Answer:
352
Step-by-step explanation:
originally 351.86 but 352 when rounded
If given the equation, you need to take the number beside the x and y and change their signs to get your point:
x - 8 (Take the -8 and make it +8)
y + 2 (Take the +2 and make it -2)
Your point is (8, -2)
Answer:
See explanation below
Step-by-step explanation:
If x is even, then we know that x = 2k for a k ≥1
If y is odd, then we know that y = 2j -1 for a j≥1
Therefore, x + y can be written similarly as:


And clearly, 2(k + j) -1 is odd.
Therefore, the sum x + y is an odd number.
