Factor out the coefficient of the variable 5/6s+2/3
DochEvi [55]
Okay. so I'm gonna assume you know what factor out means--were gonna take out 5/6. what we need to know is, how does that affect our ending number 2/3? well, we're gonna have 5/6 times some stuff first off, right?

5/6 ( )

so what's in the parenthesis? well, if we distribute in our mind, S would just have to be by itself for it to work out. so we have

5/6 ( s )

but what about 2/3? well, if we're multiplying everything on the inside by 5/6, how can be get it to cancel and leave 2/3 alone? we could divide 2/3 by 5/6, right?

5/6 ( s + (2/3) / (5/6) )

now, when we distribute our 5/6, we'll have just 2/3 at the end. now let's simplify that end term so it looks a little better. if we divide by a fracion, that's the same as multiplying by the flipped version, so let's do that.

2/3 / 5/6 = 2/3 × 6/5 = 2 (6) / 5 (3) = 12/15

we can reduce 12/15 by dividing the top and bottom by three.

= 4/5

so our final answer would be:

5/6 [S + 4/5] you can redistribute to make sure it matches. Anyway, hope that helps!

-6, -6) and (-2, -2)<br> Find the rate of change of the line that passes through the points.
Kamila [148]

Rate of change of line that passes through the given points is 1

Step-by-step explanation:

The ratio of vertical and horiontal changes is called the rate of change of a line. It is called slope which is denoted by m.

The formula for slope when (x1,y1) and (x2,y2) are the points on line is given by:

m = \frac{y_2-y_1}{x_2-x_1}\\

Given

(x1,y1) = (-6,-6)

(x2,y2) = (-2,-2)

Putting the values in the formula

m = \frac{-2-(-6)}{-2-(-6)}\\=\frac{-2+6}{-2+6}\\=\frac{4}{4}\\= 1

Rate of change of line that passes through the given points is 1
