A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.
This is in my opinion. Im not sure if it is correct or not but Good luck!
Answer:
C. y<3
Step-by-step explanation:
We are required to determine the solution set of the inequality

Step 1: Add 9 to both sides

Step 2: Divide both sides by 15

The solution set of the given inequality is: y<3.
The correct option is C.
Answer:
60 time 10

Answer:
12 units
Step-by-step explanation:
base is x
one of the legs measure 4x-6
therefore, perimeter is equal to
2 (4x - 6) + x = 96
8x - 12 + x = 96
9x = 96 + 12
9x = 108
x = 108/9 = 12 units
