D. 12.5

The equation to find the average rate of change is

$\frac{y2 - y1 }{x2 - x1}$

To find the average rate of change between points (0,20) and (8,120) you need to plug it into the equation so it'll be

$\frac{120 - 20}{8 - 0}$

this simplifies to

$\frac{100}{8}$

which is 12.5

Enter the slope of the line through the points (4 , 15) and (4 , 12)

pentagon [3]

Answer:

Step-by-step explanation:

slope m= (y2-y1) / (x2-x1) = 15-12 / 4-4 = 3/0 is undefined since we can not divide by 0

slope is undefined so the line is vertical

With replacement the sample space is:

(RR), (GG), (BB), (RG), (RB), (GR), (GB), (BR), (BG).

Without replacement you will not get 2 of the same colour, so it is

(RG), (RB), (GR), (GB), (BR), (BG).

Which expression is equivalent

Tatiana [17]

Given expression is

$\sqrt[4]{\frac{16x^{11}y^8}{81x^7y^6}}$

Radical is fourth root

first we simplify the terms inside the radical

$\frac{x^{11}}{x^7}=x^4$

$\frac{y^(8)}{y^6}=y^2$

So the expression becomes

$\sqrt[4]{\frac{16x^4y^2}{81}}$

Now we take fourth root

$\sqrt[4]{16} = 2$

$\sqrt[4]{81} = 3$

$\sqrt[4]{x^4} = x$

We cannot simplify fourth root (y^2)

After simplification , expression becomes

$\frac{2x\sqrt[4]{y^2}}{3}$

Answer is option B
