Answer:
y = - 3x + 24
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
- 3x - y = - 24 Equation
Step 3:
- 3x = y - 24 Add y on both sides
Step 4:

Pick from 1. 2. And 3.
Answer:
#2 is not a function
Step-by-step explanation:
Although there can be multiple y-values attributed to a single x-value, there can only be ONE x-value(of a number) in a function, so #2 would be incorrect seeing as it uses the x-value, 2, two times.
A mile is equal to approx
1.609 kilometers. How many kilometers is 2.5 miles!
Justify your answers
Answer:
Varied answer. Either 4.0225 km or 4.025 km
Step-by-step explanation:
Process 1: round 1.609 to 1.61, then multiply 1.61 by 2.5. This will give you 4.025 km. You might even go a step further and round it to 4.03 to put it in simplest form
Process 2: Leave 1.609 as is, multiply it by 2.5, giving you 4.0225 as an answer.
It all depends on how your teacher wants you to round to solve the equation.

A track team with 12 members decided to buy T-shirts that cost $8.95 each. What was the cost of the 12 T-shirts?
Answer:
Step-by-step explanation:
the cost of the t-shirts was $107.4
Answer: $107.4
Answer: $107.40
Step-by-step explanation:
If you have 12 members that want to buy 1 shirt each then the they would be buying 12 shirts, that mean 12 of the $8.95 shirts.
$8.95 times 12 is $107.40
An easy way you can do that is by putting $8.95 times 10 which if something is times’d by 10 you just as a 0 to the end, ( if it’s a decimal you move the decimal back one) so then it’s $89.5, so now you’ve added 10, but you need to add 12, so you add 2 more $8.95 so $17.90 then add that to $89.5 which equals $107.40

John has a garden with dimensions 7 feet long x 6 feet wide. He wants to enlarge the garden to an area of 108 square feet. How much farther will he need to extend the length of the garden to attain his desired area?
Answer:
11 feet
Step-by-step explanation:
It is found if originally the length was 7 ft, then it has to be 11 ft longer.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We have given the initial dimensions are:
length: 7 feet
width: 6 feet
Therefore the area of the garden is given by:
Area = L x W
Area = 7 feet x 6 feet = 42 square feet.
Since we need the area to be 108 square feet , then we can only change the length the width will still be 6ft.
We substitute the value of the new area and the width to the equation for the area as;
Area = L x W
108 = L x 6
L = 108/6
L = 18 feet
The length of the garden for the area to be 108 square feet, must be 18 ft.
This means that if originally the length was 7 ft, now it has to be 11 ft longer.

A circle is the set of all points in a plane that are equidistant from a common point.
Which statements are true about the description? Select three options.
The description is sufficient to describe all cases of a circle.
The description includes only necessary information to describe a circle.
The description is a mathematically precise definition of a circle.
The description does not rely on undefined terms.
The description contains every property of a circle
Answer:
i. The description is sufficient to describe all cases of a circle.
ii. The description includes only necessary information to describe a circle.
iii. The description is a mathematically precise definition of a circle.
Step-by-step explanation:
A circle can be described as a plane shape bounded by circumference. It's circumference can be determined by: 2[tex]\pi[/tex]r, where r is its radius.
Thus, it can be said that it contains equidistant (equal distant) points from a common central point called the center of the circle. This definition can be used to describe any circle.
Some of its parts are: diameter, radius, sector, semicircle etc.

slope is 4/7, and (1, 3) is on the line.
Answer:
4/7x - y = -17/7
Step-by-step explanation:
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
m = 4/7
Random point (1, 3)
Step 2: Find slope-intercept form
y = 4/7x + b
3 = 4/7(1) + b
3 = 4/7 + b
b = 17/7
y = 4/7x + 17/7
Step 3: Find Standard Form
-4/7x + y = 17/7
-(4/7x - y) = 17/7
4/7x - y = -17/7
The half-life of cesium-137 is 30 years. Suppose we have a 170-mg sample. What is the rate of decay after 150 years? (Round your answer to three decimal places.)
Answer:
5.313mg
Step-by-step explanation:
The half-life of cesium-137 is 30 years. Suppose we have a 170-mg sample. What is the rate of decay after 150 years? (Round your answer to three decimal places.)
Half life formula
= N(t) = No(1/2)^t/t½
N(t) = Amount after t years
No = Initial amount
t = time
t½ = half life
N(t) = 170 (1/2) ^150/30
N(t) = 170 × (1/2)^5
N(t) = 5.3125mg
Approximately the quantity left after t years = 5.313mg
A restaurant built a ramp to make their facility more accessible to people in wheelchairs. They covered the entire surface of the ramp with metal to make it more durable. How much metal did they use to cover the ramp, including the bottom? Give an exact answer (do not round).
Answer:
3.41 m² of metal would be needed to cover the ramp
Step-by-step explanation:
The ramp has the shape of a triangular prism.
A triangular prism is a prism that has two equal triangles as base connected by three lateral faces.
The surface area of a triangular prism is the sum of the area of its base and lateral faces.
The surface area = 2B + PH
Where B is the area of the base , H is the height of the prism and P is the perimeter of the triangular base
Hence:
B = 0.5 * 1 m * 0.8 m = 0.4 m²
h = 1 m
P = 1 m + 0.8 m + 0.81 m = 2.61 m
Surface area = 2 * 0.4 m² + 2.61 m × 1 m = 3.41 m²
3.41 m² of metal would be needed to cover the ramp

A hotel has 30 floors with 40 rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side face a golf course. There is an extra charge for the rooms with a water view. The hotel manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property. The manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view. What type of sample was obtained
Answer: Stratified Random Sample
Step-by-step explanation: The type of sampling exemplified by the manager's selection is Stratified Random Sampling whereby the entire population (guests in the hotel) are divided into subpopulation(independent subgroups) called strata; those with rooms facing the golf course and those facing the water view. The sample this have two strata based on the view in which the rooms are facing. Taking a simple random samples from each sub group of the entire population may lead to less bias since the customers may experience different level of satisfaction based on this condition.
The type of sample was obtained when manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view is Cluster sampling.
What is sampling?
Sampling is a process used in statistical analysis in which a predetermined number of observations are taken from a larger population.
Now here, the manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property.
So, here cluster sampling would be preferred because there are 30 floors and they can be classified as clusters and surveyed per floor.
Thus, the type of sample was obtained when manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view is Cluster sampling.

If the price of organic beef steak, regular beef steak, and pork chops each increased by 10%. Which of the products would you think was the most elastic. In other words, which has the most change to the quantity demanded because of the increase in price?
Answer:
organic beef steak
Step-by-step explanation:
Out of the three options provided, the one that would suffer the biggest change in elasticity would be the organic beef steak. This is because out of the three, the organic beef steak is normally the most expensive product. Adding an extra 10% to the regular price would make it that much more expensive and turn many people away from this product. Therefore, causing its demand to drop drastically as price increases. Since the other products are not as expensive/high-end demand may drop a little but not by much.
