Answer:

Properties used here are:

A Associative property

B Commutative property.

Step-by-step explanation:

Given the expression:  (4+3i)+(8+2i)

(4+3i) + 8 + 2i

Using associative property: a+(b+c) = (a+b)+c

4+(3i+ 8) + 2i

Using commutative property:  a+b=b+a

4+(8+ 3i) + 2i

(4+8)+ 3i+ 2i             [Using associative property]

(4+8)+ (3i+ 2i)

Simplify:

12+ 5i

Is point (2,1) on the the line represented by the equation x+2y=5
Sphinxa [80]
To check if this point lies on the line, plug in a 2 for x and a y for 1 and solve

x+2y=5
2+2(1)=5
4=5

Since this statement isn't true, then the point doesn't lie on the line

Hope this helps

What would happen to a monthly payment if the interest rate increased?
Shalnov [3]

In most cases, if the interest rate increases, the payment will also go up or increase.

<h3>What is the interest rate?</h3>

When you have a loan or debt, the interest rate refers to the amount of money per month, year, etc. that you paid for the benefit of having borrowed the money.

  • This is usually a small percentage of the total debt.

<h3>What happens if the interest rate increases?</h3>

This increases your total debt, and therefore, you will need to pay more money every month or year.
