4 0
Answer: 1 solution

An augmented matrix for the system is
[2,6,12;1,1,2] where we will call the first two columns A and the third b. A is linearly independent since it is row equivalent to the identity matrix, which tells us that for any b there will be a unique solution (x,y).

The price of Stock A at 9 A.M. was ​$14.83. Since​ then, the price has been increasing at the rate of ​$0.12 each hour. At noon
BARSIC [14]

Answer:

  • 0.5 hours

Step-by-step explanation:

Let the x be the number of hours after noon.

<u>We have the following equation:</u>

  • 14.83 + 0.12(x + 3) = 15.33 - 0.15x
  • 14.83 + 0.12x + 0.36 = 15.33 - 0.15x
  • 0.12x + 0.15x = 15.33 - 15.19
  • 0.27x = 0.14
  • x = 0.14/0.27
  • x ≈ 0.5
