Answer:
A)
B)
Step-by-step explanation:
On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression .
On the right, we have six -1s. So, we can represent the right with the expression .
A)
Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:
B)
Now, we can solve the equation for x. Add 1 to both sides:
The left will cancel. Add on the right:
Finally, divide both sides by 5:
The left side will cancel. So, the value of x is:
Answer:
open left
Step-by-step explanation:
We can distribute the left side to get .
We can then add to both sides of the equation to get .
We can finally divide both sides of the equation to get .
Because it's a and not a , it is closed. And because the inequality opens to the right, it faces to the left.
So, it is a open left graph.
