1. The two points that lie on a line with a slope of 2/3 are: D. (–3, 2) and (0, 4)
2. The slope is: B. 0.
How to Find the Slope of a Line?The formula for finding the slope of a line is:
Slope (m) = change in y/change in x
1. To find the two points that has a slope of 2/3, calculate the slope of each of them:
Slope for A = (0 - 0)/(3 - 2) = 0
Slope for B = (-4 - 2)/(3 - 1) = -3
Slope for C = (3 - 0)/(2 - 0) = 3/2
Slope for D = (4 - 2)/(0 -(-3)) = 2/3
Therefore, the two points that lie on a line with a slope of 2/3 are: D. (–3, 2) and (0, 4)
2. Slope of the line = change in y / change in x = (-1 -(-1))/(-3 - 6)
Slope (m) = 0/-9
Slope (m) = 0
The slope is: B. 0.

Kenny says that to find how fast Spotify is downloading songs, you can always take the number of songs left to download and divide by how long the playlist has been downloading. Do you agree or disagree? Explain.
I do not agree. To find how fast Spotify is downloading songs, divide the number of songs already downloaded by how long the playlist has been downloading.
What is division?Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.
For example, assume that you are downloading a playlist that has 100 songs. 80 songs have been downloaded in the past two hours. In order to determine the rate at which songs are downloaded, divide 80 by 2.
Speed = 80 / 2 = 40 songs per hour

A new car is priced at £7500.
In a sale it is reduced by 20%.
Calculate the reduction in price.
Answer:£1500
7500 divided by 10=750. £750 is 10% so 750x2 which is 1500, is 20%. Therefore, it is reduced by £1500
Answer:
£1500
Step-by-step explanation:
20% = 20/100 = 0.2
7500 - (7500*0.2)
= 7500 - 1500
= 6000
The reduction in price is:

The graph of g(x) is wider than f(x) and is shifted to the right 3 units and down 3 units.
Answer: The graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 units.
Step-by-step explanation: I took the quiz and got it right
The function f(x) = x² is transformed and became g(x) = 3(x+2)² -1 has the graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 unit.
What are graph transformations ?By applying suitable graph transformation we can shift, stretch, shrink, a given graph along x and y axis.
According to the given question given a graph f(x) = x² and g(x) is 3(x+3)² - 3.
Let us break transformations of g(x) one by one.
g(x) = 3f(x) which implies it's amplitude or vertical stretch is increased by a factor of 3.
Now, g(x) = 3(x+3)² implies the graph is shifted towards left by 3 units as x + 3 = 0 is x = -3.
Now, g(x) = 3(x+3)² - 3 implies that the whole graph has been shifted 3 units down along the y axis.
Hence the graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 units.

The width and the length of the rectangle are equal to 6√5 units and 3√5 units, respectively.
What are the dimensions of the rectangle?
In this problem we find the area of the rectangle and the ratio of the length to the width of the figure. Mathematically speaking, the area of the rectangle is described by the following formula:
A = (2 · x) · x
A = 2 · x²
If the area of the rectangle is equal to 90 square units, then the width of the rectangle is:
2 · x² = 90
x² = 45
x² = 3² × 5
x = 3√5
The width of the rectangle is equal to 3√5 units. By the given ratio, the length of the rectangle is equal to 6√5 units.
Therefore, the length and width of the rectangle are equal to 6√5 units and 3√5 units, respectively.

What is a perimeter?The total length of a shape's boundary is referred to in geometry as the perimeter of the shape. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.
A regular polygon's perimeter is equal to the product of all of its sides, which is equal to the number of sides times the length of a side.
We use the general method to get the perimeter of an irregular shape since the sides of an irregular polygon might not all be the same length.
Therefore, the irregular polygon's perimeter equals the total of its sides.

The specific volume is 0.0135 ft^3
The density is 74.07 lb/ft^3
Here,
A 2-lb sample of an unknown liquid occupies a volume of 47.6 in^3.
We have to find the specific volume and density.
What is Specific volume?
Volume is a measure of the amount of space occupied by an object.
Now,
Mass = 2 lb
Volume = 47.6 in^3
= 0.027 ft^3
Hence, Specific volume = volume/ mass = 0.027/2 = 0.0135 ft^3
And, Density = mass/ volume = 2/ 0.027 = 74.07 lb/ft^3
So, The specific volume is 0.0135 ft^3
The density is 74.07 lb/ft^3
