Answer:
4
Step-by-step explanation:
Given:
A, B, C, D have distinct positive values for mod 6
A (mod 6) = 1
B (mod 6) = 2
C (mod 6) = 4
D (mod 6) = 5
Each mod 6 value cannot be a zero since the product ABCD is not a multiple of 6.
Furthermore, in order that ABCD mod 6 > 0, we cannot have a residue equal to 3, else the product with a residue 2 or 4 will make the product a multiple of 6.
Thus the only positive residues can only be 1,2,4,5
A*B*C*D (mod 6) > 0 = 1*2*4*5 (mod 6) = 4
Answer:
Step-by-step explanation:
- <em>Period is the distance between two consecutive maximum points, or two consecutive minimum points.</em>
<u>On the given graph the period is the distance between maximum points -7 and 3:</u>
Answer:
Step-by-step explanation:
if you multiply 2 to both sides, 2(3x+2y)=2*3, having 6x+4y=6
thus, the two equations are same (consistent), having infinite number of solutions (dependent).
