plz help me What specific strategies did you use to determine which relation is a function? Explain why?

Use the vertical line test

Step-by-step explanation:

If a vertical line crosses through the relation on the graph only once in all of the locations, then the relation is a function. However, if a vertical line crosses through the relation more than once, then the relation is not considered a function.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
