If

, then there is some integer

such that

. Because

, it follows that

, which means there is some integer

such that

, which is equivalent to the statement that

.
In finding the value of this inequality first is to substitute the X to the F(x) so that it would be rearrange to get the value of k. So if 3<=x, K is directly proportional to X so it means that K >=3
Not quite sure what you’re asking for but i can offer a couple(and by that i mean two) “answers” depending on what you need.
Usd>Yen~1->.009
Gym B costs 50%less
If the question is trying to compare hours to usd then Gym A is the most accurate representation of USD to Yen
The opposite of 1 is -1 :)
Solve both formulas to y=mx+b (slope intercept formula) where m=slope and b=y-intercept
y=-3/1x+-7
x-2y=-14
-2y=-14-x
y=7+1/2x
Start with the b variable so for problem 1 put a dot on 0,-7 and for problem 2 put a dot on 0,7
Then from -7 for problem 1 depending on whether the slope is negative or positive go down 3 and over right 1 therefore another point for problem one is marked, at 1,-10; for problem 2 up 1 and to the right 2; 2,8
For problem one connect the dots of 0,-7 and 1,-10
For problem two connect the dots of 0,7 and 2,8
