Find the inverse of the function f f (x )
equals 9 x + 7
Note: Your question seems a little bit ambiguous. So, I am assuming the given function f(x)=9x+7.
Thus, I am solving based on it. It would still clear your concept.
Answer:
The inverse of f(x)=9x+7
[tex]\frac{x-7}{9}[/tex]Step-by-step explanation:
Given the function
[tex]f(x)=9 x + 7[/tex]
A function g is the inverse of function f if for y=f(x), x=g(y)
Replace x with y
[tex]x=9y+7[/tex]
solve for y
[tex]9y=x-7[/tex]
[tex]y=\:\frac{x-7}{9}[/tex]
Therefore,
The inverse of f(x)=9x+7 is:
[tex]\frac{x-7}{9}[/tex]i.e.
[tex]\mathrm{Inverse\:of}\:9x+7:\quad \frac{x-7}{9}[/tex]

A car is traveling at a steady speed. It travels1 3/4 miles in 2 1/3 minutes. How far will it travel in 49 minutes ? In 1 hour ?
Answer:
[tex]36\frac{3}{4} miles[/tex] and [tex]45 miles[/tex] respectively
Step-by-step explanation:
There are a few ways to solve this
First we find the speed of the car, which is the distance divided by time [tex]speed=\frac{distance}{time}[/tex] now distance is [tex]1\frac{3}{4} =\frac{7}{4} miles[/tex] and the time is [tex]2\frac{1}{3} =\frac{7}{3} minutes[/tex] Then [tex]speed=\frac{7}{4} /\frac{7}{3}=\frac{7}{4} *\frac{3}{7}=\frac{3}{4} miles/minute[/tex] Using this speed, we just find the distance using different time valuesrewriting the formula so the distance is the subject gives [tex]distance=speed*time[/tex] So for time as 49 minutes we have [tex]distance=(\frac{3}{4}miles/minute)*(49minutes)=36\frac{3}{4} miles[/tex] Then for time as 1 hour which is 60 minutes we have [tex]distance=(\frac{3}{4}miles/minute)*(60minutes)=45miles[/tex]Raina purchased a prepaid phone card for $25.

If the graph of f(x) = x is shifted up 9 units, what would be the equation of the new graph?
A. g(x) = f(x) – 9
B. g(x)=f(x – 9)
c. g(x) = 9 - f(x)
D. g(x) = f(x) + 9
Answer:
b. g (x) = 9f (0)
Step-by-step explanation:
hope it help
==========================================================
Explanation:
Replace f(x) with y. This is valid because both represent outputs of a function. This means f(x) + 9 is the same as y+9, which means "move every point up 9 units".
For instance, the point (1,1) turns into (1,10) after moving it up 9 units. Here we added 9 to the y coordinate while keeping the x coordinate the same. You can write the translation rule as [tex](x,y) \to (x, y+9)[/tex]

In the morning, the temperature was 15∘F. During the day, the temperature fell 37 degrees. Which expression shows how to find the temperature at the end of the day?
Answer:
- 22°F
Step-by-step explanation:
Given that :
Morning temperature = 15°F
Change in temperature = fall by 37 degree
The temperature of the end of the day:
Morning temperature + (change in temperature)
Fall by 37° = decrease in temperature by 37° = - 37°
15°F + (-37°F)
15°F - 37°F
= - 22°F

what is an equation of the line that passes through the points (0,8) and (6,7)? Put your answer in fully reduced form.
Step-by-step explanation:
Hey there!
The given points are;(0,8) and (6,7).
Note: Remember to use two point formula for finding the eqaution which has two points.
Or
You can find Slope through the slope formula and then use one point formula to find eqaution.
Now, let's use here two point formula.
The formula is;
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Now, keep all values.
[tex](y - 8) = \frac{7 - 8}{6 - 0} ( x - 0) [/tex]
Simplify it.
[tex](y - 8) = - \frac{1}{6} (x)[/tex]
[tex]y - 8 = - \frac{1}{6} x[/tex]
[tex]or \: \frac{1}{6} x + y - 8 = 0[/tex]
Therefore, the eqaution is; (1/6)X + y - 8 = 0.

