Photo math helps it worked for me so might help you :)
Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.
Part B: All we have to do is plug in 11 for x in the function given to find the answer:

In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.
Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
Answer:
Hello! answer: x = 60
Step-by-step explanation:
This is a complementary angle so it will add up to 90 degrees! here is a demonstration picture for how I solved it! Hope that helps!
Answer:
There are two bricks in the bag.
Step-by-step explanation:
1 1/3 can be written as 4/3 bricks in a bag.
(4/3)/(2/3) = 2
There are two bricks in the bag.
I think i am doing this right i am not sure. First you need to add up all the sides (100+38+22+15) it would equal 175 then you need to subtract it from 360 and get the missing value (x) then the answer would be 185
