Answer:
y : x: = 5 : 4
Step-by-step explanation:
x to y = 4 to 5
Rewrite;
x:y = 4:5
Remember, a ratio is another way of representing a fraction, hence one can do the same operations that one could do with a fraction. Therefore, one can take the cross products of a ratio;
x : y= 4 : 5
5x = 4y
Inverse operations;
5x = 4y
x = 
y
Now substitute this into the equation y:x
y : y
Rewrite as a fraction;
Simplify;
Rewrite as a ratio;
y : x = 5 : 4

1) -2《3 - 3
-2《0
-2》-3 - 2
-2》-5
2) 4 > -3 + 3
4 > 0
4 > 1 + 2
4 > 3
3) -2《0 - 6
-2《-6 is false
4) 0 - 3 < 4
-3 < 4
0 + 3 > -1
3 > -1
5) 0 > -6 - 3
0 > -9
0 < 3 + 6
0 < 9

Greetings from Brasil...
Solving the inverses of these functions and applying the composite we obtain:
(G⁻¹ о F⁻¹) = X
Note that (F⁻¹ о G⁻¹) also results in X (see second annex)
