The equation you are looking for is x + 5 = 0. To solve for x, you would subtract 5 from both sides of the equation. This would give you x = -5. Therefore, -5 plus 5 equals 0.
6y - 5 = -5; so 6y = -5 + 5; so 6y = 0; so y = 0
X should be zeroas:X + 5 = 2X + 5so, 2X - X = 0 or X = 0

6y - 5 = -5; so 6y = -5 + 5; so 6y = 0; so y = 0
x = 12
X should be zeroas:X + 5 = 2X + 5so, 2X - X = 0 or X = 0
2x2-x-15 = 0 When factorised: (2x+5)(x-3) = 0

10 to the 0 power is 10 and 5 to the 0 power is 5 so 10 multiplied by 5 equals 50.
5x2-2x = 0 x(5x-2) = 0 Therefore: x = 0 or x = 2/5
5 raised to the power 3 equals 5 x 5 x 5 = 125 a to the power of 3 equals a x a x a zero to the power 3 = 0 x 0 x 0 = 0 zero to the power 10 = 0 x 0 x 0 x 0 x 0 x 0 x 0 x 0 x 0 x 0 = 0 So you can see that no matter how many times we multiply zero by itself the answer is always zero. Hence zero raised to the power zero equals zero
correct anser is C ; y=-45
X = 0 (zero) Y = -1 (neg 1)
