The correct answer would be 5/2.
As this is the mixed fraction equivalent.
Hope this helps! c:
You can do this in parts.
g(-3) = 3(-3) + 1 = -9 + 1 = -8
So, 5g(-3) = 5(-8) = -40.
So f(-1) + 5g(-3) = 2 - 40 = -38
Or you can do this as one big chunk.
f(-1) + 5g(-3)
![=[(-1)^2+1] + 5[3(-3) + 1] \\ = (2) + 5(-9 + 1) \\ = 2 + 5(-8) \\ = 2 - 40 \\ = -38](https://tex.z-dn.net/?f=%3D%5B%28-1%29%5E2%2B1%5D%20%2B%205%5B3%28-3%29%20%2B%201%5D%20%5C%5C%0A%3D%20%282%29%20%2B%205%28-9%20%2B%201%29%20%5C%5C%0A%3D%202%20%2B%205%28-8%29%20%5C%5C%0A%3D%202%20-%2040%20%5C%5C%20%3D%20-38)
Answer:The present age of both of them are Christopher = 42 years, and Ishaan = 84 years.
Step-by-step explanation: Solution:
Let present age of:
Christopher =
x
yrs
Ishaan =
2
x
yrs ( given that Ishaan is 2 times as old as Christopher)
35 yrs ago:
Age of Christopher = (
x
- 35)yrs
Age of Ishaan = (
2
x
- 35) yrs
According to question, 35 yrs back, Ishaan was 7 times older than Christopher.
Therefore
7 X (
x
- 35) = (
2
x
- 35)
7
x
- 245 =
2
x
- 35
7
x
-
2
x
= 245 - 35
5
x
= 210
x
= 42
So present age of Christopher =
x
= 42 yrs
&
Present age of Ishaan =
2
x
= 84 yrs
Check your solution:
As 84 is 2 times of 42 so Ishaan is 2 times older than Christopher.
35 yrs ago, Christopher was (42 - 35) = 7 yrs old and Ishaan was (84 - 35) = 49 yrs old so Ishaan was 7 times older than Christopher then.

The definition of a rational number is:
Any number that can be made by building a fraction
using whole numbers.
You can make 0.123 that way. Here's the fraction: 123/1000
It's also handy to know that any number that's completely
written down using digits ... and a fraction bar or a decimal
point if they're needed ... is a rational number. This is not a
definition, and it doesn't cover all rational numbers, but it's
handy sometimes.
It's also handy to know that a decimal that has a set of digits
after the decimal point that repeats forever is a rational number,
even though you can't completely write it down (because it never
ends).
