Answer:
B
Step-by-step explanation:
So, this is a inequality.
The inequality is 2x+2 >= 10
Lets completly ignore the graphs for the moment, and just solve this inequawlity as we would like a normal equation.
So first, subtract 2 from both sides:
2x+2>=10
=
2x>=8
Now, divide by 2 to get x alone:
2x>=8
=
x>=4
So, we now know that x is greater than or equal to 4.
In a normal inequality, we would have to remember the following:
When it is greater than/less than or equal to the dot that marks the inequalities value is filled in.
When it is greater than/less than the dot that marks the inequalities value is open, kind of like a "o".
Also, recall that the dark black line that goes either left or right of the dot also varies:
If x is less than the dot that marks the inequalities value, then the dark black line with go left.
If x is greater than the dot that marks the inequalities value, then the dark black lne will go right.
So for our x>=4, since there is a equals sign, its a filled in dot.
So four our x>=4, since there is a greater than sign, the dakr black lines goes to the right.
Now, lets look at the graphs
There is only one that has the filled in dot on 4, and a black line that goes to the right. Thats B
So B is your answer!
Hope this helps! :)
