Which ordered triple is a solution of this system? 2x + y - z = 7 -x - 2y + 4z = -15 x + 2y - 5z = 17 a) (3, 1, 0) b) (1, 3, -2) c) (2, 5, 2) d) (-2, 6, -5)

  b)  (1, 3, -2)

Step-by-step explanation:

A suitable calculator can give you the answer to this right away. Or, you can try the answer choices in the equations to see which works.

The answer choice that works is choice B.

  2·1 +3 -(-2) = 7

  -1 -2(3) +4(-2) = -15

  1 +2(3) -5(-2) = 17

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.
