murzikaleks [220]3 years ago
3 0

Answer:

The correct complex numbers would be, -2 - 4i and 2 + 2i

(−2 − 4i) − (2 + 2i) = -4 - 6i

Step-by-step explanation:

(−2 − 4i) − (2 + 2i)

Subtract 2 + 2i from −2 − 4i by subtracting corresponding real and imaginary parts.

−2 − 2 + (−4 − 2)i

Subtract 2 from −2. Subtract 2 from −4.

-4 - 6i

So, the correct complex numbers would be, -2 - 4i and 2 + 2i

F(x) = 9-3x<br> g(x) = 5x-7<br> Find f(x)+g(x).
Bezzdna [24]

Answer:

In the problem, the sum of the two functions is 2x + 2

Step-by-step explanation:

For this problem, we have to add together f(x) and g(x).

<em>f(x) = 9 - 3x</em>

<em>g(x) = 5x - 7</em>

(f + g)(x) = (9 - 3x) + (5x - 7)

Combine like terms.

(f + g)(x) = 2x + 2

So, when you combine the two functions together, you will get 2x + 2.
