Is if you round the 7 to a 10 and do the 12 round it to a 10 10 Times10 is 100

Answer: Choice C</h3>
Why isn't choice C a function? It's because we have the input x = 4 lead to more than one output at the same time (y = 5 and y = -5). A function must have all allowed inputs lead to exactly one output.
The diagram for choice C shows we have the points (4,5) and (4,-5). If we plotted those two points, then a vertical line forms, which will show this relation fails the vertical line test.
Choices A, B, and D do not have this happen where a certain input leads to multiple outputs at once; therefore, these are all functions. For the tables A and D, note there aren't any repeated x values. If you were to convert choice C into table form, then you would have the x value 4 repeat itself.
Answer:
Step-by-step explanation:
Question: 
1) Subtract 79 from both sides:
2) Add 59p to both sides:
3) Divide both sides by 28:
4) Simplify fraction:
Answer:
To solve for x the equation would be. (120 - 48) ÷ 2 = X
Step-by-step explanation:
This is because to follow pemdas you do the parenthesis first so you subtract both of the shorter sides. Next since there are two longer sides you divide by two to get the answer. Each longer side is equal to 36 inches.
Hope this helps
