Answer:
V looking graph
(absolute value function)
Step-by-step explanation:
We are looking for a relation that passes the vertical line test.
Basically if you can play a vertical line on your graph and it touches more than once on that vertical line (your graph) then it isn't a function.
The only one that is a function here is the V looking graph.
The questions 1, 2, and 5 are already matched in correct order.
<u>Step-by-step explanation:</u>
1. <u>Meter</u> - standard metric unit of length.
2. <u>hypothesis</u> - a proposed explanation for a scientific problem.
3. <u>mass</u> - amount of matter in an object.
4. <u>liter</u> - standard unit of volume.
5. <u>control</u> - a quantity in an experiment that remains unchanged or constant.
6. <u>meniscus</u> - the curved top surface of a liquid column.
When you add and subtract be sure that the two fractions have the same denomination, and then add/subtract the numerators. I always do cross multiplication of the two fractions to obtain the same denominators-although there are various ways to do this.
Multiplying fractions is simply straight across.
Dividing fractions:
Keep, change, flip.
Keep the first fraction the same, change the sign to its opposite (ex:division flips to multiplication), and flip the numerator and the denominator of the second fraction. Then, preform the arithmetic from your "new" problem.
