Karen is ten years older than gary today. two years from now, karen will be three times as old as old as gary will be. how old is gary today. use algebra to solve

Didn't use algebra but Gary would be 3 and Karen would be 13 so in 2 years Gary would be 5 and Karen would be 15 and 5 x 3 = 15 so ya.

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.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
