The additive inverse of a number gives zero. The additive inverse of the complex number -8+3i is 8-3i.
<h3>What is additive inverse?</h3>
The additive inverse of a number is the other number which when added to the initial number gives the output as zero.
As we know about the additive inverse, therefore, we need a number that will return zero when added to the complex number.
The additive inverse of the complex number -8+3i will be,
Thus, the additive inverse of the complex number -8+3i is 8-3i.

Answer:
D, 4
Step-by-step explanation:
The graph crosses the x-axis 4 different times
Answer:
=468 m^2
Step-by-step explanation:
Surface area of a prism is
SA = 2 (lw + wh + hl) where l is length, w is width and h is height
SA = 2 ( 12*6 + 6*9 + 9*12)
= 2 ( 72+54+108)
= 2(234)
=468 m^2
Basically, this problem is saying that if you multiply x by 3, then you will get a number that is one less than y. So, if you switch that around a bit, then the problem is saying that if you subtract 3x from y, you'll get 1.
Your final answer should be y - 3x = 1.

Step-by-step explanation:
→ First understand what Pythagoras theorem is
Pythagoras is a theorem used to find the hypotenuse (the side opposite to the right-angle) of a triangle. We would need the base lengths as well the height in order to use Pythagoras.
→ State the formula and identify the letters
a² + b² = c² ⇒ where 'a' is 380cm, 'b' is 290cm and 'c' is what we are trying to work out
→ Substitute in the values into the formula
380² + 290² = c²
⇒ Simplify
144400 + 84100 = c²
⇒ Collect the numbers together
228500 = c²
⇒ Square root both sides to find 'c'
478.0167361 = c
→ The length of the diagonal is 478.02
