Answer:

$x=20$

Step-by-step explanation:

Since angle RTS is a right angle, we have three similar triangles.

Thus, $\frac{x}{25} = \frac{16}{x}$

Cross Products, $x^2=400$

Take the square root: $x=20$

Determine whether each pair of functions are inverse functions. 1) f(x) = 8x – 10, g(x) = (x + 10) 2) f(x) = 4x + 5, g(x) = 4x –

Answer:

Step-by-step explanation:

To find the inverse of a function you take it in y=f(x) form, switch x and y and then solve for the new y.

So I'll do the first one.

f(x) = 8x-10

y=8x-10 Now switch x and y

x = 8y-10 Now solve for y.

x+10=8y

(x+10)/8 = y

g(x) is not that, so it is not the inverse. Can you figure out the second one?
