Answer:

The answer is 3 , 1 , 2 .

Step-by-step explanation:

I will give an example.

e.g.

x² + 3x + 2

Step 3 :

Set the equation equal to zero :

x² + 3x + 2 = 0

Step 1 :

Completely factor the equation :

x² + x + 2x + 2 = 0

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

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

Step 2 :

Set each factor equal zero and then solve for the variable :

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

x + 2 = 0

x = -2

x + 1 = 0

x = -1

<u>Hello:</u>

<u />

<u>Okay, this problem should be taken in a series of steps</u>:

<u>What is the slope's formula?</u>

$\rm\hookrightarrow \frac{y_2-y_1}{x_2-x_1}$

(x₁,y₁) -- first point
(x₂,y₂) -- second point

<u>Okay, now let's use this knowledge</u>

10. (5,-19) and (-5,21)

$Slope = \frac{21--19}{-5-5} =\frac{40}{-10}=-4$

11. (12,1) and (12, -1)

$Slope = \frac{-1-1}{12-12} =\frac{-2}{0}$

12. (8,7) and (4,7)

$Slope = \frac{7-7}{4-7} =0$

<u>Answer:</u>

Question 10: -4
Question 11: undefined
Question 12: 0

Hopefully that helps!

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Check al

natka813 [3]

Find the slope of the line first:
5x - 2y = -6,
y = (5/2)x + 3;
Since we need a line that's perpendicular, m = - (2/5).

The only equation that has the slope of this m is 2x + 5y = -10;
