Answer:

\left(\displaystyle -\frac{2}{5},\frac{4}{5}\right)

Step-by-step explanation:

<u>Proportions</u>

The coordinates of the point R are (-6,4) and the coordinates of the point S are (8,-4). We must find the coordinates of a point P(x,y) such that the ratio of segment RP to segment PS is 2/3. Let's find the coordinates separately. In the x-axis:

\displaystyle \frac{-6-x}{x-8}=\frac{2}{3}

Operating and rearranging

-18-3x=2x-16

Solving

\displaystyle x=-\frac{2}{5}

Now for the y-axis

\displaystyle \frac{4-y}{y+4}=\frac{2}{3}

Operating and rearranging

12-3y=2y+8

Solving

\displaystyle y=\frac{4}{5}

Thus, the point that partitions the segment in the ratio 2 to 3 is

\left(\displaystyle -\frac{2}{5},\frac{4}{5}\right)

Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, squ
Dahasolnce [82]

Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
