Classify the system and identify the number of solutions. 4x + 3y + 6z = 25
x + 5y + 7z = 13
2x + 9y + z = 1

consistent, independent; one

Step-by-step explanation:

Eliminate one variable.

4(x+5y+7z=13)——- 4x+20y+ 28z= 52 (Multiply equation 2 by 4)

Subtract

Write the 2-by2 system.

17y+22z=27

-30y+8z=46

Eliminate y and solve for z

Use one of the equations in the 2-by-2 and solve for y

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
