Answer:
multiply the left side of the constant vector by the inverse matrix
Step-by-step explanation:
The matrix equation ...
AX = B
is solved by left-multiplying by the inverse of A:
A⁻¹AX = A⁻¹B
IX = A⁻¹B . . . . . the result of multiplying A⁻¹A is the identity matrix
X = A⁻¹B . . . . . B needs to be multiplied by the inverse matrix

g(x) = x² - 5x + 2
You are looking for g(0). This means that you must replace all the x values in the equation above with 0
(0)² - 5(0) + 2
Now you need to solve according to the rules of PEMDAS:
(0)² - 5(0) + 2
0 - 5(0) + 2
0 - 0 + 2
0 + 2
2
g(0) = 2

2,2,2,2,3,5,7,9,9,10,11,12,18 find the median
Natasha2012 [34]
Answer:
median = 7
Step-by-step explanation:
The median is the middle value of the data set arranged in ascending order
2, 2, 2, 2, 3, 5, 7, 9, 9, 10, 11, 12, 18
↑ middle value
median = 7
<u>PERIMETER</u>
Answer:
Answer is 28 m
Step-by-step explanation:
Breadth= 2m
Length= 2X6m
= 12m
Perimeter of a rectangle = 2X (Length+ Breadth)
= 2X (2+12)
= 2X14
= 28m
<u>AREA</u>
Answer:
Answer is 24 m
Explanation:
Length= 12
Breadth= 2
Area of a rectangle= Length X Breadth
= 12X2
= 24 sq. m
Hope it helps ;)
