3n - 1
One less is subtracting one.
Answer:
[tex]1-3[/tex]n
Step-by-step explanation:
One less 3 times a number.
1 less is 1-.
3 times a number would be 3n.
So, we get

Solve the equation for all real solutions in simplest form.
z^2 - 12z +9= -3
Answer:
Solving the equation for all real solutions in simplest form.
[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]
Step-by-step explanation:
We need to solve the equation for all real solutions in simplest form.
[tex]z^2 - 12z +9= -3[/tex]
First simplifying the equation:
[tex]z^2 - 12z +9+3= -3+3\\z^2 - 12z +12= 0[/tex]
Now, we can solve the equation using quadratic formula:
[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
we have a = 1, b=-12 and c=12
Putting values in formula and finding values of x
[tex]z=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\z=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(12)}}{2(1)}\\z=\frac{12\pm\sqrt{144-48}}{2}\\z=\frac{12\pm\sqrt{96}}{2}\\z=\frac{12\pm9.8}{2}\\z=\frac{12+9.8}{2}\:or\:z=\frac{12-9.8}{2}\\z=10.9\:or\:z=1.1[/tex]
So, we get value of z: z=10.9 or z=1.1
Solving the equation for all real solutions in simplest form.
[tex]z^2 - 12z +9= -3[/tex] we get [tex]\mathbf{z=10.9\: or\: z=1.1}[/tex]

A rectangle has an area of 6x^(2) + 7x - 3 square units. Which of the following could represent the perimeter of the rectangle in terms of x?
A. 2x + 3
B. 5x - 2
C. 10x + 4
D. 20x + 8
Answer:
C
Step-by-step explanation:
Area is W×L. The area of the rectangle is 6x^(2) + 7x - 3.
So we write that as 6x^(2) + 7x - 3 = W×L
We can factor 6x^(2) + 7x - 3 to see the width and length.
Then, you get (2x + 3) (3x - 1) = W × L
Now you have to values for width and length
The formula for perimeter is 2W + 2L, you can choose which is width and which is length
Next, substitute the values in the formula: 2(2x + 3) + 2(3x - 1) and solve it. Done! :)

Step-by-step explanation:
2x+13=-7x+28 =
Solutions:
x = 15
9
≈ 1.666667
Answer: x= 5/3
Step-by-step explanation:
subtract 13 from both sides of the equation
2x+13=-7x+28
2x+13-13=7x+28-13
simplify
subtract the numbers
2x=-7x+15
add 7x to both sides of the equation
2x+7x=-7x+15+7x
simplify
9x=15
divide
9x/9 = 15/9
simplify
Cancel terms that are in both the numerator and denominator
divide the numbers

can someone please help me with 13? there’s only two options you can see them in the picture
Answer:
The value of x is 5.8
Step-by-step explanation:
Here. we want to find the value of x
To do this, we need the appropriate trigonometric identity
As we can see 10 is the opposite as it faces the side given
x is the adjacent
The trigonometric identity relating opposite and adjacent is tan . Tan is the ratio of the opposite to the adjacent
Thus, mathematically;
Tan 60 = 10/x
x = 10/tan 60
x = 5.8
Which function is best represented by this graph
Answer:the potato is ugly
Step-by-step explanation:because it has marks
is this mapping a function or not a function ¿ i’ll mark brainlist
Answer:
Not a function
Step-by-step explanation:
If it is a function, every input has only one output. Meaning if we graph it, it will pass the vertical line test.
If you want to think about it in x and y, all values of x can only correspond to one value of y.
In this case, we can see that the x-value 6 has 2 corresponding y-values (5 and 10), therefore, this mapping is not a function.

A deck of cards has 52 cards. There are 4 suits, diamonds, hearts, clubs and spades. Each suit has 13 cards. What is the probability that I will randomly pick a 2, put it back, then randomly pick a 4?
Answer: 2%, ROUNDED
Step-by-step explanation:
You must divide 100 (whole percent) by 52 (Cards in a Deck) and you will get 1.92307692308%. But if we round it, we get 2%.
So the answer is 2%.

1. What is the initial balance in the account?
2. Is the account growing by the same number of dollars each year? Explain how you know.
3. A second investment account starts with $2,000 and grows by $150 each year.
4. How does the growth of balances in the two account balances compare?
Answer:
The opening balance is the amount of funds in a company's account at the beginning of a new financial period. It is the first entry in the accounts, either when a company is first starting up its accounts or after a year-end.
The initial balance in the account was approximately $4215.
How to find the initial balance in the account?The formula represents the relationship between the initial balance, the interest rate, the compounding period, and the time period.
To determine the initial balance in the account, we can use the formula for compound interest:
A = P(1 + r)ⁿ
where:
A = the ending balance
P = the initial balance
r = the annual interest rate as a decimal (5% = 0.05)
t = the number of years
Substituting the given values, we get:
[tex]5000 = P(1 + 0.05)^{(3.5)}[/tex]
[tex]5000 = P(1.05)^{(3.5)}[/tex]
Dividing both sides by [tex](1.05)^{(3.5)}[/tex], we get:
[tex]P = 5000/(1.05)^{(3.5)}[/tex]
Using a calculator, we get:
P ≈ $4215
Therefore, the initial balance in the account was approximately $4215.

The length of a rectangle is 1 7/9 in and its width is 3/4 of its length. Find the area of this rectangle
Given:
Length of the rectangle = 1 7/9 = 17/9.Width = 3/4 × length = 3/4 × 17/9 = 17/12.To find: The area of the rectangle.
Answer:
Formula to find the area of a rectangle = Length × Breadth.
Since we've calculated the length and breadth, let's substitute them directly.
17/9 × 17/12 = 289/108 = 2.67 [approx.]
Therefore, the area of the rectangle is 2.67 units.
Hope it helps. :)
An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 790 meters , and plane B was at an altitude of 1142 meters. Plane A losing altitude at 14 meters per second, and Plane B is losing altitude at 22 meters per second
Answer:
[tex]x=4.375[/tex]
Step-by-step explanation
From the question we are told
Plane A starts at altitude 790
Plane B starts at altitude 1142
Plane A losing altitude at 14 meters per second
Plane B is losing altitude at 22 meters per second
Generally the altitude of both plane is given by
Plane A= [tex]790-14x[/tex]
Plane B=[tex]1142-22x[/tex]
Therefore when they exist in the same altitude
[tex]790-14x[/tex] =[tex]1142-22x[/tex]
[tex]-350=-8x[/tex]
[tex]\frac{-350}{-8} =x[/tex]
Therefore
[tex]x=4.375[/tex]

Sorry that there's no work to show
Step-by-step explanation:
Answer:
y = [tex]-9x^2 + 54x + 63[/tex]
Step-by-step explanation:
An equation in standard form is;
[tex]y = ax^2 + bx + c[/tex]
y = -9( x + 1 ) ( x - 7 )
Distribute. multiply every term by another, and combine like terms;
y = -9 ( [tex]x^2 - 6x - 7[/tex] )
