What is the solution of the matrix equation?

katrin [286]

Hello from MrBillDoesMath!

Answer:

The first choice ( -12, 20)

Discussion:

Using matrix multiplication we find the equations:

1x + 1y = 8 (A)

2x + 3y = 36 (B)

Next, compute

2(A) - B =>

(2x + 2y) - (2x + 3y) = 2*8 - 36 =>

(2x - 2x) + ( 2y-3y) = 16 - 36 =>

-y = -20 =>

y = 20

Substituting this y value in (A) gives

x + 20 = 8 =>

x = 8 - 20 =>

x = -12

The answer is the first choice ( -12, 20)

Thank you,

Answer:

We have to put the data for purchased item in a frequency table.

Step-by-step explanation:

The diagram is attached below.

Firstly we have to see that how many customers fall under range $0 to 5$ .

Then $5 to 10$ .

Then $10 to 15$ .

Finally

$15 to 20$ .

If we go through the items purchased by customers we can see that item ranges from $0 to 5$ have $4$ customers.

Item purchased range from $5 to 10$ have $2$ customers.

Item purchased range from $10 to 15$ have $7$ customers.

Item purchased range from $15 to 20$ have $1$ customers.

Total number of customers = $14$

As we have total $14$ number of customers and they have varied quantity of items purchased.
