What is a matrix?
A matrix, which is used to represent a mathematical object or an attribute of one, is a rectangular array or table containing numbers, symbols, or expressions that are organized in rows and columns.
The given matrix is,
[tex]\left[\begin{array}{cc}6&-4\\-9&6\\\end{array}\right][/tex]
The determinant of the matrix will be calculated as below:-
D = ( 6 x 6 ) - ( -9 x -4 )
D = ( 36 - 36 )
D = 0
Here the determinant of the matrix is zero. Therefore, the matrix is not invertible.

A jewelry store is having a going out of busniess sale. All merchandise is marked 40% off the reguler price. The regualr price of a watch is $59.95. Find the amount of the discount and the sale price.
Answers
Answer:
Amount of the Discount: $23.98
Sale Price: $35.97
Step-by-step explanation:
In order to calculate the discount we first need to turn this percentage into a decimal by dividing it by 100. Once we have it in decimal form we subtract that value from 1. Finally, we multiply this new decimal by the original price in order to obtain the sale price like so...
40 / 100 = 0.40
1 - 0.40 = 0.60
0.60 * 59.95 = 35.97
Now we have the sale price which is $35.97 now we can subtract this value from the original price to calculate the amount of the discount.
59.95 - 35.97 = 23.98

AB and BC form a right angle at point B. If A= (-3,-1) and B = (4,4), what is the equation of BC?
A. x+3y= 16
B. 2x+y= 12
C. -7x - 5y=-48
D. 7x-5y= 48
Answers
Answer: We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48
Answer:

Find the measure of an interior angle of a regular dodecagon(12-sided polygon). Hint: Sum = (n-2)180
Answers
Step-by-step explanation:
Sum of interior angles in a polygon = 180°(n - 2).
Size of interior angle in a regular polygon
= 180° - 360°/n
= 180° - 360°/12
= 180° - 30°
= 150°.

In the diagram. PQ is parallel to BC.
APB and AQC are straight lines.
PQ = 8 cm, BC = 10 cm and AB = 9 cm.
Calculate PB
Answers
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]
Plug in the values
[tex] \frac{9}{AP} = \frac{10}{8} [/tex]
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
