<span>f(x) and g(x) are </span>2(x + 2) and 4x² respectively so
that the function can be expressed as y = f(g(x)). I am hoping that these answers
have satisfied your query and it will be able to help you in your endeavors,
and if you would like, feel free to ask another question.
Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12
Umm all you would have to do is cross multiply.
4x/5 would be multiplied by 5/4 and you would get you x freed.
Hope that helped!

N + 150 = 227 <=== ur equation.......n = unread pages
n = 227 - 150
n = 77...so she has 77 more pages to read to complete the book
10:40
This ratio is 10/40. Divide both by 10. You will get 1/4. 1/4 is 1:4.
So, we have one answer
1/4
5:20
This ratio 5/20. Divide both by 5. You'll get 1/4. 1/4 is 1:4
1:4
1:4 is the ratio we had before.
3:12
This ratio is 3/12. Divide both by 3. You'll get 1/4. 1/4 is 1:4
1:4
8:33
This ratio can not be reduced further.
So, the solution is 8:33 which has a different ratio from all the other ones
