Answer:

$Average\:Rate\:Change=-59.4$

Step-by-step explanation:

The given function is $f(x)=120(0.1)^x$ .

We want to find the average rate of change of this function from $x=0$ to $x=2$ .

This is given by:

$Average\:Rate\:Change=\frac{f(2)-f(0)}{2-0}$

This implies that;

$Average\:Rate\:Change=\frac{120(0.1)^2-120(0.1)^0}{2-0}$

$Average\:Rate\:Change=\frac{120(0.1)^2-120}{2}$

$Average\:Rate\:Change=\frac{120((0.1)^2-1)}{2}$

$Average\:Rate\:Change=\frac{60(0.01-1)}{1}$

$Average\:Rate\:Change=60(-0.99)$

$Average\:Rate\:Change=-59.4$

I need help on doing the equal values method. Please tell me how to do y=11-2x y=x+2

noname [10]

Answer:

11-2x=x+2

-3x=9

x=-3

Step-by-step explanation:

y=11-2x

y=x+2

So we use the first equation to plug in for the second equation.

Then we solve for x and get the answer. Hope this helps. Thank you.
