Answer:
c) {(1,3), (2, 4), (1, 4), (2,3)}
Step-by-step explanation:
Since, the cartesian product of two sets A and B is defined as,
A × B = {(a, b) : a ∈ A and b ∈ B},
Here, the given sets,
A = {1, 2},
B = {3, 4}
Thus, by the above definition,
A × B = { (1, 3), (1, 4), (2, 3), (2, 4) }
Hence, option 'c' is correct.
Answer: Step-by-step explanation:
57 - 10x = 45
-10x=-12
x=1.2
- 3y + 10x = -5
-3y+10=-5
-3y=-15
y=5
