A rodar pulse is sent from the Earth to an asteroid, bounces off and returns to Earth. The radar pulse travels of the speed of light (300,000 km/sec) and takes 150 seconds to
travel out and return. How far away is the asteroid?

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
