Answer:
B. whole numbers, integers, rational numbers, natural numbers
Answer:
2) y = 0.5^x
Step-by-step explanation:
Plug in x coordinates to see which equation makes up the graph. We can see that the y values lower even after using positive numbers so this eliminates the possibility of 1) as that would make the y values increase. Starting with coordinates (-1, 2), let's plug these into 2):
y = 0.5^x
2 = 0.5^-1
2 = 2
Correct
Use another pair of coordinates to see if it still works:
(-2, 4)
4 = 0.5^-2
4 = 4
It does!
Check the other equations just to make sure this is the only option:
2 = 5^(- - 1)
Negative + Negative = Positive
2 = 5^1
2 = 5
Incorrect.
2 = 0.5^(- - 1)
2 = 0.5^1
2 = 0.5
Incorrect.
This means our first solution is the only solution.
So,
a.
Let
1. Alison be "a"
2. Kyle be "k"
3. Maurice be "m"
a = 2k
m = a + 5
m = 2k + 5
40 > 5k + 5
35 > 5k
7 > k
The relationship between k and m:
m = 2k + 5
19 > m
MAURICE CANNOT HAVE MORE THAN 19 VIDEO GAMES.
The percentage of Abigail's $2,325.00 monthly retirement income she has saved each month is 20%
What is the total savings for the nine months?
The fact that $627.75 saved for entertainment is only 15% of total savings means that we can determine the total savings in the period of nine months as shown below:
15%=$627.75
divide both sides by 15 to determine 1% of total savings
15%/15=$627.75/15
1%=$41.85
100%=$41.85*100
100% savings=$4,185.00
Now the total savings were saved over the period of 9 months, hence, monthly savings is determined as total savings divided by the number of months savings lasted
monthly savings=$4,185.00 /9
monthly savings=$465.00
monthly savings a percentage of monthly retirement income=$465.00/$2,325.00
monthly savings a percentage of monthly retirement income=20%
