(GEOMETRY PLS HELP SERIOUSLY) A treasure map says that a treasure is buried so that it partitions the distance between a rock an

You have coordinates of tree T(16,21) and of rock R(3,2). Let S be a point that denotes treasure. Since treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio, you can state that

$\dfrac{\overrightarrow{RS}}{\overrightarrow{ST}}=\dfrac{5}{9}.$

Find the coordinates of these vectors:

$\overrightarrow{RS}=(x_S-3,y_S-2), \\
\overrightarrow{ST}=(16-x_S,21-y_S).$

Then

$\dfrac{x_S-3}{16-x_S} =\dfrac{5}{9}$ and $\dfrac{y_S-2}{21-y_S} =\dfrac{5}{9}.$

Solve these two equations:

$9(x_S-3)=5(16-x_S),\\ 9x_S-27=80-5x_S,\\ 9x_S+5x_S=80+27,\\14x_S=107,\\ \\x_S=\dfrac{107}{14}\approx 7.6.$

$9(y_S-2)=5(21-y_S),\\9y_S-18=105-5y_S,\\9y_S+5y_S=105+18,\\14y_S=123,\\ \\y_S=\dfrac{123}{14}\approx 8.8.$

Answer: the treasure are placed at point (7.6,8.8), so the correct choice is B.

I solved using brainly but i need to show my work what are the steps in solving please

Answer:

Step-by-step explanation:

to find the inverse first switch the x and y

y=log(x+3) inverse is x=log(y+3)

then change to exponential form to solve

$log_{a} b=c$ turns to $a^{c}=b$

a is 10

b is y+3

c is x

$10^{x} =y+3$ subtract 3 from both sides

$10^{x} -3=y$
