Remember, the graph of a line represents every point that is a possible solution for the equation of that line. So when the graphs of two equations cross, the point of intersection lies on both lines, meaning that it is a possible solution for both equations. When the graphs of two equations never touch, there are no shared points and there are no possible solutions for the system. When the graphs of two equations lie on top of one another, they share all their points and every one is a possible solution.

Answer:
he have left 4.45 kg
Step-by-step explanation:
The computation of he have left is as follows:
= Total salt purchase - salt used on his sidewalk - sales used on the driveway
= 4.45 kg
Hence, he have left 4.45 kg
For this case we have the following expression:
-x (7x + 2) + x ^ 2
Rewriting we have:
(-7x ^ 2 -2x) + x ^ 2
Adding similar terms we have:
-6x ^ 2 - 2x
Answer:
The simplified expression is given by:
-6x ^ 2 - 2x
I think it’s step 2 or 3 I’m not sur
The slope is the first choice you chose
