An isosceles triangle has a perimeter of 23 meters. The base of the triangle is 7 meters.
Write an equation to represent the other lengths, X, of the triangle.
An equation to represent the other lengths, X, of the triangle is 2X+7=23.
What is meant by an isosceles triangle?An isosceles triangle is one that has two equal-length sides in geometry. The term "equilateral triangle" can refer to a shape with either exactly two sides that are the same length or at least two sides that are the same length, with the latter definition containing the equilateral triangle as an exception. The faces of bipyramids and a few Catalan solids are examples of isosceles triangles, as are the isosceles right triangle, the golden triangle, and others.
Isosceles triangles have been the subject of mathematical research since the time of the Babylonians and the Egyptians.
Given,
Perimeter of an isosceles triangle=23 meters
The base of a triangle=7 meters
P=2X+b
2X+7=23
Therefore, an equation to represent the other lengths, X, of the triangle is 2X+7=23.

What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The synthetic division problem is,
⇒ - 3/ 2 4 -4 6
Now,
Since, The synthetic division problem is,
⇒ - 3/ 2 4 -4 6
Hence, The divisor of the synthetic division problem is,
⇒ x - (- 3) = x + 3
And, There are four leading coefficient.
Hence, The dividend of the polynomial must be degree of 3.
So, By the leading coefficient are;
⇒ 2, 4, - 4, 6
Hence, We get;
⇒ 2x³ + 4x² - 4x + 6
Thus, The value of divisor and the dividend for the synthetic division problem will be;

Find g(x), where g(x) is the reflection across the x-axis of f(x)=3x–9
The graph of f(x) = x in a straight line passing through the origin (0,0) and at an angle of 45 degrees to the x axis. It increases from left to right.
What is graph?
In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to linked and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other forms of graphs.
A simple graph is one in which no two vertices are connected by more than one edge, and no edge begins or finishes at the same vertex. In other terms, a simple graph is one that doesn't have loops or many edges.
Reflection in the x axis will convert all positive values of f(x) to negative values of f(x) and vice versa.
g(x) = - x and is a straight line passing through origin at angle of 45 degrees but the slope descends from left to right.

The points V (1, 1), W (3,-2), X (8, 1), and Y (4, 5) form quadrilateral VWXY.
Having sides that are parallel to one another, a parallelogram is a two-dimensional geometric shape. It is a sort of four-sided polygon (sometimes known as a quadrilateral) where each parallel pair of sides is the same length.
What is the parallelogram?With two sets of parallel sides, a parallelogram is a quadrilateral. A parallelogram has equal-length opposing sides and equal-size opposing angles. Also supplementary to the transversal are the interior angles on the same side. A 360 degree circle is formed by adding together all inside angles.Parallelepiped is the name given to a three-dimensional shape with parallelogram-shaped faces. The base, which is one of the parallel sides, and height, which is the distance from top to bottom, both affect the parallelogram's size. The lengths of the four sides determine a parallelogram's perimeter.Parallelogram-like characteristics can also be found in the shapes of a square and a rectangle.AB || CD and AD || BC form a parallelogram in the preceding illustration, which shows that ABCD.In addition, AB = CD and AD = BC.
A = C & B = D are also true.
Because these inner angles are on the same side of the transversal, A and D are additional angles as well. The extra angles B and C work in the same way.Therefore,
∠A + ∠D = 180
∠B + ∠C = 180

Answer:
You're welcome. :)
Step-by-step explanation:
Hope you're able to understand it.
a. x and y-intercepts.
b. symmetries (if any) about the x-axis, the y-axis, and the origin.
When (a, b) appears on a graph, it is said to be symmetric around the x-axis if (a ,b) also appears there at the same time. A graph that is symmetric around the x-axis is shown in the following illustration. A graph is said to be symmetric around the y-axis if and only if (a ,b) and (a, b) are both present on it.
We replace all the x's with -x and check to see if we get an equivalent formula to determine algebraically whether a graph is symmetric with regard to the y axis. Example: A) To make y = x2 symmetric with regard to the y axis, we substitute y = (-x)2 = x2 for y = x2.
Ordered pairs (x, y) and and exist in equations or functions that are symmetric to the origin (-x, y). The original equation is symmetric with respect to the origin if you swap -x for x and -y for y in the equation and simplify.
If we reflect a function's graph about the y-axis, we will get the same graph since some functions might be symmetrical about the y-axis. We may reflect various functions about the x- and y-axis and obtain the same graph. These two symmetry kinds are known as even and odd functions.

What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = (f(x + h) - f(x)) /(x + h - x).
Its geometrical aspect is the slope of the tangent at a given point.
The given equation is y = 2x² + 4x - 6.
The vertex is a point at the graph where the slope becomes zero. It can be found by equating the differentiation of the equation to zero as below,
y = 2x² + 4x - 6
=> y' = 4x + 4 = 0
=> x = -1
At x = -1 the value of y can be found as,
y = 2 × -1² + 4 × -1 - 6
= 2 - 4 - 6
= -8
Thus, the vertex is given as (-1, -8) which is only valid for option (b).
Hence, the key points to be used by sandy to draw the graph are x-intercept (1, 0), y-intercept (-3, 0) and vertex (-1, -8).

They took 1.53 hrs long before they are 1000 nautical miles apart.
What is the distance?
Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.
Here, we have
A plane leaves Charlotte at 9:00 AM and flies north at 400 knots. At the same time, another plane flies south from Charlotte at 250 knots
The speeds are added when going in opposite directions = 400 + 250knots = 650 knots
We apply here distance formula,
Distance = rate × time
t = d/r

The Marching Band is traveling from Minnesota to Florida to perform in a national competition. A train ticket from Minnesota to Florida costs $150 and takes 15 hours of travel time per student. To rent a bus to make the trip, it costs $120 per student and takes 20 hours of travel time per student. The band has $4,800 to spend on the trip and can only spend 720 hours of total travel time. Use the information below.
Let x = Students traveling by train
Let y = Students traveling by bus
Therefore,
$150x + $120y < $4,800 and
15x + 20y < 720.
The graph of these functions is to the right.
It is impossible for a negative number of students to go on the trip, so x and y both have to be greater than zero. Therefore, the functions are confined to the first quadrant.
Number of students function:

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Let x = Students traveling by train
Let y = Students traveling by bus
Now equations to represent the situation is
150x+120y=4,800 and 15x+20y=720
30(5x+4y)=4,800
5x+4y=160 ----------(I)
15x+20y=720
3x+4y=144 ----------(II)
Subtract equation (II) from (I), we get
5x+4y-(3x+4y)=160-144
⇒ 2x=16
⇒ x=8
Substitute x=8 in equation (I), we get
