Write and equation in slope-intercept form of the line that passes through the points
(-5,-12) and (1,6)
The equation is y=
Step 1: We need to use slope formula* to determine what m (or the slope) is.
[tex]m = \frac{6 - (-12)}{1 - (-5)}\\\\m = \frac{18}{6} = 3[/tex]
Step 2: Now we use this slope, ONE of the given points, and slope-intercept form** to determine b.
[tex]6 = 3(1) + b\\\\6 = 3 + b\\\\3 = b[/tex]
Step 3: The final answer can now be found by using the slope and y-intercept (or b) that we just found.
[tex]y = 3x + 3[/tex]
For Reference:
*Slope formula
[tex]m = \frac{y_{2} - y_1}{x_2 - x_1}[/tex]
*Slope-intercept Formula
[tex]y = mx + b[/tex]

A football stadium is capable of seating a maximum of m fans. For each game, the
amount of money that the stadium brings in as revenue is a function of the number of
people, n, in attendance. If each ticket costs $30.00, what is the domain of this function?
Answer:
The revenue depends on the number of people n that purchases tickets, knowing that each ticket costs $30.00, the total revenue will be:
f(n) = $30.00*n
Now, we also know that the stadium is capable of seating a maximum of m fans, so the maximum possible value for n is m.
Now, for the function f(n), we have that:
The domain is the set of the possible values of n
The range is the set of the possible values of f(n).
We want to find the domain.
First, the minimum possible value of n is 0, the case where nobody purchases a ticket.
The maximum possible value of n is m, this is the case where the stadium is full.
Then the domain will be:
D= {n,m ∈ Z, 0 ≤ n ≤ m}
Where we imposed that n must be an integer number because n represents a whole quantity.
The domain of the function should be [tex]0\leq n\leq m[/tex] where n and m are integers because they represent the number of people.
Given information:
A football stadium is capable of seating a maximum of m fans.
People attending the game are n.
The cost of each ticket is $30.
The amount of money that the stadium brings in as revenue is a function of the number of people, n.
So, the money will be calculated based on the attendance of people which implies that n will be the independent variable of the function.
So, the revenue generated can be written as,
[tex]f(x)=30n[/tex]
Here, the value of n represents the domain of the function.
Now, the maximum number of people allowed in the stadium is m as there are only m seats.
Therefore, the domain of the function should be [tex]0\leq n\leq m[/tex] where n and m are integers because they represent the number of people.

Point Lis a centroid of the triangle FWD, If RL = 54 cm, what is RD?
O 81 cm
O 162 cm
O 100 cm
O 58 cm
Answer:
RD = 162 cm
Step-by-step explanation:
LD = 2 RL = 2* 54 = 108
RD = RL + LD
RD = 54 + 108
RD = 162 cm
The length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have:
Point L is a centroid of the triangle FWD, If RL = 54 cm
From the centroid definition:
LD = 2RL
LD = 2×54 = 108 cm
RD = RL + LD
RD = 54 + 108
RD = 162 cm
Thus, the length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.

Luis rides his bicycle 3/4 mile in 15 minutes, or 1/4 hour, along the bike trail. Assuming he rides at a constant rate, what is his speed, in miles per hour?
Answer: 3
This is because 15 times 4 equals 60 and that is equal to 1 hour, well when your multiplying fractions what you do to the bottom you have to do to the top so multiply 3 times 4 thats 12 and now you have 12/4 and that is equal to 3.
an item is regularly priced at $95. it is on sale for 40% off the regular price. what is the sale price?
Answer:
The sale price is $57.
Step-by-step explanation:
Given that the sale is 40% discount so you will have to pay for the remaining 60%. In order to find the sale price, you will have to multiply 60% with the regular price:
[tex] \frac{60}{100} \times 95 = 57[/tex]
Find the slope of:
(-4,5) and (-4, 2)
The slope is undefined.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction
Given points (-4 ,5) and (-4 ,2).
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (2-5) / (-4+ 4)
here, (x₂ - x₁) =0
That means the slope is undefined.
Therefore, the slope is undefined.

If ray ST bisects ∠RSU and m∠TSU=43°, find m∠RSU.
Answer: 86 degrees
Explanation:
Angle TSU is formed when we bisect angle RSU. Recall that bisect means to cut in half. So TSU is half of RSU. Put another way, RSU is twice that of TSU.
angle RSU = 2*(angle TSU)
angle RSU = 2*43
angle RSU = 86

Which linear inequality is represented by the graph?
1 y 1/2x + 2

Answer:
A
Step-by-step explanation:
The linear equation of inequality is y ≤ ( x/2 ) + 2
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The x intercept of the equation is when y = 0
So , A ( -4 , 0 ) is the x intercept
And , the y intercept is when x = 0
So , B ( 2 , 0 ) is the y intercept
Therefore , the inequality is y ≤ ( x/2 ) + 2 and the graph is plotted
Hence , the inequality is y ≤ ( x/2 ) + 2

What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The number of batch recipe calls for 1 / 2 lb of flour = 1 batch
And to calculate the number of batches , we use
The number of batch recipe calls for 1 lb of flour will be
1 / 2 lb of flours = 1 batch
Multiplying by 2 on both sides , we find the number of batches for 1 lb of flour
Therefore , 1 / 2 x 2 = 1 x 2
1 lb of flour = 2 batches
3 / 4 lb of flour is 1 x 3 / 4 = 2 x 3 / 4
= 3 / 2 batches
= 1.5 batches
1 / 4 lb of flour is 1 x 1 / 4 = 2 x 1 / 4
= 1 / 2 batches
= 0.5 batch
Hence , The number of batches that can be made with 1 lb , 3 / 4 lb and 1 / 4 lb are 2 batches , 1.5 batches and 0.5 batch respectively

Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet. The second rectangle has a width of 8 feet and a length of x + 2 feet. What is the sum of the two perimeters?
Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.
Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.
