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)

11/8a+5/4a=18 cuanto es ?
aleksandr82 [10.1K]

Answer:

The Answer is: 47 1/4

Step-by-step explanation:

11/8a + 5/4a = 18

Create a common denominator for he coefficient of a:

11/8a + 2/2 * 5/4a = 18

11/8a + 10/8a = 18

21/8a = 18

Multiply both sides by the inverse of 21/8:

8/21 * 21/8a = 18 * 21/8

a = 378/8 or 189/4 or 47 1/4
