Answer:
x = 0
y = 3
Step-by-step explanation:
6x + 2y = 6 | ×7 |
7x + 3y = 9 | ×6 |
42x + 14y = 42
42x + 18y = 54
____________--
-4y = -12
y = -12/-4
y = 3
6x + 2y = 6
6x + 2(3) = 6
6x + 6 = 6
6x = 6 - 6
6x = 0
x = 0/6
x = 0
Answer:
f(x) = x^2 (x + 7i)(x - 7i)
Step-by-step explanation:
Factoring out x^2 gives ...
f(x) = x^2(x^2 +49)
The factor with 49 can be considered to be the difference of two squares, where one of the squares is -49. Then its square root is ±7i, and the factorization of that term is ...
x^2 +49 = (x +7i)(x -7i)
So, the overall factorization of f(x) is ...
f(x) = x^2(x +7i)(x -7i)
It is 3.
You can check this by seeing 3^3 ie. 3x3x3, which comes out as 27.
You can check the cube root on a calculator.
