Answer:

B.

Step-by-step explanation:

Because of isosceles triangle, AB = CB.

Because of the median, AD = CD.

Because of congruence of segments being reflexive, BD = BD.

By SSS, the triangles BAD and BCD are congruent.

Answer: B.

I need help solving. The answer is (2,-6)
faust18 [17]

Since we are given x in terms of y, the most efficient way to solve it would be to substitute in the \frac{1}{2}y+5 for x in the second equation. So, we then have:

2(\frac{y}{2}+5)+3y=-14 \implies \\
y+10+3y=-14 \implies \\
4y+10=-14 \implies\\
4y=-24 \implies \\
y=-6

So, now that we have our y, we can find x. We can actually use either equation, top or bottom, to find x, but to be efficient we should use the top one since we have x in terms of y, so:

x=\frac{-6}{2}+5 \implies \\
x=-3+5 \implies \\
x=2

So, our ordered pair is (2,-6).

What is the value of 7P5?<br><br> A.5040<br> B.2520<br> C.42<br> D.21
Marizza181 [45]
The answer is <span>B.2520
</span>
For permutation P we will use:
nPr = n!/(n-r)!
7P5 = ?
n = 7
r = 5
7P5 = 7!/(7-5)!
       = (7 * 6 * 5 * 4 * 3 * 2 * 1)/2!
       = 5040/(1 * 2)
       = 5040/2
       = 2520
