The value of the matrix X is
<h3>How to solve for matrix X?</h3>
The attached image represents the complete question
The given matrices are:
The expression is given as:
A(X - B) = C
Expand
AX - BX = C
This gives
Evaluate the products
Evaluate the difference
By comparing the positions, we have:
6a - 4c = -1
6b - 4d = 2
4a - 4c = -2
4b - 4d = 2
Rewrite as:
6a - 4c = -1 and 4a - 4c = -2
6b - 4d = 2 and 4b - 4d = 2
Using a graphing tool, we have:
a = 0.5, c = 1, b = 0, and d = -0.5
Hence, the matrix X is:

Answer:
The domain of this function is first restricted to all non negative integers because the theater can sell only a whole number of tickets.
The domain is restricted to numbers less than or equal to 125 because the theater cannot sell more tickets than capacity.
Step-by-step explanation:
<u>Given</u><u> </u><u>Information</u><u> </u><u>:</u><u>-</u>
⠀
- Each exterior angle of a regular polygon has a measure of 40°
⠀
<u>To</u><u> </u><u>Find</u><u> </u><u>:</u><u>-</u>
⠀
- The number of sides of the polygon
⠀
<u>Formula</u><u> </u><u>Used</u><u> </u><u>:</u><u>-</u>
⠀
⠀
<u>Solution</u><u> </u><u>:</u><u>-</u>
⠀
Using the formula,
⠀
⠀
Thus, the polygon is a nonagon, and hence has 9 sides.
⠀
K^2-16
=(K-4)(k+4)
Because 4 • -4= -16
