Hey there 
9+10 = 19 

It is impossible for it to be 21 
21 can only be when you add 10+11

The answer is No. 9+10 can not be 21

hope this helps

On the function machine shown below, the function rule is given as a variable expression. When the output is 99, what is the inp
beks73 [17]

Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2  - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1  =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.
