Answer:

-4

Step-by-step explanation:

(x1,y1)=(-10, -8)

(x2,y2)=(-8, -16)

Slope=(y2-y1)/(x2-x1)=(-16+8)/(-8+10)=-8/2=-4

or,

If you take (x1,y1)=(-8, -16), (x2,y2)=(-10, -8)

Slope=(y2-y1)/(x2-x1)=(-8+16)/(-10+8)=8/-2=-4

Please answer :D Rearrange the linear equation so that it is in slope-intercept form. Identify the slope (m) and the y-intercept

yKpoI14uk [10]

Answer:

$y=\frac{1}{2}x+1$

The slope is 1/2.

The y-intercept is 1.

Step-by-step explanation:

We have:

$x-2=2(y-3)$

Let’s divide both sides by 2. This gives us:

$\frac{x}{2}-\frac{4}{2}=y-3$

Simplify:

$\frac{1}{2}x-2=y-3$

Add 3 to both sides:

$\frac{1}{2}x+1=y$

Flip:

$y=\frac{1}{2}x+1$

This is in the slope-intercept form:

$y=mx+b\\$

Where m is the slope and b is the y-intercept.

Hence, our slope m is 1/2 and our y-intercept b is 1.

Determine the total number of roots of each polynomial function using the factored form. f (x) = (x + 5)3(x - 9)(x + 1)

densk [106]

Answer:

Answer is 5

Step-by-step explanation:

Okay hun so let me tell u what's up here

They give us this equation and ask for the 'roots'

(x+5)^3(x-9)(x+1)

Now lemme tell you the roots of this one

-5, 9, -1

you get this from making each of them 0

The answer to this would be "3" because there are 3 roots, buT wait theRe'S mOre

(x+5) goes 3 times

So thy must recount it

-5, -5, -5, 9, -1 <-- These are the roots

that's 5 roots in total

....also I did this on edgen, got it right with 5

Pick any value in the y column of the table. I'm going to pick 81. Divide the value you picked by the previous y value, which in my case would be 9

Dividing the values gives: 81/9 = 9

So the base is 9. We multiply each y value by 9 to get the next y value
Eg: to go from 1/81 to 1/9, we multiply by 9. Same for 1/9 to 1, and so on.

Answer: Choice B) 9

Note: This trick only works because x is increasing by 1 each time
