Answer:
no
Step-by-step explanation:
If this were a right triangle we would assume the Pythagorean Theorem to prove it


this gives us
49+64=84.64
this is 143=84.64 and therefore not equal and not a right triangle
Answer: A: the range of F(x) isY>0 C : The y-intercept is (0,1) E. It is decreasing.
Step-by-step explanation:
Answer:
D(-2, 5).
Step-by-step explanation:
We are given that M is the midpoint of CD and that C = (10, -5) and M = (4, 0).
And we want to determine the coordinates of D.
Recall that the midpoint is given by:

Let C(10, -5) be (<em>x</em>₁<em>, y</em>₁) and Point D be (<em>x</em>₂<em>, y</em>₂). The midpoint M is (4, 0). Hence:

This yields two equations:

Solve for each:

And:

In conclusion, Point<em> </em>D = (-2, 5).
