Answer:
390
Step-by-step explanation:
500*.22=110
500-110=390
390
7x - 8(-2 + 9) = 112
7x - 8(7) = 112
7x - 56 = 112
7x = 112 + 56
7x = 168
x 168/7
x = 24 <==
So it is given that f(x) and g(x) are inverse of each other.
Then f(5) = -7 and hence g(-7) = 5
Now let's use f( g( x ) ) = x
Now take deviation. Use chain rule:
f'( g(x) ) g'( x ) = 1
Plug in x = -7
f'( g( -7 ) ) g'( -7 ) = 1
f'( g( -7 ) ) · -2/3 = 1
f'( g( -7 ) ) = -3/2
f'( 5 ) = -3/2
Hope this helps.
1427 = (F) (+ F + 60) (2F - 50) (+ 3F)
<em>Each pair of brackets represents one of the classes - F meaning Freshmen Class. It has been split into brackets for demonstrational purposes - nothing is being multiplied.</em>
F is an unknown number and each other class size is based off of that so we put it in algebraic terms in order to work it out.
1 - Freshmen Class
2 - Sophomore Class (Freshmen Class + 60 more students)
3 - Junior Class ( Twice the size of the Freshmen Class - 50 students)
4 - Senior Class (Three times the size of the Freshmen Class)
All this can be simplified to 7F + 10 = 1427
1427 - 10 = 1417
1417/7 = 202.428....
Is there a mistake in the question?
Following the question with 202 as the answer - the number 1424 is reached
If increased to 203 - 1431 is reached.
The answer shouldn't include half a person.
