The value of 
is 
Explanation:
Given that 
and 
<u>The value of </u><u>:</u>
The value of can be determined by substituting x = 5 in the functions f(x) and g(x) and then dividing the terms, we get, the value of
Thus, we have,
Substituting the value of x = 5 in the functions f(x) and g(x), we get,
Simplifying the terms, we have,
Adding the terms in numerator, we have,
Thus, the value of is
The statement " <span>y </span><span>varies directly as </span><span>x </span><span>," means that then </span><span>x </span>increases,<span>y </span><span>increases </span><span>by the same factor so we have: y/x=k
for question 1 then: 15/5=3
so the direct variation equation is y=3x
Now if x=9 you only have to replace x in your equation and you get:
y=3*9=27</span>
Answer:
33
Step-by-step explanation:
It's decreasing by 7
17y -24y +13y -y = 210
(17-24+13-1)y = 210
5y=210
y=42
