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]
Write an expression to find how many times Jason will blink in 60 minutes if he continues to blink 19 times a minute.
Given that f(x) =
2x-5, find the
value of x that
makes f(x) = 15.
Select one:
a. 5
b. 10
c. 20
d. 25
Answer:
Answer is b or 10.
Step-by-step explanation:
The reason for this is that you will just plug in all the answers in x and the answer has to match 15.
So...
2(10) - 5 = 15
15 = 15
This is true so the answer is 10.

Answer:
If f(x)=g(x), the solution is x=-2
Step-by-step explanation:
We are given:
[tex]f(x)=3x+3\\g(x)= (-1/2)x-4[/tex]
We need to find the solution if f(x)=g(x)
Now solving for f(x)=g(x)
[tex]f(x)=g(x)\\3x+3=(-\frac{1}{2}x)-4\\3x+3=-\frac{1}{2}x-4\\3x+\frac{1}{2}x=-4-3\\\frac{3x*2+x}{2}=-7\\\frac{6x+x}{2}=-7\\\frac{7x}{2}=-7\\x=-7*\frac{2}{7}\\x=-2[/tex]
If f(x)=g(x), the solution is x=-2

Answer:
[tex]d=4\sqrt{5}\approx8.94[/tex]
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Let (-1, -2) be (x₁, y₁) and let (-9, 2) be (x₂, y₂).
Substitute appropriately:
[tex]d=\sqrt{(-9-(-1))^2+(2-(-2))^2[/tex]
Evaluate:
[tex]d=\sqrt{(-8)^2+(4)^2[/tex]
Square and evaluate:
[tex]d=\sqrt{64+16}=\sqrt{80}=4\sqrt{5}\approx8.94[/tex]
Therefore, the distance between the two points is approximately 8.94 units.

Isosceles triangle:It is a triangle with two equal angles or two equal side.Angles opposite to the equal sides of an isosceles triangle are also equal.Angle bisector is perpendicular to the base in an isosceles triangle.What is angle bisector?"It is a ray/line that divides an angle into two equal parts."
From figure,
BD is perpendicular to the base AC.
Since BD is an angle bisector,
⇒ 4x - 8 = 20
⇒ 4x = 20 + 8
⇒ 4x = 28
⇒ x = 28/4
⇒ x = 7
Therefore, the range of the values for x would be,
6 < x < 8.

If a is positive and c is negative, how many real-number solutions will the equation ax^2+bx+c=0 have? Explain. Heeeellllllllllllllllllppppppppppp!!, Please help me!
Answer:
If a is positive and c is negative, there will be 2 real numbers solutions
Step-by-step explanation:
To get this, we need to get the value of the discriminant
Mathematically;
D = b^2 - 4ac
In this case , since a is positive and c is negative;
Then b^2 - 4ac will be positive
Thus b^2 - 4ac will be greater than zero
If the discriminant D is greater than zero, then we should expect 2 real-number solutions

-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.
with some functions, the value of the
dependent variable decreases as the value of the
independent variable increases. What is a real-world
example of this ?
Answer and explanation:
This is an example of negative correlation/inverse relationship between two variables. A negative correlation between two variables, independent and dependent variable, occurs when increase in one variable is associated with decrease in the other. In other words, the two variables tend to go in opposite direction.
The independent variable is the variable that causes a change in the dependent variable. For example, an increase in the independent variable in an inverse relationship will bring about a decrease in the dependent variable.
A good real world example is the increase in inflation and the decrease in purchasing power of money.
An equation for this could be
Y=-0.2(x)
Where y is dependent variable purchasing power and x is independent variable inflation
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]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%.

Write an equation in the form y=mx for the proportional relationship that passes through the points (2, -15) and (6, -45).
Answer:
Y=-15/2x
Step-by-step explanation:
The equation of line in the form y=mx is y=-15/2x
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given coordinates:
(2, -15) and (6, -45).
Now, slope for the equation
slope= [tex](y_2 - y_1)/ (x_2- x_1)[/tex]
slope= (-45 - (-15))/ (6 - 2)
slope= (-45 + 15)/ 4
slope= -30/4
slope= -15/2
Hence, the equation of line in the form y=mx is y=-15/2x

An energy drink contains 60% of the recommended daily amount of carbohydrates. If it contains 180 grams of carbohydrates, what is the recommended daily amount of carbohydrates
Given:
An energy drink contains 60% of the recommended daily amount of carbohydrates.
It contains 180 grams of carbohydrates.
To find:
The recommended daily amount of carbohydrates.
Solution:
Let x be the recommended daily amount of carbohydrates.
It contains 180 grams of carbohydrates.
So, according to the question,
60% of x = 180
[tex]\dfrac{60}{100}x=180[/tex]
[tex]0.6x=180[/tex]
Divide both sides by 0.6.
[tex]x=\dfrac{180}{0.6}[/tex]
[tex]x=300[/tex]
Therefore, the recommended daily amount of carbohydrates is 300 grams.
