Divide 3x^2-x-2 by x+4

2 answers:

7 0

The answer would be 3x^2-13+50/x+4

Explanation:
You can use synthetic division to solve this.
How you do synthetic division you have to take the number on x+4 and change its sign

Which is -4

Then you take A B and C (in this case A B and C is 3, -1, and -2)

To do synthetic division you bring the 3 down and multiply it by -4 and add the answer to the -1

Then you have 3-13 which you can change into 3x-13. For this specific problem it has a remainder.

You find the remainder by going back to your -4 and multiply it by the -13 (which is 52 because a negative times a negative equals a positive) and add the 52 to -2 which is 50.

So your final answer is 3x-13+50/x+4

I’m sorry if this was confusing written out like this. If you want to learn how to do synthetic division search it up.

Hope this helps

8 Line in the xy-plane contains points from each of Quadrants II, III, and IV, but no points from Quadrant I. Which of the follo

iren2701 [21]

Answer:

The correct option is D.

Step-by-step explanation:

The slope of a line is the change in y with respect to x.

$m=\frac{y_2-y_1}{x_2-x_1}$

If the slope of a line is undefined it means it is a vertical line and a vertical line can not passes through three quadrants. So, option A is incorrect.

If the slope of a line is 0 it means it is a horizontal line and a horizontal line can not passes through three quadrants. So, option B is incorrect.

If the slope of a line is positive it means the value of y increases as x increases.

Since it is an increasing line, therefore after a certain period both x and y will positive. It means the line will passes through first quadrant. So, option C is incorrect.

If the slope of a line is negative it means the value of y decreases as x increases. It can passes through each of Quadrants II, III, and IV.

Therefore the correct option is D.

Algebra help needed!!

The population triples ( P × 3 ) every ten minutes...

So if ten minutes is reached there will be 1,200 bacteria.

Edited - missed the question
** The units for time should be in minutes.

P = 400 × 3^(t/10)

at t = 0 ; P = 400
at t = 10 ; P = 1,200

When P = 600
600 = 400 × 3^(t/10)
6/4 = 3^(t/10)
Log(3/2) = Log(3^(t/10))
power rule
Log(3/2) = (t/10) Log(3)
10 × Log(3/2)/Log(3) = t

3.69 minutes the population will be at 600 bacteria
Unites for time are in minutes.

20 POINTS ! An international company has 17,800 employees in one country. If this represents 22.1% of the company's employees, h

n200080 [17]

Answer:

80,543 employees total

Step-by-step explanation:

22.1% of total = 17,800 employees

0.221 of x = 17800

0.221 • x = 17800

x = 17800 / 0.221

x = 80542.98643

x ≈ 80543 employees total

Helppppppp plz god bless u 10 points

wariber [46]

I believe D). 5 is the answer. If you clearly think about it, it actually might make sense. You just count the lines pointing from up to down.
