Which system of equations represents the matrix shown below?
11 2 21 15
2 3 6 -29
13 9 2 | 22
11x +2y +212 - 15
A. 2x+3y +62--29
13x+9y+2z - 22
11x +2y - 212-15
B. 2xy +62--29
13x+9y+z=-22
11x +2y +212 = 15
C. 2x - y +z = -29
13x+9y + 4z =-22
11x + 2y - 212-15
D. 2x - 3y +z = -29
13x +9y+2z--22

step-by-step explanation:

i hate black

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
