To find the slope of the line, I will be showing you the table method.
To find the slope of the line using the table method,
we start by making a table for our ordered pairs.
We will put the x values in the left column
and the y values in the right column.
Our first ordered pair is (3, 8), so we put a
3 in the x column and a 8 in the y column.
Our second ordered pair is (1, -2), so we put a
1 in the x column and a -2 in the y column.
Next, remember that the slope or m, is always equal to
the rate of change or the change in y over the change in x.
Using our table, we can see that the y values
go from 8 to -2 so the change in y is -10.
The x values go from 3 to 1 so the change in x is 2.
Therefore, the rate of change, or the change in y
over the change in x is -10/2 which reduces to 5.
This means that the slope is also equal to 5.

Polygon JKLM is drawn with vertices J(−4, −3), K(−4, −6), L(−1, −6), M(−1, −3). Determine the image coordinates of L′ if the pre-image is reflected across y = −3.
L′(−3, 6)
L′(−1, 6)
L′(−1, 0)
L′(1, 0)
Answers
To reflect the pre-image across y = -3, we need to flip the entire polygon over the line y = -3. This means that the x-coordinates of each point will remain the same, but the y-coordinates will be reflected across the line.The y-coordinate of point L is -6, which is 3 units below the line y = -3. When reflected, this point will be 3 units above the line y = -3. Therefore, the image coordinates of L' will be (−1, 0), since the x-coordinate of L is -1 and the y-coordinate of L' is 3 units above y = -3, which is 0.So, the image coordinates of L' are (−1, 0).

Jason needs 2 ½ pounds of potatoes to feed 15 people at his Friendsgiving dinner. But, his friends just called and told him they’re each bringing more friends. How many pounds of potatoes will need to feed 50 people? Explain your reasoning.
Answers
Answer:
8 1/3, eight and one over three.
Step-by-step explanation:
First lets find the rate by dividing 15 by 2.5 You will get 6 meaning that six people eat 1 pound each. Now lets divide 6 from 6 and 1. This means that 1 person will eat 1/6 of the pounds of the potatoe. Then we can do 50 times 1/6 and we will get 8.3333. This means that Jason needs 8 and 1/3 pounds of potatoes to feed 50 people.

A. To make a right triangle in the center, the area of the smaller two squares must add to equal the area of the largest square.
Step-by-step explanation: The Pythagorean Theorem states that the square of the length of the two smaller side of a triangle should add up to the square of the largest side. Since the area of a square is basically square of one of its sides, it means if we the are of the two smaller square add up to the are of the largest square.

A community has an empty field ready for development and plans to place a playground in the center. A model of the plan for the project is shown. A large rectangle with dimensions of 21 feet by 36 feet. Inside it is a smaller rectangle with dimensions of 15 feet by 12 feet. How much area is left for development in the field outside the playground? 756 ft2 576 ft2 288 ft2 180 ft2
Answers
Answer:
576 ft²
Step-by-step explanation:
Large rectangle:
21·36=756
Smaller rectangle:
15·12=180
Find leftover area:
756-180
=576 ft²
Hope this helps! :)
Answer:
The area that is left for development in the field outside the playground is 576 ft².
Step-by-step explanation:
To calculate the area left for development in the field outside the playground, we need to subtract the area of the smaller rectangle from the area of the larger rectangle.
The area of a rectangle is the product of its width and length:
\(\boxed{\sf Area\;of\;a\;rectangle=width \times length}\)
The dimensions of the larger rectangle are:
width = 21 ftlength = 36 ftThe dimensions of the smaller rectangle are:
width = 15 ftlength = 12 ftTherefore, the development area can be calculated as follows:
\(\begin{aligned}\sf Development \;area&=\sf Area_{large\;rectangle}-Area_{small\;rectangle}\\\\&=(21 \times 36)-(15 \times 12)\\\\&=756-180\\\\&=576\; \sf ft^2\end{aligned}\)
Therefore, the area that is left for development in the field outside the playground is 576 ft².

A truck drove 208 miles on 5 gallons of gas. How far should it be able to go on a full, 11-gallon tank?
Answers
Answer:
457.6
Step-by-step explanation:
if he drove 208 on 5 gallons, 208/5 =41.6 miles per gallon. 41.6*11= 457.6
Answer:
457.6 miles
Step-by-step explanation:
So 208 miles equals 5 gallons so if you add 208 two times you will already have used 10 gallons and that equals 416 miles so far. So now you have to divide 208 by 5 and that equals 41.6 so 416 plus 41.6 equals 457.6 miles

Answer:
The length of the building in the scale drawing is 31. 25 Inches
Step-by-step explanation:
Scale drawing was used0. 25 inches represents 2 feetThe length of the building is 250 feetThen,
If 0. 25 inches = 2 feet
Then x inches = 250 feet
cross multiply
x × 2 = 0. 25 × 2500
Multiply through, we then have
2x = 62. 5
Make 'x' the subject by dividing both sides by 2

Jason has already used 4/12 cans of paint while painting furniture. He is painting chairs which each use 10/6 cans of paint.
What is the total number cans used if he paints 19 chairs?
Your final answer should be a decimal.
Answers
Answer:
Based off of the calculations I did, I got 32 as the answer.
Step-by-step explanation:
Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.
So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.
10/6 * 19 = 31.666...
Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.
31.666... + 4/12 = 32.
Thus, Jason used 32 cans of paint in total.

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs. After selling 101010 tickets, they were still at a net loss of \$800$800dollar sign, 800 (due to the production costs). They sold each ticket for \$70$70dollar sign, 70.
Answers
Answer:
Price of each ticket = $70
The revenue generated from sales of 10 tickets = 70 x 10 = $700
After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500
Net Profit = Revenue - Cost
Revenue from n tickets will be = 70n
Cost = $1500
So, net profit as a function of number of tickets sold = P(n) = 70n - 1500
