Answer:
Step-by-step explanation:you take the biggest number on the graph and then you subtract the smallest number from it so if the biggest was 5, and the smallest was 3, you would do 5-3=2 and then 2 is your range
True
I have notes on this so im pretty sure
The percentage of the golf clubs original price to its new inflated price is: %1.15 more expensive. To find out the percentage, we just need to divide 552 by 480: 552/480 is 1.15. That is our percentage.
angleBOC = 270°
All 3 angles meet at O thus
angleBOC = angle AOC + angle BOD = 120° + 150° = 270°
For this case we have the following system of equations:
We can Rewrite the system of equations of the form:
Where,
A: coefficient matrix
x: incognita vector
b: vector solution
We have then:
![A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]](https://tex.z-dn.net/?f=%20A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%263%5C%5C-8%26-3%5Cend%7Barray%7D%5Cright%5D%20%20)
![x=\left[\begin{array}{ccc}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%20x%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%20)
![b=\left[\begin{array}{ccc}17\\9\end{array}\right]](https://tex.z-dn.net/?f=%20b%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D17%5C%5C9%5Cend%7Barray%7D%5Cright%5D%20%20)
Then, the determinant of matrix A is given by:
Answer:
The determinants for solving this linear system are:
