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;

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

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

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

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

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

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

What is the value of x in the equation -6/7= -×/84?

pantera1 [17]

-6/7 = -x/84

84/7 = 12

12(-6) = -72

x = -72

So, -6/7 = -72/84 because -72/84 simplifies to -6/7
