Answer:

1. 6

2. 23

Step-by-step explanation:

1.

logx+1 ( x^2 + 2x + 1)^3

= 3logx+1  ( x^2 + 2x + 1)

= 3 logx+1 (x + 1)^2

= 6 logx+1 (x + 1)  Now the logx+1 x+1 = 1  so

The answer is 6.

2.

log11 11^23

= 23 log11  11

As in question 1 log11 11 = 1

So the answer is 23.

Matt invested $1500 into a stock of his choice. After two years, he had received
EleoNora [17]

For this question, the time given confuses me.  I know the rate of return is just total return divided by divided by investment, Assuming that Matt received the $400 in dividends as cash payouts, and they weren't reinvested into buying shares of the stock, then his total return over two years was $500, Now, if Matt's dividends were reinvested into the stock - and if you have a 401(k) or IRA, that's what usually happens - then his ROI would have been only 6% because he only made a profit of $100 on an investment of $1500. Note:  In the real world, in current market conditions, Matt probably would have got about a 5% return on a good stock, and Bella would have received about 0.05% on a savings account.

hope this helped you ;)

2. Which of the following ordered pairs (x,y) satisfies the system of equations below?
nataly862011 [7]

Answer:

x=2, y=-2

(2, -2)

Step-by-step explanation:

x + y = 0

3x - 2y = 10

3x - 2(0 - x) = 10                  ( 2(0 - x) = -2x )

3x - (-2x) = 10                      ( y = -x )

3x + 2x = 10

5x = 10

x = 2

Hope i helped, feel free to ask questions :D

Have a good day!