Musa and Akiola together invest $52,000 in a business and agree to share the profit in the ratio of their investment. Musa receives $5,000 and Akiola receives $8,000 as a profit at the end of the first year. How much did each invest?
Money invested by Musa and Akiola together in a buisness=$52,000
Profit earned by Musa =$5,000
Profit earned by Akiola=$8,000
Ratio of profit earned by Musa to the profit earned by Akiola:-
[tex] = 5000 : 8000[/tex]
Now, let us simplify the ratio of their profits:-
[tex] = 5000 : 8000[/tex]
[tex] = \frac{5000}{8000} [/tex]
[tex] = \frac{5000 \div 1000}{8000 \div 1000} [/tex]
[tex] = \frac{5}{8} [/tex]
[tex] = \bold{ 5 : 8}[/tex]
Thus, the ratio of profit earned by Musa to the profit earned by Akiola=5:8
It is given that :-The ratio of profit earned by Musa to the profit earned by Akiola=The ratio of money invested by Musa to the money invested by Akiola
Which means :-The ratio of money invested by Musa to the money invested by Akiola=5:8
Then :-Money invested by Musa :-
[tex] = \frac{5}{5 + 8} \: \: of \: \: 52000[/tex]
[tex] = \frac{5}{13} \: \: of \: \: 52000[/tex]
[tex] = \frac{5}{13} \times 52000[/tex]
[tex] = \frac{5 \times 52000}{13} [/tex]
[tex] = \frac{260000}{13} [/tex]
[tex] = \bold{\$ \: 20,000}[/tex]
Thus, the money invested by Musa =$20,000
Money invested by Akiola:-
[tex] = \frac{8}{5 + 8} \: \: of \: \: 52000[/tex]
[tex] = \frac{8}{13} \: \: of \: \: 52000[/tex]
[tex] = \frac{8}{13} \times 52000[/tex]
[tex] = \frac{8 \times 52000}{13} [/tex]
[tex] = \frac{416000}{13} [/tex]
[tex] = \bold{ \$ \: 32,000}[/tex]
Thus, the money invested by Akiola =$32,000
As the sum of their investments add up to form $52,000 we can conclude that we have found out the correct amount of money each of them invested in the business.
Therefore, the money invested by Musa in the buisness =$20,000 and the money invested by Akiola in the buisness=$32,000

A family of four goes out to dinner. The total price for their food and drink purchases is $54.88. The sales tax is 5%. How will the waitress determine the amount of tax to add to the bill?
Answer:
Multiple the total by .10 or 10% (move the decimal place one to the left). Doing that gives 10% of the total or $5.48. To get 5%, divide that number in half for $2.74.
Step-by-step explanation:
This is the same for determining a tip of 20%. Move the decimal one to the left and double that number. For 15%, move the decimal place one to the left. There's 10%, half that, and add the two numbers together for 15%.
-2 (h - 5) < -12
Please some help me I don’t understand :(
Answer:
[tex]h>11[/tex]
Step-by-step explanation:
We have the inequality:
[tex]-2(h-5)<-12[/tex]
Solve. Divide both sides by -2. Since we are dividing by a negative, we must flip the inequality sign. Thus:
[tex]h-5>6[/tex]
Add 5 to both sides:
[tex]h>11[/tex]
Therefore, our solution is all numbers greater than 11 .
This means that if we substitute any number greater than 11 into our original inequality, the inequality will be true.

Answer:
Following are the solution to this question:
Step-by-step explanation:
An alternative black, white, and grey design of the tile is also desired. She needs her color scheme to suit the top boundary of the tile. Therefore, the central tile paint should be grey to ensure a white top boundary. To ensure, that perhaps the outer end is white, the color of the center tile shall be dark.

Mary made $165 for 11 hours of work. At the same rate, how many hours would she have to work to make $75? hours
Answer:
5 Hours
Step-by-step explanation:
165/11=$15 an hour
75/15=5 hours
Answer:
5 Hours
Step-by-step explanation:
First you have to find the unit rate which you would find by doing 165 divided by 11 which would equal 15 dollars per hour. Then you do 75 divided by 15 which is 5 meaning it would take 5 hours to make 75 dollars.

I need help solving the following question...
Answer: -10, 2
Step-by-step explanation:
To find the next two numbers, we first need to determine the pattern. We can see that the next number is the result of the previous number divided by -5. This tells us we need to divide 50 by -5 and that solution by -5 also.
50÷(-5)=-10
-10÷(-5)=2
Now, we know the next two numbers are -10 and 2.
Answer:
-10 and 2
Step-by-step explanation:
To find the next two numbers, you have to find what operation is being applied to the given numbers. If we look at the numbers, we can see that the absolute value is getting smaller, which means they are decreasing. However, they are decreasing at an even rate, meaning that the numbers are being divided rather than subtracted. So, let's find what number 1250 was divided by to equal -250:
1250/x = -250
Multiply both sides by x to isolate it:
1250 = -250x
Divide both sides by -250 to isolate x:
-5 = x
Each number in the pattern is divided by -5 to find the next number in the pattern. Now that we know this, we can find the next two numbers:
50/-5 = -10
-10 is one of the numbers.
-10/-5 = 2
2 is the other number.
Hope this helps :)
