Find the midpoint of (5,9) and (-1,9)

777dan777 [17]

Answer:

The answer to your question is (2, 9)

Step-by-step explanation:

Data

A (5, 9)

B (-1, 9)

Formula

Xm = $\frac{1 + x2}{2}$

Ym = $\frac{y1 + y2}{2}$

Substitution

Xm = $\frac{5 - 1}{2}$

Xm = $\frac{4}{2} = 2$

Ym = $\frac{9 + 9}{2} = \frac{18}{2} = 9$

Midpoint = (2, 9)

Starting at home, Luis traveled uphill to the gift store for 50 minutes at just 6 mph. He then traveled back home along the same

Orlov [11]

Let S = his average speed.

Let D = distance traveled one way

Time = distance / speed

Set up an equation:

d/6 + d/12 = 2d/S

Multiply the equation by 12s:

12s(d/6) + 12s(d/12) = 12s(2d/s)

Simplify to get:

2sd + sd = 24d

Combine like terms:

3sd = 24d

Divide both sides by d:

3s = 24

Divide both sides by 3:

s = 24/3

s = 8

His average speed was 8 mph.
