Question

PLEASE HELP WILL GIVE BRAINLIEST!!!
Jamie and Linda are having a contest to see whose photo will get more "likes" on social media. Jamie's photo got 75 likes on the first day and is getting 36 more likes each day. Linda's likes can be modeled by the function f(x)=18(2)^x. Which statements are true? Select all that apply.


1) On day 4,Linda's photo will have over 100 more likes than Jamie's photo.
2) Jamie's photo gets more likes within the first three days than Linda's photo.
3) Jamie's photo will always have more likes than Linda's.
4) It takes Linda's photo 5 days to have more likes than Jamie's photo.
5) Linda's photo gets more likes within the first three days.

Answer 1

Answer:

  2) Jamie's photo gets more likes within the first three days than Linda's photo.

Step-by-step explanation:

Jamie's likes are modeled by the linear equation ...

  j(x) = 75 + 36x

Linda's are modeled by the given exponential equation ...

  f(x) = 18·2^x

It is convenient to have a calculator evaluate these equations for different numbers of days.

___

On day 4, Linda's photo has 69 more likes than Jamie's.

Jamie's photo has 39 more likes than Linda's in the first 3 days.

The photo with the most likes changes in the middle of Day 3, so neither photo "always" has more. It does not take 5 days for Linda's to have more.
