Answer:
10 is the answer
Step-by-step explanation:
C(5,2) = 5! / 2! (5-2)!
C(5,2) = 5! / 2!3!
C(5,2) = 120/12
C(5,2) = 10
Answer:
y=2x squared -3x-62
Step-by-step explanation:
Answer:
The answer to your question is: x = -1
Step-by-step explanation:
Data
slope of l = x
slope of m = x +2
they are ⊥
Process
If they are ⊥, then, x + 2 = - 1/x
x(x + 2) = -1
x² + 2x = -1
x² + 2x + 1 = 0
(x + 1)² = 0
x + 1 = 0
x = -1
Answer:
