You can use the distibutive property by breaking apart the bigger number (38) into 30 and 8. Now, you can do: (9 x 30) + (9 x 8)
I hope this helps!!!

Given that f(x) = 2x + 5 and g(x) = x − 7, solve for f(g(x)) when x = −3
dusya [7]

Answer:

-15

Step-by-step explanation:

start from the inside and go out.

So first plug in -3 into g(x)

g(-3) = -3 - 7 = -10

then plug in -10 into f(x)

f(-10) = 2(-10) + 5 = -15

so f(g(x)) = -15

F(x)=√x+11. Find the inverse of f(x).
MaRussiya [10]

Answer:

f(x)⁻¹ = (x - 11)²

Step-by-step explanation:

To find the inverse of the function, you need to (1) swap the places of the "x" and "y" variables and then (2) solve for "y". Remember, f(x) is another way of writing "y".

y = √x + 11                                        <----- Original equation

x = √y + 11                                        <----- Swap variables

x - 11 = √y                                         <----- Subtract 11 from both sides

(x - 11)² = (√y)²                                  <----- Square both sides

(x - 11)² = y                                        <----- Simplify

Another way of writing the output of an inverse function is with f(x)⁻¹.

On a 16 scale drawing of a bike, one part is 3 inches long. How long will the actual bike part be?
Arisa [49]
You would multiply 16*3 to get an estimate. 
16*3= 48
The bike would be about 48 units.
I'm assuming you mean a 16:1 scale.
16:1= 16/1 which =16 
Hope this helps!
