Answer:

12-4r

Step-by-step explanation:

4r<12 because r<3 so you flip it.

The true statement about a and p is a is positive and p is positive.

We have the equation

y= ax+ p

where a and p are real numbers.

In general, "a" represents the slope of the line (the rate of change of y with respect to x).

and, "p" represents the y-intercept (the value of y when x = 0).

The specific values of a and p can be determined by examining the graph or given data points.

By looking the graph, the slope is positive

b is the y intercept, where x = 0 and that is positive.

Based on the information given in the advertisement, we can conclude that the sale price of the table is $420.

Here's how we can arrive at this answer:

Let the original price of the table be represented by P.

We know that the sale price of the table is obtained by reducing the original price by 30%. Mathematically, this can be represented as:

Sale price = P - 0.3P

Simplifying this expression, we get:

Sale price = 0.7P

We are also given that the sale saves us $180 on this table. Mathematically, this can be represented as:

0.7P - P = -$180

Simplifying this expression, we get:

-0.3P = -$180

Dividing both sides by -0.3, we get:

P = $600

Therefore, the original price of the table was $600.

Using the equation for sale price that we derived earlier, we can now find the sale price of the table:

Sale price = 0.7P = 0.7 x $600 = $420

Hence, the sale price of the table is $420.

The maximum value among 3, π, and √2 is π (approximately 3.14159).

To determine the maximum value among 3, π, and √2, we compare the numbers to find the largest one.

Comparing 3 and π:

Since π (approximately 3.14159) is greater than 3, we can eliminate 3 from consideration.

Comparing π and √2:

To compare these two numbers, we can square both of them. Squaring π yields approximately 9.8696, while squaring √2 gives us exactly 2. Since 9.8696 is greater than 2, we can eliminate √2 from consideration.

Thus, the maximum value among 3, π, and √2 is π (approximately 3.14159).

The average of the four odd whole numbers (12) is greater than the average of the four even whole numbers (11).

To determine which average is greater, let's calculate the average of the four even whole numbers from 8 to 15 and the average of the four odd whole numbers from 8 to 15.

The even numbers from 8 to 15 are 8, 10, 12, and 14.

To find their average, we sum them and divide by 4:

Average of even numbers = (8 + 10 + 12 + 14) / 4 = 44 / 4 = 11.

The odd numbers from 8 to 15 are 9, 11, 13, and 15.

Similarly, we find their average:

Average of odd numbers = (9 + 11 + 13 + 15) / 4 = 48 / 4 = 12.

Please find attached the graph of the straight line equation; y = -2·x + 3/2, which is the same as the graph of the equation; 4·x + 2·y = 3, created with MS Excel

An equation of a straight line is an equation of the form; y = m·x + c

b. 1. The equation of the line is; 4·x + 2·y = 3

The above equation of the line can be expressed in slope-intercept form; y = m·x + c, where; m is the slope of the graph of the equation and c is the y-coordinate of the y-intercept, by making y the subject as follows;

2·y = 3 - 4·x

y = (3 - 4·x)/2

y = 3/2 - 2·x

Therefore; y = -2·x + 3/2

The above equation indicates;

The slope, m = -2

The y-intercept, c = 3/2

The coordinate of the y-intercept is therefore; (0, 3/2)

The point (0, 3/2) is to be plotted on the graph

2. In order to draw the graph, the coordinates of a second point can be found as follows;

The slope of the graph = The ratio of the rise to the run of the graph

Slope = Rise/Run = Δy/Δx

The rise = The number of units a point progresses vertically

The run =  The number of units a point progresses horizontally

Therefore, a slope of -2, indicates;

Slope = Rise/run = Δy/Δx = -2 = -2/1

A rise of -2 units is accompanied by a run of 1 unit

In terms of x and y an increase of 1 unit in the x-value is accompanied in the y-value by a -2 units increase.

Therefore, a second point on the graph is; (0 + 1, ((3/2) - 2)) = (1, -1/2)

3. The line of the graph therefore passes through both (0, 3/2) and (1, -1/2)

Drawing a line through the above two points creates the graph of the equation, 4·x + 2·y = 3

In the coordinate plane, the vertices of triangle PAT are P(-1,-6), A(-4,5), and T(5,-2) forms an isosceles triangle.

