What are the coordinates of the point in the directed line segment from (-2,-8) to (5,-1) that partitions the segment into the r
boyakko [2]

Answer:

The coordinates of the point X:

  • (x, y) = (-1, -7)

Step-by-step explanation:

Let X be the point.

As the point X is in the directed line segment from (-2,-8) to (5,-1) into the ratio of 1 to 6

i.e.

\left(x_1,\:y_1\right)\:=\:\left(-2,-8\right)

\left(x_2,\:y_2\right)=\left(5,-1\right)

Rise = y₂ - y₁

       = -1 - (-8)

       = -1 + 8

       = 7

Run = x₂ - x₁

      = 5 - (-2)

      = 5 + 2

      = 7

1 : 6 ratio means the point X lies at

\frac{1}{6+1}=\frac{1}{7}=14\%

Thus,

rise for X =\:7\:\times \:14\%=1

run for X =\:7\:\times \:14\%=1

Thus, coordinates of X will be:

x = -2 + 1 = -1

y = -8 + 1 = -7

Therefore, we conclude that:

The coordinates of the point X:

  • (x, y) = (-1, -7)

Step-by-step explanation:

y=mx+b

slope =

1--3/3-4

4/-1

-4/1

y-1=-4(x-3)

y-1=-4x+12

y=-4x+13

If this first answers correct what is the answer to the second question? Are they even connected?
vlabodo [156]

Answer:

see below (I hope this helps!)

Step-by-step explanation:

9) We know that the perimeters of the square and triangle are equal so to find x, we can write:

4(x - 5) = x + x + 12

4x - 20 = 2x + 12

2x = 32

x = 16

10) To find the perimeter, we can substitute x = 16 into 4(x - 5) which would be 4(16 - 5) = 4 * 11 = 44.
