Answer:
y=6-3x
Step-by-step explanation:
first subtract 9x from 9x+3y=18
-9x -9x
so you get 3y=18-9x or 3y=-9x+18 then divide both sides by 3
so you get y=6-3x hope this helps :)
Answer:
10
Step-by-step explanation:
because there are 20 girls and 10 boys = 30
They are inverse functions though to be completely thorough your teacher should have also put g(f(x)) = x as well. Though I can see what your teacher is aiming for at least.
The idea is that whatever the output of g(x) is, it's plugged into f(x) and the initial input is the result. So g(x) takes a step forward and f(x) takes a step back undoing everything g(x) did. Which is exactly what an inverse operation does.
