Answer:
x = 4Step-by-step explanation:
x - 2 x 2 = 8
x times 2 = 8
x = 4
Find the inverse of the function. *
g(x) = 1/x - 2
g^(-1) => x = 1/g(x) - 2
g^(-1) => x + 2 = 1/g(x)
g^(-1) => g(x)(x + 2) = 1
g^(-1) => g(x) = 1/(x + 2)
Answer: D. g^(-1) = 1/(x + 2)

Step-by-step explanation:
A basketball player scores p points each quarter for each of the four quarters of the regular game and then scores 5 points in overtime. Which expression represents the total number of points the basketball player scores during all four quarters and overtime? a. 4(p+5)4 b. 4p+54 c. 5(p+4)5 d. 5p+4
Answer:
4p+ 5
Step-by-step explanation:
Given that :
Point stored per quarter = p
Number of quarters = 4
Point scored in overtime = 5
total number of points the basketball player scores during all four quarters and overtime?
(Point scored per quarter * number of quarters) + point scored in overtime
(p * 4) + 5
4p + 5
How can real life problems involving one variable be modeled and solved?
Answer:
Writing an equation to model a real-world problem is often easier when you take the information given in the problem and express it in verbal form by using a few key words. This is very similar to translating verbal phrases into variable expressions. The difference is you will be translating a verbal sentence into an equation. Then, you can solve the equation using inverse operations.
Let’s look at an example.
Monica purchased a pair of tennis shoes that had this sticker on the bottom of the shoe.
$99.00$65.99
Use a verbal model to write and solve an equation to determine the amount of money Monica saved by purchasing the shoes on sale.
First, write a verbal model to represent the problem.
Verbal Model:
Sales Price+Amount Saved=Original Price
Next, name the variable.
Let ‘
s
’ represent the amount saved.
Next, solve the equation you have written. Remember an equation is like a balance scale. To keep the scale balanced, what you do to one side of the equation you must also do to the other side. When solving an equation your goal is to isolate the variable on one side of the equation and the numerical terms on the other side. This is done by performing inverse operations.
65.99+s=99.00
First, isolate the variable ‘
s
’ by subtracting 65.99 from both sides of the equation. Subtraction is the inverse of addition.
65.99−65.99+s=99.00−65.99
Next, simplify each side.
s=33.01
The answer is $33.01.
A variable can be any element that we can, in some way, change.
The general form of modeling and solving real life problems that involve one variable is:
Identify what the variable is and define it.Write the equation.Isolate the variable on one side of the equation.So for example, something that we can define with a variable is "How many of one type of item we can buy if we know its price"
For example, if we know that a shirt costs $10, then the price of x of these shirts is:
y = $10*x
Now, if you know how much money you have, you can use this equation to find how many shirts you can buy.
For example, you know that you have $20, then y = $20
$20 = $10*x
To solve this we need to isolate the variable on one side:
$20/$10 = x
2 = x
You can buy two shirts.
Now, the general form of modeling and solving real life problems that involve one variable is:

The lager of two numbers is 15 more than three times the smaller.If the sum of the two numbers is 63,find the numbers
Answer:
The numbers are:
The smaller number = 12The larger number = 51Step-by-step explanation:
Let 'x' be the smaller number
As the lager of two numbers is 15 more than three times the smaller. so,
The larger number = 3x+15
As the sum of the two numbers is 63, so the equation becomes
[tex]x + 3x + 15 = 63[/tex]
[tex]x+3x=63-15[/tex]
[tex]4x=48[/tex]
Divide both sides of the equation by
[tex]\frac{4x}{4}=\frac{48}{4}[/tex]
[tex]x = 12[/tex]
Therefore,
The smaller number = x = 12
The larger number = 3x+15 = 3(12) + 15 = 36+15 = 51
Hence, the numbers are:
The smaller number = 12The larger number = 51Justin uses 2/3

On first day of every month, Katie gets 590 phones to repair. She repairs 15 phones every day after that day. How many phones does she
have left to repair at the end of the 19 day of the month?
Answer:
305
Step-by-step explanation:
If she is at day 19, that means you have to multiply 15 (phones repaired each day) times 19 (19th day) in order to get how many phones she has counted which is 285. To find how much she has left, you have to subtract 285 from 590 which gets you 305.

please help lol.. i have to find the value of x..
Answer:
x = 31
Step-by-step explanation:
The sum of the internal angles = 180°
then:
2x-5 + x+10 + 2x+20 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155/5
x = 31
Check:
2*31 - 5 + 31+10 + 2*31 + 20 = 180
62-5 + 41 + 62+20 = 180
57 + 41 + 82 = 180

Step-by-step explanation:
The mnemonic SOA CAH TOA reminds you of the relationship between angles and sides of a right triangle. Here, we have the side opposite the 58° angle, and we want to know the side adjacent. The relevant relation is ...
Tan = Opposite/Adjacent
tan(58°) = (10 feet)/x
x = (10 feet)/tan(58°) ≈ 6.249 feet

Answer:
1) x ≅ 51.34°
2) y ≅ 38.66°
Step-by-step explanation:
In the right triangle given in the figure
∵ The triangle has a right angle
∴ Angles x and y are acute angles and the sum of their measures is 90°
→ By using the trigonometry function tan
∵ tan(x) = opposite side to x/adjacent side to x
∵ The opposite side to x = 10
∵ The adjacent side to x = 8
→ Substitute them in the rule above
∴ tan(x) = [tex]\frac{10}{8}[/tex] = [tex]\frac{5}{4}[/tex]
→ Use the inverse of tan to find x
∵ x = [tex]tan^{-1}[/tex]([tex]\frac{5}{4}[/tex])
∴ x = 51.34019175
∴ x ≅ 51.34°
∵ x + y = 90°
∴ 51.34 + y = 90
→ Subtract 51.34 from both sides
∴ y ≅ 38.66°
