Answer:
n=16
Step-by-step explanation:
3 (n-4) = 36
3n -12=36
add twelve to both sides. because -12 + 12 is 0. and once you are at zero, you can cancel it out.
3n=48
divide by 3 on both sides
n=16

Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y - 3 = 2(x + 1)
Step-by-step explanation:
First, use rise over run to find the slope
(y2 - y1) / (x2 - x1)
(3 + 7) / (-1 + 6)
10 / 5
= 2
Now, plug in the slope and a point into the point slope formula:
y - y1 = m(x - x1)
y - 3 = 2(x + 1)
So, the equation in point slope form is y - 3 = 2(x + 1)

Solve the equation 1.5x + 18 =3
Answer:
x=10
Step-by-step explanation:
Simplifying
1.5x + 3 = 18
Reorder the terms:
3 + 1.5x = 18
Solving
3 + 1.5x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 1.5x = 18 + -3
Combine like terms: 3 + -3 = 0
0 + 1.5x = 18 + -3
1.5x = 18 + -3
Combine like terms: 18 + -3 = 15
1.5x = 15
Divide each side by '1.5'.
x = 10
Simplifying
x = 10
Given the quadratic expression, find the value of C to complete the square. Then write the expression as a binomial squared.
x^2-18x+C
Answer:

Answer:
81
Step-by-step explanation:
Move −18x, so
x^2+c−18x
To find the c value
c =(b/2)^2
divide the coefficient of x by 2 and square the result.
Divide 18 by 2
(-1⋅9)^2
Multiply −1 by 9
(−9)^2
Raise −9 to the power of 2 and get your answer

Find the value of the missing Angles:
Answer:
Angle 1 is 58 and Angle 2 is 32 because all triangles equal to 180 and where the lines bisect creates a 90 degree angle in each triangle. Add 90 and 32 together, then minus 122 from 180 and you get angle 1 and the angle across from angle 1. For angle 2, add 58 and 90, then subtract that from 180. You'll end up getting 32
[tex]2x^2-20x=x^{2} -19[/tex]
Answer:
x = 1, x = 19
Step-by-step explanation:
Given
2x² - 20x = x² - 19 ( subtract x² - 19 from both sides )
x² - 20x + 19 = 0 ← in standard form
(x - 1)(x - 19) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 19 = 0 ⇒ x = 19
True or False: An asymptote is a line in which a graph gets close to but never crosses.
True
False
Answer:
True
Step-by-step explanation:
An asymptote is, essentially, a line that a graph approaches, but does not intersect. For example, in the following graph of y = 1x y = 1 x , the line approaches the x-axis (y=0), but never touches it. No matter how far we go into infinity, the line will not actually reach y = 0, but will always get closer and closer.
The statement is true.
What is an asymptote?Asymptote is a line that a curve approaches as it moves towards infinity. Asymptotes. The curves visit these asymptotes but never overtake them.
An asymptote is a line along which the values of a function approaches but never reach, such that one or both of the or coordinates tend to positive or negative infinity. Therefore, the graph of a rational function never intersects any of its asymptotes.
Hence, the statement is true.

A hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry. What does the ratio 8:19 represent in this situation? Explain your reasoning. Include a model in your explanation.
Answer:
The 8:19 ratio is the bottles of cherry to the total amounts of bottles
Step-by-step explanation:
im not sure what a model would look like but here's one part of the question
The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
What is ratio?Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that a hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry.
Total number of bottles = 8 + 7 + 4 = 19
Total number of cherry bottles = 8
The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.
Therefore, the ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

You can invest $200 at 8% for 3 years. Find the simple interest.
Answer:
$48
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation
I = 200 × 0.08 × 3 = 48
I = $ 48.00
The simple interest accumulated

Arc OM [tex]=113[/tex]
Step-by-step explanation:
We know that Angle NPM is equal to 90 degrees.
Therefore, Angle KPM is also equal to 90 degrees.
We are told that Arc LM is equal to 67.
Thus, the measure for Arc KL is equal to [tex]90-67=23[/tex]
We also know that Angle OPN is equal to Angle KPL.
Therefore, the measure of Arc ON[tex]=23[/tex]

Karl set out to alaska on his truck the amount of fuel remaining in hi truck tank in liters as a function of distance driven in kilometers is graphed
What distance did Karl travel by the time he had 200 liters of fuel
Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.
Why it is and what is distance?
To determine the distance Karl traveled by the time he had 200 liters of fuel remaining in his truck, we need to examine the graph provided.
From the graph, we can see that when the fuel remaining in the truck tank is 200 liters, the corresponding distance driven is approximately 420 kilometers.
Therefore, Karl traveled 420 kilometers by the time he had 200 liters of fuel remaining in his truck.
Distance is the physical length between two points or objects. It is a scalar quantity that measures the amount of space between two locations, without regard to the direction of travel. Distance can be measured in various units such as meters, kilometers, miles, and so on.
In physics, distance is often distinguished from displacement, which is a vector quantity that measures the change in position of an object relative to its starting point.

One angle of a right triangle measures 34 degrees. What is the measure of the other acute angle
Answer:
56 degrees
Step-by-step explanation:
we know the right triangle has a 90 degree angle, so we add 90 + 34 to get 124
once we have that down we subtract 124 from 180 to get 56
the reason we subtract from 180 is because the sum of all the angles in a triangle equals 180
