v. Please explain and show your work.

tamaranim1 [39]

So we take 6 out of each term so it is $6(4+3v)$ hope this helped.
