5/6 + 3j = -2/3 I need to find the value of j

weeeeeb [17]

5/6 + 3j = -2/3

Multiply all terms by 3.

5/2 = 3j - 2

Multiply all terms by 2.

5 = 6j - 4

Add 4 to both sides.

9 = 6j

Divide both sides by 6.

j = 1.5

Rewrite this standard form quadratic equation into vertex form by completing the square. Upload your work here to show your thin

Alex787 [66]

Solution :

Given the equation :

$y = x^2 - 6x+3$

$y=1(x^2 - 6x +n)+3$

$n = \left(\frac{b}{2}\right)^2$

$n = \left(\frac{6}{2}\right)^2$

n = 9

$y=1(x^2 - 6x +9-9)+3$

$y=1(x^2 - 6x +9)-9+3$

$y=1(x-3)^2- 6$

Therefore the vertex form of $y = x^2 - 6x+3$ is $y=1(x-3)^2- 6$ .

Freida earns $5.25 per hour and time-and-a-half for overtime for all hours over 40 hours. How much did she earn the week she wor

nikdorinn [45]

Answer:

Total earned= $273

Step-by-step explanation:

Giving the following information:

Regular labor hours= $5.25

Overtime labor hours= $5.25*1.5= $7.875

To calculate the total earned, we need to use the following formula:

Regular labor hours= 40*5.25= 210

Overtime labor hours= 8*7.875= 63

Total earned= 210 + 63

Total earned= $273

What is 49.6 divided by 7.8?

fomenos

Answer: 6.4

Step-by-step explanation: If rounding to one decimal place, your answer would be 6.4.

49.6 divided by 7.8 = 6.35897435...

Now, we see that after the 3 (The first decimal place) there is a five. Because we are rounding to the first decimal place the second decimal place will tell us to round up or down. In this case because it's a five, we would round up.
