Three houses A B and Clie on the same line on a map. House Blies exactly in the middle of house A and house C The point (3,6) on

Svetlanka [38]

Answer:

(-13, -12)

Step-by-step explanation:

The midpoint (x,y) between two points ( $x_1,y_1$ ) and ( $x_2,y_2$ ) on the coordinate plane is given by:

$x=\frac{x_1+x_2}{2};\\\\y=\frac{y_1+y_2}{2}$

Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be ( $x_2,y_2$ ). Hence:

$-5=\frac{3+x_2}{2\\} \\3+x_2=-10\\\\x_2=-10-3\\\\x_2=-13$

$-3=\frac{6+y_2}{2\\} \\6+y_2=-6\\\\y_2=-6-6\\\\y_2=-12$

Therefore house C is at (-13, -12)

Dan made $5000 in taxable income last year.

storchak [24]

well, we know is 10% for the first 7500, but Dan only made 5000 of taxable income, so he's in that range of 0 - 7500, so he only gets to pay 10% of 5000.

$\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{10\% of 5000}}{\left( \cfrac{10}{100} \right)5000}\implies 500$
