ANSWER
Yes it is very true
<u>EXPLANATION</u>
If the two equations intersect at
then this point must satisfy the two equations.

We substitute
in to erquation (1)




We now substitute
in to erquation (2) also



Since the point satisfy all the two equations, it is true that they intersect at 
Answer: =x2−3x−54
Step-by-step explanation:
Answer:
k = -2
Step-by-step explanation:
f(x) = (x − h)² + k
(h, k) is the (x, y) coordinate of the vertex
For a vertex of (4, -2)
h = 4
k = -2
