Let Sarah's age be s and Antonio's age be a.
According to your question,
2a + 3s = 34
s = 5a
substituting the value of s in eq. 1,
2a + 3(5a) = 34
= 2a + 15 a = 34
17a = 34
thus, a = 34/17 = 2
substituting the value of a is s,
s = 5(2)
= 10
Thus, Sarah's age is 10 years and Antonio's age is 2 years.
Answer:


Step-by-step explanation:
We are given that

y(0)=-1


Taking integration on both sides then we get


Using formula


Substitute x=0 and y=-1



Substitute the value of C



By using quadratic formula


Hence, the solution 
When the solution is maximum then y'=0
