Answer:

1

Step-by-step explanation:

because you cannot get two outputs from a single input in a function to put it simply

if you put 11 or any other number in a function all you can get is only one output either 5 or 8 or any number besides them.....

No! 11, the input, has two outputs which makes it not a function! :)

Answer:

a = b = 1

Step-by-step explanation:

The triangles are similar thus ratios of corresponding sides are equal, that is

\frac{10}{2} = \frac{5}{b} ( cross- multiply )

10b = 10 ( divide both sides by 10 )

b = 1

and

\frac{10}{2} = \frac{5}{a} ( cross- multiply )

10a = 10 ( divide both sides by 10 )

a = 1

Thus a = 1 and b = 1
