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:
you have the same quiestion 3 times
Step-by-step explanation:
The answer would be (0,2) because as shown in the graph ab crosses the y-axis at (0,2)
Answer:
Simplify the problems first
Step-by-step explanation:
Before you can convert it to scientific notation, you should simplify it first.
#1 for example:

Use PEMDAS to solve the equation:

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be
since there are 11 places after the decimal.
Answer:
42x-24y-5
Step-by-step explanation:
We can start by using the distributive property.
This will help us rewrite the expression, since the terms in the parentheses can't be combined.
I'll attach an image to better explain this.
When using it, we'll get:
6*7x+6*-4y-5
Simplify.
42x-24y-5
This is our final answer since there are no like terms that can be combined.
