Let's check if (3 , 6) is the point of intersection of the given lines ~
and
If the point is the point of intersection of these two lines, then it should satisfy both the equations ~
let's try each of them, using x coordinate of point.
So, the point didn't actually satisfy one of the equation. hence we can infer that the given statement is wrong.
<span>2x^2 - 8x - 90
= 2 (x^2 - 4x - 45)
= 2 (x - 9)(x + 5)
so
x - 9 = 0; x = 9
x + 5 = 0; x = -5
solutions -5 and 9
answer

Step-by-step explanation:
Answer:
C: Permutation; Number of ways = 60
It is a permutation because the order matters of awarding the medals, therefore this problem is a permutation.
Solve this by:
5!/(5-3)!=60
