I know number 15 is right
Answer:
Q(2, 6 )
Step-by-step explanation:
Using the midpoint formula
let the coordinates of Q = (x, y ), then
0.5(x + 10) = 6 ( multiply both sides by 2 )
x + 10 = 12 ( subtract 10 from both sides )
x = 2
and
0.5(y + 6) = 6 ( multiply both sides by 2 )
y + 6 = 12 ( subtract 6 from both sides )
y = 6
Coordinates of Q = (2, 6 )

Answer: True</h3>
Reason:
The counting numbers, aka the set of natural numbers, is the set {1, 2, 3, 4, 5, ...} which is the set of positive integers
A value like 5 is the same as 5/1, which shows it is rational.
A rational number is any fraction of two whole numbers (eg: 2/3 and 4/7). The denominator cannot be zero.
Since we can rewrite the 5 as 5/1, it can be done with any counting number to show the natural numbers is a subset of the rational numbers.
Any counting number is rational, but not the other way around.
