Answer:
x=3, y=2
Step-by-step explanation:
To solve by elimination method, multiply one of the equation by a constant such that when you subtract one equation from the other, you are left with one term only.
As x increases, f(x) decreases. As x decreases, f(x) decreases
Since we can't use a zero at the start and end, then we have 810 different ways.
If we can't have a leading digit of zero, then we still have 9 available digits to choose from (9P1)
Now, the second term can be of any number, so we will have 10 different digits to choose 1 (10P1)
Now, the final term cannot be a zero, so we will have 9 available digits to choose from (9P1)
Hence, our final number of ways is: 9 × 10 × 9 = 810 ways.
