GEOMETRY 10TH GRADE NEED HELP ASAP

$\boxed{(6, -3)}$

Step-by-step explanation:

Given the ratio 5:3

and Points A and B where A is located at (-6, 3), and B is located at (26, -13).

Let point A be $(x_{1}, y_{1})$ , and let point B be $(x_{2}, y_{2})$ .

(-6, 3) → $(x_{1}, y_{1})$ .

(26, -13) → $(x_{2}, y_{2})$ .

Let 5 be n, and 3 be m.

5:3 → n:m

$(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m})$ .

To solve, just substitute these variables into the expressions of these coordinates to get the answer.

$(\frac{nx_{1} + mx_{2}}{n+m}, \frac{ny_{1} + my_{2}}{n + m})$ →

$(\frac{(5)x_{1} + (3)x_{2}}{(5)+(3)}, \frac{(5)y_{1} + (3)y_{2}}{(5) + (3)})$ →

$(\frac{(5)(-6)+ (3)(26)}{(5)+(3)}, \frac{(5)(3)+ (3)(-13)}{(5) + (3)})$ →

$(\frac{-30 + 78}{8}, \frac{15+ -39}{8})$ →

$(\frac{78 – 30}{8}, \frac{15 – 39}{8})$ →

$(\frac{48}{8}, \frac{-24}{8})$

→

$(\frac{6}{1}, \frac{-3}{1})$

→

$(6, -3)$ .

Thus the coordinates of B are:

$\boxed{(6, -3)}$

kumpel [21]

Answer:

answer b

Step-by-step explanation:

Answer b is definitely the correct one.

The Empirical Rule states that 68% of normally distributed data lies within 1 standard deviation of the mean; 95% within 2 standard deviations, and 99.9% within 3.