To prove that triangle PAT is an isosceles triangle, we need to show that at least two sides of the triangle are congruent.

Let's calculate the distances between the vertices:

Distance between P and A:

PA = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(-4 - (-1))² + (5 - (-6))²]

= √[9 + 121]

= √130

Distance between P and T:

PT = √[(5 - (-1))² + (-2 - (-6))²]

= √[(5 + 1)² + (-2 + 6)²]

= √[36 + 16]

= √52

= 2√13

Distance between A and T:

AT = √[(5 - (-4))² + (-2 - 5)²]

= √[(5 + 4)² + (-2 - 5)²]

= √130

We can see that PA = AT = √130, and PT = 2√13.

Since PA = AT, we have shown that two sides of the triangle are congruent.

Therefore, triangle PAT is an isosceles triangle.

We have shown that the path of a moving point with velocities u + ey and v + ex, parallel to the axes of x and y, is either a line (when v - [tex]e^2[/tex] ≠ 0) or a horizontal line (when v - [tex]e^2[/tex] = 0), both of which are conic sections.

To show that the path of a moving point parallel to the axes of x and y with velocities u + ey and v + ex is a conic section, we can analyze the motion of the point using the principles of calculus and conic sections.

Let's denote the position of the point at any given time t as (x, y). We are given that the velocities along the x and y axes are u + ey and v + ex, respectively. This means that the derivatives of x and y with respect to time, dx/dt and dy/dt, can be expressed as:

dx/dt = u + ey

dy/dt = v + ex

Now, let's integrate these expressions to obtain x and y as functions of t. Integrating dx/dt with respect to t gives:

x = ut + eyt + C1

Similarly, integrating dy/dt with respect to t gives:

y = vt + ext + C2

Where C1 and C2 are constants of integration.

Now, we can eliminate the parameter t by expressing t in terms of x and y. From the equation y = vt + ext + C2, we can solve for t:

t = (y - ext - C2) / v

Substituting this value of t into the equation for x, we get:

x = u[(y - ext - C2) / v] + ey[(y - ext - C2) / v] + C1

Simplifying this equation, we obtain:

vx - u - evx + ue + vy - [tex]e^2[/tex]x - eyC2 = C1v

Rearranging the terms, we get:

vx - vy + ue + evx - [tex]e^2[/tex]x = C1v + eyC2 - u

Let's define new constants A = ue + ev and B = C1v + eyC2 - u. The equation then becomes:

(v - [tex]e^2[/tex])x + (u + ev)y = A + B

This equation is in the standard form of a conic section, specifically a line. However, we can manipulate this equation further to reveal other possible conic sections.

Let's consider the case when v - [tex]e^2[/tex] ≠ 0. In this case, we can divide both sides of the equation by v - [tex]e^2[/tex], yielding:

x + [(u + ev)/(v - [tex]e^2[/tex])]y = (A + B)/(v - [tex]e^2[/tex])

Now, let's define another constant C = (u + ev)/(v -[tex]e^2[/tex]) and rewrite the equation as:

x + Cy = D

Where D = (A + B)/(v - [tex]e^2[/tex]).

This equation represents a line in the x-y plane.

On the other hand, if v - [tex]e^2[/tex] = 0, the equation becomes:

0x + (u + ev)y = A + B

This simplifies to:

(u + ev)y = A + B

Which is a horizontal line parallel to the x-axis.

Therefore, we have shown that the path of a moving point with velocities u + ey and v + ex, parallel to the axes of x and y, is either a line (when v - [tex]e^2[/tex] ≠ 0) or a horizontal line (when v - [tex]e^2[/tex] = 0), both of which are conic sections.

The general solution to the differential equation -√3 cscθ = 2 is θ = 2π/3 + nπ.

To find the general solution to the trigonometric equation -√3 cscθ = 2, where n is an integer, we need to solve for θ.

Let's start by rewriting the equation:

-√3 cscθ = 2

Since cscθ is the reciprocal of sinθ, we can rewrite the equation as:

-√3 / sinθ = 2

To solve for θ, we can take the reciprocal of both sides:

sinθ / -√3 = 1/2

Next, we can take the reciprocal of both sides again:

-√3 / sinθ = 2

Now, we can find the values of θ that satisfy this equation. The general solution is given by:
