What is the sum of 12 – 5i and –3 + 4i?<br> –16 + 63i <br>9 – i <br>9 – 9i <br>15 – 9i

Svetach [21]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{9 - i}}}}}$

Step-by-step explanation:

$\sf{12 - 5i + ( - 3 + 4i)}$

When there is a ( + ) in front of an expression in parentheses, there is no need to change the sign of each term. That means, the expression remains the same. Just remove the parentheses

$\longrightarrow{ \sf{12 - 5i - 3 + 4i}}$

Collect like terms

$\longrightarrow{ \sf{ 12 - 3 - 5i + 4i}}$

Subtract 3 from 12

$\longrightarrow{ \sf{9 - 5i + 4i}}$

Collect like terms

$\longrightarrow{ \sf{9 - i}}$

Hope I helped!

Best regards! :D

Investment A 50 increases each year by 8% investment B 60 increases by 3 each year what year will investment A be bigger than be

UkoKoshka [18]

Answer:

After 10 years the investment A will be bigger than investment B.

Step-by-step explanation:

In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.

If after x years the investment A will be equal to investment B, then we can write the equation as

$50(1 + \frac{8 \times x}{100}) = 60 + 3x$

⇒ 50 + 4x = 60 + 3x

⇒ x = 10

Therefore, after 10 years the investment A will be bigger than investment B. (Answer)
