Answer:
Step-by-step explanation:
Arrange the equations so that all the variables are in columns (x as the first column, y as the second, equals a number as the third):
-11x - 4y = 36
5x + 5y = -10
Define and edit Matrix A. We need a 3 x 2 matrix. Input the coefficients and constant:
![\left[\begin{array}{ccc}-11&-4&36\\5&5&-10\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-11%26-4%2636%5C%5C5%265%26-10%5Cend%7Barray%7D%5Cright%5D)
Find rref function, enter matrix A: rref([A]) (press enter)
This gives you:
![\left[\begin{array}{ccc}1&0&-\frac{44}{7}\\0&1&\frac{58}{7}\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-%5Cfrac%7B44%7D%7B7%7D%5C%5C0%261%26%5Cfrac%7B58%7D%7B7%7D%5Cend%7Barray%7D%5Cright%5D)
which means:
First you have to turn pounds into ounces and its 16 oz for 1 pound.
Now you need to multiply 16 by 5.
16×5=80
Now you add the 4 oz to the 80 oz.
80+4=84
Now you need to divide $26.88 by the 84 oz.
26.88÷84=0.32
Then you finally get $0.32 per 1 oz.
I really hope that helped : )
Answer:
$75
Step-by-step explanation:
<h3>Steps to determining the answer</h3>
- Determine the number of students that would pay in the second week. This can be known by subtracting 14 from 20. 20 is the total number of students. 14 is the number of students that paid in the first week.
- Multiply the answer gotten from one above by the price of the ticket
20 - 14 = 6
6 students would pay in the second week
6 x $12.50 = $75
The teacher would collect $75 in the second week
The ordered pairs would be (x-2, -y).
Translating a graph to the right subtracts the number of units from the x-coordinate.
Reflecting across the x-axis negates the y-coordinate.
