Answer:

If you're asking to simplify it will be 13x-9

Step-by-step explanation:

9(x-1)+4x

=9x-9+4x (since 9*x is 9x and 9*1 is 9)

=13x-9 - By collecting like terms (9x+4x=13x)

Semenov [28]

Thank you for the question Flo3s!

For the key worlds you are looking for is "2 1/2 miles" and "approximate"

The closest answer you would get is 13,000 feet. The actual answer is 13,200 feet. But with this we are just estimating.

1 mile = 5280' (feet)

Final Answer:

<em>13,000 feet</em>

Let f (x) = 1/x<br> and g(x) = x² – 3x. What<br> two numbers are not in the domain of fºg?
iren [92.7K]

For this case we have the following equations:

f (x) = \frac {1} {x}\\g (x) = x ^ 2-3x

We must find (f_ {o} g) (x):

By definition of composition of functions we have to:

(f_ {o} g) (x) = f (g (x))

So:

(f_ {o} g) (x) = \frac {1} {x ^ 2-3x}

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

x ^ 2-3x = 0\\x (x-3) = 0

So, the roots are:

x_ {1} = 0\\x_ {2} = 3

The domain is given by all real numbers except 0 and 3.

Answer:

x other than 0 and 3
