The ratio of x:y is 4:3.
What is ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categories ratios. Part to whole ratio is one, while part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
For instance, a class has a 12:15 boy-to-girl ratio, but the part-to-whole ratio refers to the relationship between a particular group and the entire. For instance, five out of every ten people enjoy reading. As a result, the ratio of the portion to the total is 5: 10, meaning that 5 out of every 10 persons enjoy reading.
Given:
15% of x=20% of y
So,
15 / 100 × x = 20 / 100 × y
3 / 20x = 1/5y
x / y = 1/5 x 20/3
x / y = 4/3
Hence, the ratio of x:y is 4:3.

What is the slope of the line that passes through the points (2, 8) and
(-3, 14)? Write your answer in simplest form.
Answer:
-6/5
Step-by-step explanation:
slope = (y_2 - y_1)/(x_2 - x_1)
slope = (14 - 8)/(-3 - 2)
slope = 6/(-5)
slope = -6/5
The solution is -6/5
The slope of the line that passes through the point A ( 2 , 8 ) and B ( -3 , 14 ) is slope m = -6/5
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the first point be A
Now , the value of A is A ( 2 , 8 )
Let the second point be B
The value of B is B ( -3 , 14 )
And , the slope of the line between 2 points is given by the formula,
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 14 - 8 ) / ( -3 - 2 )
On simplifying the equation , we get
Slope m = 6 / ( -5 )
Slope m = -6/5
Therefore , the slope of the line is m = -6/5
Hence , The slope of the line that passes through the point A ( 2 , 8 ) and B ( -3 , 14 ) is slope m = -6/5

4. The average speed is 65 miles/ h.
What is slope?
The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as,
The slope of line is the measure of steepness or the direction of line the coordinate plane.
m = Δy/Δx
where, m is the slope
1. The co- ordinates of the graph is (0, 0) and (-1, 2)
slope = (2-0) / (-1 - 0) = 2/ (-1) = -2
Thus, the slope is -2.
2. The co-ordinates of the graph is (0, 0) and (4, 4)
slope = (4 - 0) / (4- 0) = 4/4 = 1
Thus, the slope is 1.
3. cost of 7 yards fabric = $45. 43
cost of 1 yards fabric = 45. 43/7

What kind of transformation converts the graph of f(x)=3x+9 into the graph of g(x)=3x–10?
The transformation of the functions from f(x) to g(x) is translate 7 units right and 2 units up
How to determine the transformation?The equations of the functions are given as
f(x) = 3x + 9
g(x) = 3x - 10
Let the translations from f(x) to g(x) be h and k
So, we have
g(x) = f(x + h) + k
This gives
f(x + h) = 3(x + h) + 9 + k
Open the brackets
f(x + h) = 3x + 3h + 9 + k
Substitute f(x + h) = 3x + 3h + 9 + k in g(x) = f(x + h) + k
g(x) = 3x + 3h + 9 + k
This means that
3x + 3h + 9 + k = 3x - 10
Evaluate the like terms
3h + 9 + k = - 10
This gives
3h + k = - 19
Express -19 as -21 + 2
3h + k = -21 + 2
Express 21 as 3 * 7
3h + k = -3 * 7 + 2
By comparison, we have
h = -7 and k = 2
This means that the transformation is 7 units right and 2 units up

The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Use the constraints of the real-world situation to predict the height of the water balloon at 15 seconds. Use complete sentences to support your answer.
The representation of the linear model shows that the height of the balloon after 15 seconds is 0 feet.
In statistics, the term "linear model" has several meanings depending on the situation.
Since it refers to regression models the most, the phrase is frequently used synonymously with a linear regression model. When used in time series analysis, the phrase has a different meaning. In each case, "linear" refers to a subclass of models for which it is possible to significantly reduce the complexity of the underlying statistical theory.The water balloon is hurled from a height of 40 feet above, as can be seen from the linear model.
The balloon now ascends to a height of 70 feet before returning to ground due to gravity.
The balloon drops to the earth and makes a splash after about ten seconds.
Therefore, the balloon will remain at the ground for some more time.
As a result, according to the linear model, the balloon's height at time 15 seconds is always 0 feet.

The equation of the line passing through P(0, 0) perpendicular to y = -9x - 1 will be [tex]y = \frac{1}{9}x[/tex]
The given question states that the line passes through the point P(0, 0) perpendicular to the line y = -9x - 1. We have to find out the equation of the line. We have to find the equation in slope-intercept form.
We know the slope intercept is: y = mx + b
Also, given the perpendicular line has slope m₂ = -9 according to slope-intercept form. And we know that perpendicular lines have a slope that is equal to the negative reciprocal.
So, the Slope of the line m₁ = Negative reciprocal of the slope of the perpendicular line.
=> [tex]m_{1} = -\frac{1}{m_{2} }[/tex]
=> [tex]m_{1} = -\frac{1}{(-9)}[/tex]
=> [tex]m_{1} = \frac{1}{9 }[/tex]
We get the slope [tex]m_{1} = \frac{1}{9 }[/tex]. Also, it is given that the line passes through (0, 0) so the y-intercept b = 0. Putting these values in slope-intercept form, we get:
=> y = mx + b
