castortr0y [4]

If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:

15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58

$43.89 - $6.58 = $37.31

5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87

$37.31 - $1.87 = $35.44

The correct result would be <span>$35.44.</span>

A line that passes through the points (–4, 10) and (–1, 5) can be represented by the equation y = (x – 2). Which equations also

lyudmila [28]

The equation y=x-2 do not represents the line that passes through the two point, since for example -4-2=-6, not 10. So (-4,10) is not on the line.
Let find the equation of the line:
First compute the slope using formula:
<span> </span> $\frac{y_2-y_1}{x_2-x_1}= \frac{5-10}{-1-(-4)}= \frac{-5}{3}$
So the equation is in the form:
$y=\frac{-5}{3}x+s\text{ wherein s is another parameter. }$
For x=-4 we get the equation:
$10=\frac{-5}{3}(-4)+s$
Solving the above equation for s we get:
$s= \frac{10}{3}$
The equation then is the following:
$y=\frac{-5}{3}x+\frac{10}{3}$

The correct answer then is equation 2 and equation 3.
