SOMEONE PLEASE HELP ME

The equation is C, and the correct answer is 6 (D)

Step-by-step explanation:

We first look for the correct equation. If Matt charges 9 dollars per hour, and earned a total of 99, then we known that 9*the number of hours = 99. Moving on, we know that he babysat Friday night for 5 hours, but we don't know the number on Saturday. BUT we do know that 5+saturday hours = total number of hours. Putting this into a formula, we get 9(5+x (where x = #of hours worked on saturday) = 99(total number)

Our final equation is 9(5+x)=99.

Solving this by dividing both sides by 9, we get 5+x=11. Subtracting 5 from both sides gives us x = 6.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
