## anonymous one year ago Given the functions m(x) = 4x − 11 and n(x) = x − 10, solve m[n(x)] and select the correct answer below.

m[n(x)] = 4x − 51 m[n(x)] = 4x − 29 m[n(x)] = 4x2− 51 m[n(x)] = 4x2 − 29

OK. Slightly trickier, but the method is exactly the same.

4. anonymous

If we want m(n(x)), then you must take n(x) first. That is given as $n(x) = x - 10$Now, to find $$m(n(x))$$, you must calculate $$m(x-10)$$. Using the function m(x), substitute $$x-10$$ for $$x$$.

In other words$m \left( n \left( x \right) \right) = m \left( x-10 \right) = 4\left( x-10 \right)-11$What do you get?

6. anonymous

ummm what are putting for x

7. anonymous

Nothing, just leave it as x. Notice there are x's in all the answers.

irdk im sry

No problem. So you need to figure out 4(x-10) - 11. Take it one bit at a time. Can you multiply 4(x-10)?

10. anonymous

4x-40

11. anonymous

distribute

12. anonymous

Perfect. Now subtract 11 from that answer, i.e. 4x - 40 - 11.

13. anonymous

Combine the -40 and the -11.

14. anonymous

sry it is --51 @ospreytriple

15. anonymous

Right. So your answer is 4x - 51. OK?

16. anonymous

yes sry i was doing something with my teacher over the phone @ospreytriple
