Put the function as an equation:
y = 2x + 1
Then move x to the left and y to the right;
x = 2y + 1
Then solve for y;
y = x/2 - 1/2
f^-1(x) = y
f^-1(x) = x/2 - 1/2
Calculate the slope of the line that passes through the labeled points on the graph.
m=(Y2-Y1)/(X2-X1)
(1.) m=(2-(-1))/(-2-3) = 3/-5 = -3/5
(2.) m=(-2-1)/(-3-2) = -3/-5 = 3/5

There are 21 more days before the first big winter storm and the squirrel collects 12 acorns a day, how far away from her original amount will the squirrel be? Explain. What should the squirrel do to the bear to get even with him for eating all those acorns?
The squirrel will collect a total of 252 acorns in the 21 days before the winter storm. This is calculated by multiplying 12 acorns/day by 21 days. Instead of retaliating against a bear, the squirrel should focus on preparing for winter.
Explanation:If the squirrel collects 12 acorns a day and there are 21 more days until the big winter storm, we can calculate the total number of acorns the squirrel will collect. We do this by multiplying the number of acorns collected per day by the number of days remaining, which gives us:
12 acorns/day × 21 days = 252 acorns
After 21 days, the squirrel will have accumulated 252 acorns more than the original amount she had before the given 21-day period.
Regarding what the squirrel should do to get even with the bear for eating the acorns, it's important to remember that animals in nature often have to deal with challenges like this. The squirrel could focus on collecting more acorns, perhaps finding a better hiding place to store them, to prepare for the winter storm. However, revenge actions, such as retaliating against the bear, are not advisable nor part of natural behaviors in wildlife, and focusing on preparations for winter would be a more practical approach for survival.

Given that 1 kilogram weighs approximately 22 pounds, rewrite 10 pounds as an equivalent number of kilograms
Answer:
0.4545 kgs.
Step-by-step explanation:
Given that 1 kg weighs approximately 22 pounds.
i.e. 1kg= 22 lbs.
We can use this to convert lbs into kg.
22 lbs = 1 kg
Hence 1 lb = 1/22 = 0.04545 kg
Now to find out the equivalent weight for 10lbs,
we have conversion factor as 1 lb= 0.04545 kg
Hence 10 lbs = 10(0.04545) = 0.4545 kgs
Hence 10 pounds written in equivalent kgs would be0.4545 kgs.

2b+4=-18-9b ; solving equations with variables on both sides
To solve this, first add -9b on both sides of the equation to get the variable on only one side of the equation.
2b+4=-18-9b
2b+9b+4=-18-9b+9b
11b+4=-18
Then subtract 4 from both sides of the equation.
11b+4=-18
11b+4-4=-18-4

A) 68%
B) 37%
C) 31%
D) 46%
Answer:
B) 37%
Step-by-step explanation:
Given,
The total base pay and commission = $ 52561,
While, base pay = $ 23690,
So, the amount of commision = Total base pay and commission - base pay = $ 52561- $ 23690 = $ 28871,
Also, total sale = $77,300,
Hence, the rate of the commission( in percentage )
[tex]=\frac{Commission}{Sale}\times 100[/tex]
[tex]=\frac{28871}{77300}\times 100[/tex]

As you walk to your car, you notice that your tire is nearly flat. The initial psi level yesterday was 38, but it is now only 35 today. If this trend continues and the tire keeps losing the same percentage of air, how much should be left at the end of the week?(7 days later)
Answer:
Air left in the Tyre after 1 week = 21.36 psi
Explanation:
Initial psi level = 38 psi
Psi level after 1 day = 35 psi
Percentage of remaining of air per day = (35/38)*100 = 92.10%
Ratio of remaining air per day = 0.921
Ratio of remaining air after 7 days = 0.921⁷ = 0.562
Percentage of remaining air after 7 days = 56.21%
Air left in the Tyre after 1 week = 38*56.21/100 = 21.36 psi
The student's question is about calculating the expected tire pressure at the end of a week, based on a consistent daily percentage decrease from an initial 38 psi to 35 psi. It involves a mathematical analysis using exponential decay, which is a high school level mathematics topic.
The question involves finding the projected tire pressure after a week given an initial pressure of 38 psi that has decreased to 35 psi in one day. The percentage decrease from 38 psi to 35 psi is calculated first, and then this percentage is consistently applied to find the remaining pressure after 7 days using exponential decay since the tire loses the same percentage of air each day.
Step 1: Calculate the percentage decrease.
Initial pressure (yesterday) = 38 psi
Current pressure (today) = 35 psi
Percentage decrease = ((38 - 35) / 38) x 100%
Step 2: Apply this percentage decrease for 7 days using the formula:
Pn = P0 * (1 - percentage decrease)^n
Where:
Pn is the pressure after n days
P0 is the initial pressure
n is the number of days
By calculating P7, we can find the expected pressure at the end of the week.
Step 3: Substitute the known values and calculate the expected pressure after 7 days.
