Which Matrix Equation Represents The System Of Linear Equations?3x-9y-Z=-4-2x + Y - 8z = 15x + 2y + 2z

Answers

Answer 1

9514 1404 393

Answer:

  B

Step-by-step explanation:

When solving multiple choice problems, a reasonable strategy is to look for ways to identify one answer as good, or other answers as bad.

Here, all of the constant vectors in the equations are different, so we can decide the answer based on that.

The only equation with the correct constant vector is choice B.

_____

The constants in the equations are -4, 1, 9 — the values to the right of the equal sign.

Using the variable n for the term, describe the sequence.

Answers

Answer:

3 + 5n

Step-by-step explanation:

This is an arithmetic sequence.

First term = a = 8

Common difference = d =Second term - first term

                                = 13 - 8

                                 = 5

Nth term = a + (n- 1)*d

              = 8 + (n -1) * 5

             = 8 + n*5 - 1 *5

              = 8 + 5n - 5

               = 8 - 5 + 5n

Multiplying by which number is equivalent to an increase 49.5%

Answers

Answer:

22.46

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

49.5% = 49.5/100 = 49.5 ÷ 100 = 0.495.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 49.5% of its value.

Percentage increase = 49.5% × 22.46

New value = 22.46 + Percentage increase

22.46 equivalent an increase 49.5%

Monica deposits $300 into a savings account that pays a simple interest rate of 4.2% paul deposits $400 into a savings account that pays a simple interest rate of 3.8% monica says that she will earn more interest in 1 year because her interest rate is higher is she correct?

Answers

Answer:

Paul earned $2.6 more interest than Monica.

Step-by-step explanation:

Giving the following information:

Monica:

Initial investment= $300

Interest rate= 4.2%

Paul:

Initial investment= $400

Interest rate= 3.8%

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

I= P*r*t

P= principal

r= interest rate

t= time

Monica:

I= 300*0.042*1= $12.6

Paul:

I= 400*0.038*1= $15.2

Paul earned $2.6 more interest than Monica.

Let’s convert Angelicas height in inches so all the measurements are the same.

Anglelicas height: 4 ft7 in

OR

Angelicas height: 55 inches

Dolls height: 11 inches

The ratio would be 55:11 but we would need to simplify since both numbers are divisible by a GCD (greatest common denominator)
