This is subtraction property of equality.
Answer:B)
Answer:
is not a rectangle
Step-by-step explanation:
The midpoints of the diagonals are ...
AC midpoint = ((2, -2) +(11, 13))/2 = (13/2, 11/2)
BD midpoint = ((14, 10) +(-2, 1))/2 = (6, 11/2)
The midpoints of the diagonals are different, so this is not a rectangle or any sort of parallelogram.
Answer:
BC = 10
Step-by-step explanation:
BC = BD - CD
BC = 14 - 4
BC = 10
Given:
The function is:

To find:
The domain of the given function.
Solution:
Domain is the set of input values.
We have,

It is a quadratic polynomial.
We know that a quadratic polynomial is defined for all real values of x. So, the given function is defined for all real values of x and the domain of the given function is:
Domain = Set of all real number
Domain = (-∞,∞)
Therefore, the correct option is B.
