Hi there!

To find the slope of a line when we have 2 points, we use this formula:

m=\frac{y2-y1}{x2-x1}

where m is the slope.

\frac{7-7}{7-3}

Notice that if we subtract the y-coordinates, we get 0. We know that 0 divided by any number is 0.

So the slope of this line is 0.

So if the y-coordinates are the same, then the slope is 0.

Now, let's find the slope of the next line.

\frac{-5-3}{-4-(-4)} \\\frac{-8}{-4+4} \\\frac{8}{0}

Do you see what I see?

We cannot divide by 0 because division by 0 is undefined. So the slope of this line is undefined.

Remember:

  • If the y-coordinates are the same, then the slope is 0.
  • If the x-coordinates are the same, then the slope is undefined.

Hope this helps you!

PLEASE HELP ASAP 40 PTS
DochEvi [55]

Answer:

40 + 3x + 4 + 3x + 4 = 180

48+6x=180

48 - 48 + 6x = 180 -4 8

6x = 132

6x/6 = 132/6

x = 22

Step-by-step explanation:

1. since the triangle is isosceles, angles A and C will have the same measures, so to solve for x, you can add another 3x + 4 or you can multiply A by 2.

2. add like terms

3. subtract

4. divide to get x

Si el área de una figura rectangular esta dada por A-bxh,¿cual es la siguiente expresiones representa el área de la puerta
stealth61 [152]

Respuesta:

3x² + 5x - 2

Explicación paso a paso:

Dado que :

Área del rectángulo, A = largo * ancho

Dimensión = 3x - 1; x + 2

Área = (3x - 1) * (x + 2)

Área = 3x² + 6x - x - 2

Área = 3x² + 5x - 2

Help!! Gotta finish 2 units in 4 days!!
Step2247 [10]

Answer:

\large \boxed{\sf \ \ g(x)=3|x| \ \ }

Step-by-step explanation:

Hello,

Let's follow the instructions !

Step 1

g(x)=k*f(x)=k*|x|

We know that the point (2,6) is on the graph so 6=g(2) meaning:

6=k*|2|=k*2

*** divide by 2 both sides ***

k = 6/2 = 3

Step 2

g(x)=3*|x|

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Write the given roots to quadraatic equation
german

Answer:

It's like solving a quadratic, but in reverse, and in this case you'll arrive at x2+x−12=0

Explanation:

We're going to go "backwards" with this problem - normally we're asked to take a quadratic equation and find the roots. So we'll do what we normally do, but in reverse:

Let's start with the roots:

x=3, x=−4

So let's move the constants over with the x terms to have equations equal to 0:

x−3=0, x+4=0

Now we can set up the equation, as:

(x−3)(x+4)=0

We can now distribute out the 2 quantities:

x2+x−12=0
