Trong không gian R2, cho tích vô hướng (x, y)=((x1;x2),(y1;y2))=x1y1−x1y2−x2y1 +3x2y2. Tính độ dài của véctơ v=(−1;3)

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

answer: ok

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
