I would reccomend the app photo math its really easy to use and it answers questions like this.
Answer:
2 - 8i
Step-by-step explanation:
The additive inverse of something is basically the opposite of it. Another way to say this is that when you add the additive inverse to -2 + 8i, it will equal 0.
<u>An example:</u>
The additive inverse of 7 is -7 because not only is it the opposite, but also when you add 7 and -7, it equals 0.
<u>To solve</u>
So all you need to do is find the opposite of -2 + 8i. You can write it as:
-(-2 + 8i) With the negative in the front because we want to find the opposite.
This then equals:
2 - 8i
You can check your answer by adding -2 + 8i and 2 - 8i to see if it equals 0:
(-2 + 8i) + (2 - 8i) → and it does equal 0
<u>ANSWER:</u> 2 - 8i
Hope you understand and that this helps with your question! :)
The answer would be 57 with a remainder of 7.
Answer:
x=9, y=0. (9, 0).
Step-by-step explanation:
y=-3x+27
6y-x+9=0
-----------------
6(-3x+27)-x+9=0
-18x+162-x+9=0
-19x+171=0
-19x=0-171
-19x=-171
19x=171
x=171/19
x=9
y=-3(9)+27=-27+27=0
