{(1, 7.6) (2, 7.2) (3, 6.8) (4, 6.4) (5, 6) (6, 5.6)}

Is this a function or no?

Yes

Step-by-step explanation:

Let's put them vertically because that helps me explain this

x, y

1, 7.6

2, 7.2

3, 6.8

4, 6.4

5, 6

6, 5.6

For this to be a function there should be one output for every input, the y coordinates are our outputs and as you can see none of them repeat so this is a function.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
