FIrst, list all the factors of 42 (positive integers):
________________________________________________________
1, 42
2, 21,
3, 14,
6, 7
_________________________________________________
Then list all the factors of 28 (positive integers):
____________________________________________________
<span> 1, 28
2, 14,
4, 7
</span>_____________________________________________________
Now, list all numbers that occur for BOTH the factors of "28" AND the factors of "42"
_____________________________________________________
1, 2, 7, 14
_____________________________________________________
The answer is: 1, 2, 7, 14 .

so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.
Answer:
The answer is that x = 0 and y = -6. While this is not any of your options, the work below proves that it is correct.
In order to find these values, we can use elimination. To do so, we multiply the first equation by 5 and then add the equations together.
125x - 5y = 30
-2x + 5y = -30
------------------
123x = 0
x = 0
Now that we have this value, we can plug the value into one of the originals and find y.
25x - y = 6
25(0) - y = 6
-y = 6
y = -6
The inverse of f does NOT exist. The reason why is because the function fails the horizontal line test. Recall that the horizontal line test is a test where you try to see if you can pass a single horizontal line through more than one point on the function curve. If you can get the horizontal line to pass through more than one point, then it fails the test. It's very similar to the vertical line test.
