What is the given matrix?
you didn't show a matrix.
the components of the matrix are the elements.
and the elements of the inverse matrix are the elements of the inverse matrix
1) 
so if matrix A is  1   4  1   
                          2   5  2
                          3   6  3
2)
14114
25225
36336

3)
15 24 12
15 12 24
4)
[A]=(15+24+12=51)-(15+12+24=51)
[A]=0
5)
    52    23   25
    63    23   36

    41    11   14 
    63    33   36

    41    12    14
    52    12    25
6)

    15-12   6-6   12-15

     12-6    3-3    6-12

      8-5     2-2     5-8


7) 
     3    0   -3

     6    0   -6

     3    0   -3
 8) 
     (+)3    (-)0   (+)-3

     (-)6    (+)0   (-)-6

     (+)3    (-)0   (+)-3
=

    3  0  -3
   -6  0   6
    3  0  -3

9)
        3 -6  3
N=   0  0  0
       -3  6 -3
10) the inverse of [A]= 1/|A|*[N]
which is in this case ⁻A= 0
because |A|=0

on Monday Steven read 9 pages of his new book to finish the first chapter on Tuesday he needs to read double the number of pages
GarryVolchara [31]
Answer=18 pages

Steven read 9 pages on Monday. If he needs to read DOUBLE that amount on Tuesday, then we need to take the number of pages he read on Monday and times it by 2.

9*2=18pages

Steven needs to read 18 pages on Tuesday.

**Remember that Double is the same as 'two times more', or 2x more...

Given m LMN = 145°, what is m XMN?
astra-53 [7]

Answer:

m∠XMN = 80°

Step-by-step explanation:

you know that:

4x + 5 + 6x - 10 = 145

solve for x:

10x - 5 = 145

10x = 150

x = 15

Use this information to solve for m∠XMN

6(15) - 10

90 - 10

80

m∠XMN = 80°

Please help me,I need help understand so I can do my own! Worth 20 points!!
andrey2020 [161]
A)  5x⁴-8  <----- the tell-tale guy is the exponent of the variable, is 4, so the                                     degree is 4, 5x then minus then 8, two terms, a BInomial

b) 4a²-2a-16   <---- same tell-tale guy, a² has a higher exponent than say                                            "a", so, the degree is the higher exponent, degree of 2
                           it has 3 terms, thus is a TRInomial
c) 9m³  <---- well, is the only term, variable exponent is 3, so, degree of 3
                   only one term means is a MONOmial.

What is a categorical variable
Fantom [35]

It's a variable that deals with various labels, rather than the usual type of numeric variable you may be used to.

One example of a categorical variable is color. You could have red, green, blue, yellow, and orange as the five choices for your categorical variable. Each color is a label or category.

This is an example of a qualitative variable. We don't have any numeric data attached to color. They're simply names or labels. In contrast, a quantitative variable is something like a person's height since a number is attached here (more specifically its a continuous quantitative variable).
