How do I find the endpoint of a segment when given the first endpoint (-6, 5) and the midpoint(-1.5, 1)?​
Anika [276]

Answer:

(3, -3)

Step-by-step explanation:

Use the midpoint formula.

x = (x₁ + x₂) / 2

-1.5 = (-6 + x) / 2

-3 = -6 + x

x = 3

y = (y₁ + y₂) / 2

1 = (5 + y) / 2

2 = 5 + y

y = -3

The other endpoint is (3, -3).

Compare the fraction 1:24,000 to the fraction 1:3,168,000; which is the largest rational number
gulaghasi [49]

Answer:

\frac{1}{24,000}

Step-by-step explanation:

we know that

When we compare positive fractions with the same numerator, the largest rational number will be the fraction with the lowest denominator

In this problem we have

\frac{1}{24,000}  and   \frac{1}{3,168,000}

Both numerator are equal

Compare the denominators

24,000 < 3,168,000

therefore

\frac{1}{24,000}  is the largest rational number
