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;

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

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

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

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

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

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

Could someone break it down. I am not catching on.

$\bf -0.04y+0.11(9000-y)=0.35y
\\\\\\
-0.04y+990-0.11y=0.35y
\\\\\\
990-0.15y=0.35y\implies 990=0.35y+0.15y
\\\\\\
990=0.50y
\implies 
\cfrac{990}{0.5}=y\implies 1980=y$

Answer:

x = 2

Step-by-step explanation:

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we divided by 2 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

→ Expand the brackets

$\frac{1}{2} x- \frac{1}{2}-\frac{1}{6}x -\frac{1}{6} =0$
