Simplify the expression.
-5+i /2i

The simplification of the expression -5+i /2i is; (5i +1)/2

From the concept of complex numbers;

We know; i = √-1 and i² = -1

To simplify the expression -5+i /2i;

We must first multiply the numerator and denominator by i; so that we have;

= (-5i + i²)/2i²

where, i² = -1

= (-5i - 1)/-2

= -(5i + 1)/-2

= (5i +1)/2

Step-by-step explanation:

We know i×i=i^2 which has value of -1.

We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).

Also multiplying by i/i does not change the value of the fraction because i/i=1.

Numerator × i gives (-5+i)i=-5i+i^2=-5i-1

=-1-5i.

Denominator × i gives (2i)i=2i^2=-2.

So the simplified version of this fraction given is:

The last simplification come from me multiplying fraction by -1/-1.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

the answer is simply just 6n add the two together as they have an n
