Find the coordinates for the midpoint of the segment with endpoints give (3,5) and (-2,0)
Leto [7]

Answer:

The coordinates of the mid-point are :

(\frac{1}{2}, \frac{5}{2})

Step-by-step explanation:

We know that, the coordinates of the mid-point (<em>x</em>, <em>y</em>) of a line segment joining the points (<em>x</em>₁, <em>y</em>₁) and (<em>x</em>₂, <em>y</em>₂) is given by

(x, y) = (\frac{x_{1} +x_{2} }{2},\frac{y_{1}+y_{2} }{2} )

Now, we have the given points as (3, 5) and (-2, 0).

By using the above formula, coordinates of the mid-point (<em>x</em>, <em>y</em>) of the line-segment joining the points (3, 5) and (-2, 0) is given by,

x = \frac{3+(-2)}{2} = \frac{3-2}{2} = \frac{1}{2}

y = \frac{5+0}{2} = \frac{5}{2}

∴ coordinates of the mid-point of the line-segment joining the points (3,5) and (-2,0) is (\frac{1}{2}, \frac{5}{2}).

Solve the equation -6(2a + 7) = -22- 8a
Andru [333]

Answer: a = -5

Step-by-step explanation:

First, open up the brackets, and solve it

-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)

bring the -8a to the left side, so that all the a’s are together

-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)

-12a + 8a = -22 + 42

solve

-4a = 20

divide -4 on both sides

a = -5

Find the distance between the points (2, 8) and (-1, 9).
klemol [59]
Distance = √(x2-x1)² + (y2-y1)²
= √(2+1)² + (8-9)²
= √3² + (-1²)
=  √ 3+1
= √4
= 2

In short, Your Answer would be 2 units

Hope this helps!
