Answer:

$0.42

Step-by-step explanation:

Look at the function definition to see which part applies when x = 0.4. It will be the first part, which is defined for 0 < x < 1. That part tells you the postage for 0.4 oz is $0.42.

Solnce55 [7]

To work out percentage, divide what they've done (21) by the total distance (50), then multiply it by 100 to get the percentage
(21/50)*100 = 42%

What is the equation of this graphed line?

valkas [14]

Let's start by simply using two points from the line hmmmmm wait a second, low and behold, there are two there already labeled, so, let's use those ones then,

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 0}}\quad ,&{{ 7}})\quad 
% (c,d)
&({{ 8}}\quad ,&{{ -2}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-2-7}{8-0}\implies \cfrac{-9}{8}$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-7=-\cfrac{9}{8}(x-0)\implies y-7=-\cfrac{9}{8}x
\\\\\\
y=-\cfrac{9}{8}x+7$
