What is the sum of 15 – 6i and –2 + 9i?

Sum is 13 +3i .

Step-by-step explanation:

Given  :15 – 6i and –2 + 9i

To find :What is the sum

Solution : We have given 15 – 6i and –2 + 9i

On adding the terms

15 – 6i + (–2 + 9i)

15 – 6i –2 + 9i

On combine real part and complex part.

15 -2 - 6i + 9i.

13 +3i

Therefore, Sum is 13 +3i .

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
