Solution: X=9.5
Explanation: x-5.5=4 —> x=4+5.5 —> x=9.5
F(g(x)) = 2(x^2-5)-3
= 2x^2-13
g(f(x)) = (2x-3)^2 - 5
= 4x^2 + 9 -12x -5
= 4x^2 -12x + 4
If your information is for a percentage out of every 85, you need the total number divided by the 85:
391 students / out of 85
= 391 / 85
= 4.6
But in every 85, (of which there are 4.6), 10 of them are left handed (not 4.6 of them)
So multiply the 4.6 by the ten left handed students:
4.6 x 10
= 46
Therefore there are 46 left handed students in Tom's school
Answer:
inches
Step-by-step explanation:
The water level at Lake Penny changed 
inches
Again, in the next year, it is predicted to change another 
inches
Therefore, the total change that will likely occur in 2 years is (- 1.1 - 1.4 ) = - 2.5 inches = inches. (Answer)
