Answer:
56
Step-by-step explanation:
If there can be only one 1 and only one 2, the remaining digits must all be 0. The digits 1 and 2 can be anywhere in the 8 digits, and can be in either order.
There are 8 possible locations in the sequence for the 1, then 7 possible locations for the 2. The total number of possibilities is 8·7 = 56.
12000000, 21000000, 10200000, 20100000, ..., 00000012, 00000021.
<span>to isolate y first step as follows;
5x - 7y - 10
-7y = -5x -10 (change the 5x to this side as negative)
</span><span>then divide by -7 and you have
-7y = -5x + 10
--- --- ---
-7 -7 -7
then you havd:
y = 5/7x -10/7</span>
