Point E is located at (2, −3), and point F is located at (−2, −1). Find the y-value for the point that is 3 over 4 the distance
12345 [234]

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length. The<em> y</em> value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

Given information-

The coordinates of the point E is (2,-3).

the coordinates of the point F is (-2,-1).

As the 3/4 the distance from the point E is the point F is means the points which divides the line EF in the ratio of 3/1.

<h3>Ratio of two point</h3>

The ratio of the two point is the coordinate at the plane where the two point are divided at the fixed amount of length.

Suppose the ratio m:l are the ratio of the two points (x_1,y_1) and (x_2,y_2). Then the coordinate of the point which divide the line at this ratio can be given as,

(x,y)=\left ( \dfrac{mx_2+lx_1\tiems}{m+l} ,\dfrac{my_2+ly_1}{m+l}  \right )

Put the values,

(x,y)=\left ( \dfrac{3\times (-2)+1\times(2)}{3+1} ,\dfrac{3\times (-1)+1\times(-3)}{3+1}  \right )

(x,y)=(-1,-1.5)

Thus the<em> y</em> value of the point that is 3/4 distance from point E to point F is -1.5. thus the option 4 is the correct option.

Find the sum. r/r^2-q^2 + 5/r+q​
pickupchik [31]

Answer:

The answer is:  

\frac{6r-5q}{r^2-q^2}

which agrees with the last answer option (D) in the list.

Step-by-step explanation:

In order to add rational expressions, we need to express them with the same denominator. Therefore we examine what factors there are in the first denominator, which happens to be a difference of squares which is readily factored out as:

r^2-q^2=(r+q)\,(r-q)

the second denominator consists of only one of these factors: (r+q), then in order to express both rational expressions with the same common denominator, we multiply numerator and denominator of the second fraction by the factor: (r-q)

Then we get two expressions that can be easily added as shown below:

\frac{r}{(r+q)\,(r-q)} +\frac{5\,(r-q)}{(r+q)\,(r-q)} =\frac{r+5(r-q)}{(r+q)(r-q)} =\frac{r+5r-5q}{(r+q)\,(r-q)} =\frac{6r-5q}{r^2-q^2}
