What is the coordinate of point P that lies along the directed line segment from Q(2, 5) to R(7, 12) and partitions the segment

Wittaler [7]

Answer:

Option (3). (5, 9.2)

Step-by-step explanation:

If Point P divides the line segment QR in the ratio of m : n.

Let the coordinates of the point P are (x, y)

Since coordinates of the point P are given by,

x = $\frac{m(x_2)+n(x_1)}{m+n}$

y = $\frac{m(y_2)+n(y_1)}{m+n}$

Where $(x_1, y_1)$ and $(x_2,y_2)$ are the ordered pairs representing points Q and R.

If $(x_1,y_1)$ represents (2, 5) and $(x_2,y_2)$ represents (7, 12),

Coordinates of point P(x, y) which divides the segment in the ratio of 3:2.

x = $\frac{3(7)+2(2)}{3+2}$

x = $\frac{25}{5}=5$

y = $\frac{3(12)+2(5)}{3+2}$

y = $\frac{46}{5}=9.2$

Therefore, Point P will be represented by (5, 9.2)

Option (3) will be the answer.

Answer:

A) 5x+12 = -12x-12

D) 5x+12 = -5x-12

Step-by-step explanation:

If you subtract the right side expression from both sides, you will get an equation with something equal to zero. If the 'something' has a variable in it, there is exactly one solution.

A: (5x+12) -(-12x-12) = 17x+24 = 0 . . . one solution

B: (5x+12) -(5x-5) = 17 = 0 . . . . no solutions

C: (5x+12)-(5x+12) = 0 = 0 . . . . infinite solutions

D: (5x+12) -(-5x-12) = 10x +24 = 0 . . . one solution
