Answer:
Step-by-step explanation:
The true statement is (c) No; the slopes of segment EF and segment DF are not opposite reciprocals.
<h3>
Right triangles </h3>
Right triangles have a pair of perpendicular lines
Coordinates
The coordinates are given as:
- D = (-2,-1)
- E = (-2,2)
- F = (0,0)
<h3>Slopes</h3>
Start by calculating the slopes of lines DF and EF using:

So, we have:


Also, we have:



For the triangle to be a right triangle, then the calculated slopes must be opposite reciprocals.
i.e.

By comparison, the slopes of both lines are not opposite reciprocals.
Hence, the true statement is (c)

<span>I will discuss polynomials. A polynomial can be
classified according to the number of expressions that it has in a given
equation. A monomial has only one expression having a coefficient (number) and
a variable (letter). A binomial has two expressions, same as the definition of
the monomial. And a trinomial has three expressions, same as the definition of
a monomial. We can determine the degree of a polynomial by looking at the
exponents of the given polynomial. If an expression has two variables with
different exponents, you can add their exponent to determine their degree.
