Answer:

How you can tell

Step-by-step explanation:

A function assigns exactly one output to each input: x/input y/output

How they work: X <u>can not repeat</u> but Y <u>can</u>.

Lets see your problem, there are no inputs repeating and the outputs are fine.

That is a function!

(5ab-9a-4) - (-4ab + 5)
qaws [65]

Answer:

9ab - 9a +1

Step-by-step explanation:

first, we can distribute the negative sign to the second set of parentheses.

-(-4ab + 5) becomes + 4ab - 5

now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5

5ab + 4ab - 9a - 4 - 5

= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.

Anon25 [30]
1/4 = 0.25
