Ten times the sum of half a number and 6 is 8

vredina [299]

Ten (10) times (multiplication) the sum (addition) of half ( $\frac{1}{2}$ a number (n) and 6 is (=) 8.

10( $\frac{n}{2}$ + 6) = 8 Use the Distributive Property
5n + 60 = 8 Subtract 60 from both sides
5n = -52 Divide both sides by 5
n = -10 $\frac{2}{5}$

Calculate the average rate of change for the given function, from x = 2 to x = 7.

Marina86 [1]

$\bf slope = m = \cfrac{rise}{run} \implies 
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby 
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\

\begin{array}{ccll}
x&f(x)\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
-2&0\\2&15\\7&30
\end{array}
\qquad 
\begin{cases}
x_1=2\\
x_2=7
\end{cases}\implies \cfrac{f(7)-f(2)}{7-2}\implies \cfrac{30-15}{5}
\\\\\\
\cfrac{15}{5}\implies 3$
