Answer:
Given that,
Equation :y=2x+3
The point at which it cuts y-axis has x-coordinate as 0
∴y=2(0)+3=3
Hence, it cuts y-axis at (0,3)
Step-by-step explanation:
See,
If a + b + c = 0
Then,
a + b + c = 0
a + b = - c -- (I)
(a + b)^3 = (- c)^3
a^3 + b^3 + 3ab (a + b) = - c^3
from equation (I) a + b = - c
a^3 + b^3 + 3ab (- c) = - c^3
a^3 + b^3 - 3abc = - c^3
a^3 + b^3 + c^3 = 3abc
Hence,
a^3 + b^3 + c^3 ‘not equal’ 0
but,
a^3 + b^3 + c^3 ‘equal’ 3abc
