length to breadth = 3/2.

so, when the breadth is 24, what is the factor compared to the original 2 of 3/2 ? 12.

2 × 12 = 24 cm

and then, we need to multiply the other ratio part by the sand factor

3 × 12 = 36 cm

when the length = 60 cm, then the factor compared to the original 3 of 3/2 is 20.

3 × 20 = 60 cm

and multiplying the other ratio part by the same factor

2 × 20 = 40 cm

when the breadth is 52, the factor compared to the original 2 of 3/2 is 26.

2 × 26 = 52 cm

and multiplying the other ratio part by the same factor

3 × 26 = 78 cm

The set of all possible y-x values is between 3 and 6, excluding both endpoints.

===================================================

Explanation:

The y-x value is smallest when:

I recommend to draw out a number line. The idea is to place x and y as close as possible to each other.

Based on those two conditions, we use y = 10 and x = 7 respectively. That gives y-x = 10-7 = 3 as the smallest possible difference. Keep in mind we can't actually reach this value so we would write y-x > 3 which is the same as 3 < y-x.

--------------------

Similarly, y-x is largest when:

Like earlier, use a number line to see why this would be the case. We're trying to space x and y out as far as possible.

The largest y value and smallest x value are y = 12 and x = 6 in that order. So the upper bound is y-x = 12-6 = 6. Like before, we can't actually reach this number which means we write y-x < 6.

--------------------

Recap:

Put those two results together in a tidy compound inequality to get the final answer    3 < y-x < 6

It says: The expression y-x is between 3 and 6, excluding both endpoints.

Answer:

y = 3x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 2, - 2) ← 2 points on the line

m = [tex]\frac{-2-4}{-2-0}[/tex] = [tex]\frac{-6}{-2}[/tex] = 3

the line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = 3x + 4 ← equation of line

Answer:

y=3x+4

Step-by-step explanation:

The formula used is point slope, or y=mx+b

here, the m is the slope, and the b is the y-intercept

The y-intercept is where the graph crosses the y-axis, also known as when x=0

In this case, the y intercept is at the point (0,4) so you'd plug in 4 for the 'b' in the equation

To find the slope, use the rise over the run of the graph.

To do this, pick two points along the graph, and count how many units up/down, and to the left/right between the two points

The units up/down goes on top, being positive if they're up, and negative if they're down

The units left/right go on bottom, being positive if they're right, and negative if they're left

In this case you go 3 units up, and 1 unit right, so the slope would be 3/1 or 3

What the slope and the y-intercepts represent are;

Slope means that the rate at which the number of miles people in the U.S. traveled per year increased was 0.048

y-intercept means that the number of vehicle-miles traveled in 1975 is; 1.345 (in trillions)

A reasonable prediction for the number of miles people in the U.S. will travel in 2022 is; 3.601 (in trillions)

The equation for the line of best fit is given as;

y = 0.048x + 1.345

where;

x is the number of years since 1975

y is the number of vehicle-miles traveled in trillions

The equation of a line in slope intercept form has the general form as;

y = mx + c

where;

m is slope

c is y-intercept

Thus;

Slope = 0.048 which is the rate at which the number of miles people in the U.S. traveled per year increases.

y-intercept = 1.345 (in trillions) which is the number of vehicle-miles traveled in 1975

The year 2022 will be 47 years since 1975 and so the prediction is;

y = 0.048(47) + 1.345

y = 3.601 (in trillions)

iven, the equation is (x - 1)² + 2(x + 1) = 0. We have to determine if the equation has a real root. By using algebraic identity, (a - b)² = a² - 2ab + b² (x - 1)² = x² - 2x + 1.

If it takes a printer seconds to print a single lyer, and it took 75 seconds to print a batch of lyers without stopping, the number of lyers in the batch is 75 / . This is because if it takes seconds to print a lyer, and we have 75 seconds available to print lyers, we can divide the total time available by the time it takes to print each lyer to find out how many lyers we can print.

For example, if it takes 3 seconds to print a single lyer, the number of lyers in the batch is 75 / 3 = 25. If it takes 2 seconds to print a single lyer, the number of lyers in the batch is 75 / 2 = 37.5.

Therefore, the number of lyers in the batch depends on the time it takes to print a single lyer. To find the exact number of lyers in the batch, we need to know the time it takes to print a single lyer.

A mathematical function called a probability distribution explains the likelihood of many alternative values for a variable. Graphs or probability tables are frequently used to represent probability distributions. The probability distribution of X is defined as the function f(x) p(x)= P(X=x) for any x falling within the range of X. The probability mass function for the discrete random variable X is another name for it.

A unique type of normal distribution with a mean of 0 and a standard deviation of 1 is known as the standard normal distribution, or z-distribution. By transforming the values of any normal distribution into z scores, it is possible to standardize it. Z scores provide the number of standard deviations from the mean that each value falls within.

The vertex form of a quadratic equation is a standard form of a quadratic equation that is written in the form:

y = a(x-h)^2 + k

where a, h, and k are constants. This form is called the vertex form because it represents the graph of the quadratic equation as a parabola, with the vertex of the parabola located at the point (h,k).

The vertex form of a quadratic equation is useful because it allows us to easily identify the vertex of the parabola and the direction in which the parabola opens. If a is positive, the parabola opens upwards and the vertex is the minimum point of the parabola. If a is negative, the parabola opens downwards and the vertex is the maximum point of the parabola.

Overall, the vertex form of a quadratic equation is a standard form that represents the graph of a quadratic equation as a parabola with a specific vertex location. It is useful for identifying the characteristics of the graph and for solving problems involving quadratic equations.
