Answer:

When $p^2 - 4p$ is subtracted from $p^2 + p - 6$ , the result is $5p - 6$ . To get $p - 9$ , subtract $4p + 3$ from the result.

Step-by-step explanation:

✔️Subtracting $p^2 - 4p$ from $p^2 + p - 6$ :

$(p^2 + p - 6) - (p^2 - 4p)$

$p^2 + p - 6 - p^2 + 4p$ (Distributive property)

Collect like terms

$p^2 - p^2 + p + 4p - 6$

$5p - 6$

✔️Subtracting $p - 9$ from $5p - 6$ :

$(5p - 6) - (p - 9)$

$5p - 6 - p + 9$ (distributive property)

Add like terms

$4p + 3$

Rate of change of rational functions

densk [106]

Answer:

0.635

Step-by-step explanation:

$rate~of~change = \dfrac{f(x_2) - f(x1)}{x_2 - x_1}$

$rate~of~change = \dfrac{f(x_2) - f(x1)}{x_2 - x_1}$

$x_1 = 0$ $x_2 = 0.3$

$f(x) = \dfrac{-7x^3}{x^4 - 1}$

$f(x_1) = f(0) = \dfrac{-7(0)^3}{(0)^4 - 1}$

$f(x_1) = \dfrac{0}{-1} = 0$

$f(x_2) = f(0.3) = \dfrac{-7(0.3)^3}{(0.3)^4 - 1}$

$f(x_2) = \dfrac{-0.189}{-0.9919} = 0.190543$

$rate~of~change = \dfrac{0.190543 - 0}{0.3 - 0} = 0.635$

I WILL GIVE BRAINLIEST AND 50 POINTSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

mars1129 [50]

Answer:

we get Rate of change = -3

Step-by-step explanation:

We need to calculate the rate of change for the following data:

x y

-1 7

2 -2

7 -17

10 -26

The rate of change can be calculated using slope formula: $Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}$

From the table, we can take any 2 points

Suppose we take (-1,7) and (2,-2)

We have: $x_1=-1, y_1=7,x_2=2, y_2=-2$

Putting values in formula and finding rate of change

$Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:change=\frac{-2-7}{2-(-1)}\\Rate\:of\:change=\frac{-9}{2+1}\\Rate\:of\:change=\frac{-9}{3}\\Rate\:of\:change=-3$

So, we get Rate of change = -3
