Answer:

2nd one

Step-by-step explanation:

x(2) + 2 = 420

you can use trial and error

210(2) = 420 but we need to add the two so lower the 120

209(2) = 418  418 + 2 = 420

What is the average rate of change over the interval (-1, 5)​
MArishka [77]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete as the function is not given. However, the following explanation will guide you.</em>

<em></em>

The average rate of change is calculated using;

A = \frac{f(b) - f(a)}{b - a}

Where

(a,b) = (-1,5)

Take for instance;

The function is:

f(x) = 2x

We have to solve for f(-1) and f(5);

i.e.

f(-1) = 2 * -1  -2

f(5) = 2 * 5 = 10

Substitute -1 for a and 5 for b

A = \frac{f(b) - f(a)}{b - a}

A = \frac{f(5) - f(-1)}{5 - (-1)}

A = \frac{f(5) - f(-1)}{5 +1)}

A = \frac{f(5) - f(-1)}{6}

Substitute values for f(5) and f(-1)

A = \frac{10 - (-2)}{6}

A = \frac{10 +2}{6}

A = \frac{12}{6}

A = 2

then multiply by 5

that should give you the original price of the bean bag chair!
