Answer:
-3 and 5
Step-by-step explanation:
f(n) = n² - 2n - 15
numbers whose product is -15 and sums up to -2 = -5 and 3
= n²- 5n+3n - 15
= n(n - 5) +3 (n - 5)
f(n) = (n + 3)( n - 5)
n + 3 = 0 n - 5 = 0
n = -3 n = 5
Roots = -3 and 5
Let antonio's age = a and let sarah's age = s
2a + 3s = 34 (given in question)
s = 5a (given in question)
Because we know that s = 5a, we can replace it with 5a in the first equation to give this:
2a + 3(5a) = 34
∴ 2a + 15a = 34
∴ 17a = 34
∴ a = 2
Therefore we can see that Antonio is 2. Because we have been told that Sarah is 5 times Antonio's age, we can say that Sarah is 10.
