What is the value of 6i/1+i? 2 – 6i 2 + 6i 3 – 3i 3 + 3i
mihalych1998 [28]

6i/ (1+i)  

multiply by the complex conjugate (1-i)/(1-i)

6i/(1+i) *  (1-i)/(1-i)

6i* (1-i) = 6i - 6i^2 = 6i - 6(-1) = 6i +6

(1+i)*(1-i)= 1-i +i -i^2 = 1 -i+i -(-1) = 1+1=2

(6+6i)/2

3+3i

Answer: 3+3i

Vijay has an annual salary of 47,000, and his company pays him twice a month. What is the gross income in each paycheck that Vij
leonid [27]
Alright, so he has an <em>annual </em>salary of 47,000 dollars. Which means that he is paid 47,000 dollars in 12 months. You'll first have to calculate the pay Vijay receives <em>each month</em>, which is \frac{47,000}{12 months}, or about $3,916.67 (I'll round up to 3917 for simplicity). 

Now, he gets paid twice a month. So each paycheck is half of $3917. 3917 x (1/2) = $1958.50. 

So each paycheck should be $1958.50 (this is a rounded figure).

Justin is working two summer jobs, making $8 per hour babysitting and $14 per hour lifeguarding. Last week Justin earned a total
alexdok [17]

Answer:

Justin worked as a babysitter  8 hours and worked as a lifeguard 2 hours last week

Step-by-step explanation:

Let

x ----> number of hours worked as a babysitter  last week

y ----> number of hours worked as a lifeguard last week

we know that

8x+14y=92 ----> equation A

x=4y ----> equation B

Solve the system by substitution

Substitute equation B in equation A

8(4y)+14y=92

solve for y

32y+14y=92

46y=92

y=2

Find the value of x

x=4(2)=8

therefore

Justin worked as a babysitter  8 hours and worked as a lifeguard 2 hours last week

Two car-rental agencies are competing for business. Mertz charges $35 a day and $0.15 per mile, and Mavis charges $20 a day and
Nata [24]
Well we overall have two different equations we can make here with two different variables. If 35 & 20 were to be our daily charge, and y is our per mile charge, we can infer that x times y is equal to our overall car-rental price, so if we set it out correctly, our equations should be
35 x (y).15 =
20 x (y).45 =
