Which classification best describes the following system of equations?

x-y-z=0
2x-y 2z=1
x-y z=-2

a: inconsistent and dependent
b: consistent and dependent
c: consistent and independent
d: inconsistent and independent

The correct option is c.

Step-by-step explanation:

The given equations are

                 .... (1)

            ..... (2)

              .... (3)

Subtract equation (3) form equation (1).

The value of z is -1. Put this value in equation (1) and (2).

               .... (4)

           ..... (5)

Subtract equation (5) from equation (4).

The solution of given system of equations is (4,5,-1). It is a unique solution.

Therefore the given system of equations is consistent and independent. Option c is correct.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
