In slope intercept form, Equation 14x-20y=-13 can be written as 13 + 4y/20 = y.

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation. The slope, m, is a measure of how steep a line is. The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

Given,

Equation

14x-20y=-13

In slope intercept form

13 + 4x = 20y

13 + 4y/20 = y

The standard form of linear equation in two variables is Ax + By = C.

The standard form of linear equation in two variables is Ax + By = C, where A, B and C are constants and A and B are not both zero. This equation can be used to represent a line on a graph, which can be found by plotting any two points that satisfy the equation.

To calculate the equation of a line in standard form, first identify two points on the line. For example, point (x1, y1) and point (x2, y2). Then, calculate the slope of the line using the formula m = (y2 - y1) / (x2 - x1). The slope determines the constants A and B for the equation. A = m and B = -1. Finally, calculate the constant C by substituting one of the two points into the equation. C = Ax1 + By1.

An asymptote of a function is a line that the graph of the function gets closer and closer to, but never touches. It is an approaching line that has a fixed slope. Asymptotes are used to determine the behavior of a function as it approaches infinity or negative infinity. They can be used to help visualize the behavior of the function in the large and small limits. Asymptotes can be either horizontal or vertical. A horizontal asymptote is a line that the graph of the function approaches as it approaches positive or negative infinity, and a vertical asymptote is a line that the graph of the function approaches as it approaches either the positive or negative x-axis. Asymptotes can also be used to describe the behavior of a function near a local minimum or maximum. Asymptotes can be found by looking at the degree and leading coefficient of a polynomial, or by analyzing the behavior of the function at different points.

The point lies in the solution set if x represents the number of children's books and y represents the number of puzzle books Amelie buys (9,5).

To find the point that lies in the solution set, you need to consider the constraints given in the problem. Amelie wants to purchase at least 2 more children's books than puzzle books, which means that the number of children's books should be greater than or equal to the number of puzzle books plus 2. She can afford no more than 15 items total, which means that the total number of children's books and puzzle books should be less than or equal to 15.

Based on these constraints, the point that lies in the solution set is (9,5). This point satisfies both constraints, because the number of children's books (9) is greater than the number of puzzle books (5) plus 2, and the total number of children's books and puzzle books (14) is less than or equal to 15. Therefore, the correct answer is (d) (9,5).

The end behavior of the graph would be that it would approach negative infinity as x approaches positive infinity, and negative infinity as x approaches negative infinity.

When the degree of a polynomial is even and the leading coefficient is negative, the end behavior of the graph is that it will approach negative infinity as x increases or decreases without bound in either direction. This is because the degree of the polynomial is even and the coefficient is negative, meaning that the leading term will always be negative. Since the leading term is always negative, the graph will approach negative infinity as x increases or decreases without bound in either direction. This is the general behavior of a polynomial with even degree and a negative leading coefficient.

The area of segment enclosed by chord [BC] is 0.94 [tex]cm^{2}[/tex]

Segment and area of a circle segment:

A segment is essentially the area of a circle between the chord and the arc. A circle is a path that a point equidistant from a single point on the plane can follow; this point is known as the circle's center, and the distance between it and that point is known as the circle's radius. A segment is a section of a circle's interior. A sector is the region that a segment encloses and the angle that a segment occupies. By deducting the triangle formed inside the sector from the sector where the segment is located, one can calculate the area of a circular segment.

Given radius and angle subtended by arc on circle is 4 cm and 55° respectively.

So the length of chord [BC] is [tex]\frac{55}{180}[/tex]×π = 3.84 cm.

Required area of segment enclosed = Area of segment subtended by arc [BC] - area of ΔABC

>semi-perimeter of ΔABC is [tex]\frac{(4+4+3.84)}{2} = 5.92[/tex]

>Area of ΔABC is [tex]\sqrt{5.92*(5.92-4)*(5.92-4)*(5.92-3.84)} = 6.74 cm^{2}[/tex]

>Area of segment subtended by arc {BC} = θ/360° × π[tex]r^{2}[/tex]

                                                                     =[tex]\frac{55}{180}[/tex]×16π

                                                                     = 7.68[tex]cm^{2}[/tex]

∴The area of segment enclosed by chord [BC] is [tex]7.68-6.74 = 0.94 cm^{2}[/tex]
