A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use

or

to represent that situation, whereas a white dot indicates that the number is not contained within the inequality.
Our graph is telling us that

is greater or equal than -1, and also

is less than 3. So our inequality will be:
Answer:
The answer is y = 20
Step-by-step explanation:
To find this, we need to turn it into an equation. Then we can follow the order of operations to solve.
y - 12 = 8
y = 20
All real numbers
7w-(2+w) = 2(3w-1)
Expand
7w-(2+w)= 6w-2
7w-2-w=6w-2
Group like terms
6w-2=6w-2
Add 2 to both sides
6w=6w
subtract 6w from both sides
0=0
True for all w

Answer:
8
Step-by-step explanation:
Your familiarity with multiplication tables tells you ...
