Answer:
x> − 15, could be wrong but i hope this helped!
Step-by-step explanation:
Answer:
The percentage of people going to the people in week 4 compared to week 1 decreased by 25%.
Step-by-step explanation:
Week 1: 1,040 people
Week 2: 105 fewer people
1040 - 105 = 935 people
Week 3: 135 more people
935 + 135 = 1070 people
Week 4: 290 fewer people
1070 - 290 = 780 people
So, there were 260 fewer people, going to the pool in those 4 weeks compared to week 1.
Now, we must find the percentage change.
x/100 = 780/1040
Cross multiply.
1040x = 78000
Divide both sides by 1040 to leave x by itself on one side.
x = 78000/1040
x = 75%
This means only 75% of the total people from week one were going to the pool in week four. Therefore, there was a 25% decrease in the number of people who went to the pool over these four weeks.
It decreased by 25% every year.
if you multiply a number by a decimal you will get a smaller number than you originally had. for example, if you multiply 95 by .75 you will get 71.25 it is decreasing but only 25%
Hmm,
the absolute value makes whaterver inside positive
so
find whre the abslte value is 0
1.6x-2=0
1.6x=2
x=2/1.6
x=1.25
as x approaches 1.25, the function decreases
so from left to right
from the left to right, from -ifninty to 1.25, it is decreasing
from 1.25 to infinity, it is increasing
so it is increasing in the interval (1.25,∞)
