Answer:
$6.83
Step-by-step explanation:
First calculate the before-tax total amount:
$0.75 + $0.75 + $0.75 + $4.25, or
3($0.75) + $4.25 = $2.25 + $4.25 = $6.50 (total before tax)
The before-tax total PLUS the 5% tax comes to:
$6.50 + 0.05($6.50) = $6.50 + $0.33 = $6.83
The piecewise-defined function with linear parts f(x)= |2x + 9|
f(x) = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
<h3>How to write piecewise functions?</h3>
To write this function as a piecewise function, you have to use the definition of absolute value.
The absolute value equation is; f(x)= |2x + 9|
The definition says that;
|x| = {x x ≥ 0)
{-x x < 0}
Applying this definition to the function you get:
|2x + 9| = {2x + 9 2x + 9 ≥ 0)
{-2x - 9 2x + 9 < 0}
After simplifying the inequalities you get:
|2x + 9| = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
So finally you can write the piecewise function as:
f(x) = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
