To find the perimeter of a triangle, we need to add up the lengths of all three sides. In this case, the sides of the triangle are given by the expressions 3x2 - y2, 4x2 - 7xy + 4y, and -3x + 7xy + 8y2.

To find the perimeter, we can simply add up these three expressions:

Perimeter = 3x2 - y2 + 4x2 - 7xy + 4y - 3x + 7xy + 8y2

= 7x2 - 3xy + 12y

This is the perimeter of the triangle. Note that the perimeter is a scalar quantity, not a vector, so it does not have a direction associated with it.

Example of discontinuity in mathematical function is given by :

f(x) = ( x - 1 )/ ( x - 2) at x = 2.

Discontinuous function is defined as:

f(x) = ( x - 1 ) / ( x - 2 )

When x = 2 function does not defined .

Hence it is not continuous at x = 2.

Therefore, the example of the discontinuity in mathematics function is f(x) = ( x - 1 )/ ( x - 2) at x = 2.

The property of congruence illustrated in the statement is the transitive property.

The transitive property states that if A is congruent to B and B is congruent to C, then A is congruent to C. In other words, if two things are congruent to a third thing, they are also congruent to each other.

In the statement "If AB ≅ DE, EF ≅ DE then AB ≅ EF," AB is congruent to DE, and EF is congruent to DE, so AB must also be congruent to EF according to the transitive property.

The other properties you listed are not applicable in this case. The symmetric property states that if A is congruent to B, then B is congruent to A. The reflexive property states that every object is congruent to itself. And multiplication is not a property of congruence.

He would pay $160 after one year if the installation fee per month is $45.

The cost of installing something. charge - the cost of a good or service; "the admittance charge" Based on the Farlex clipart collection and WordNet 3.0. Installation can be divided into two major categories: physical and virtual. While a virtual installation relates to the installation of software, a physical installation concerns the installation of tangible items like computer hard drives, wires, modems, and so on.

Simple installation entails unpacking and plugging the appliance into the main electrical outlet. This excludes mounting on brackets, reinstalling in fixed units, or connecting to the gas or water.

Step-by-step explanation:

The time which has passed when Tom overtakes Hazel is after Hazel has walked 1 hr 15 minutes and in that time Hazel has walked

1.25 * 4.8

= 6 km.

So, Tom runs 6 km in 10:15 - 9.39 = 36 minutes

= 0.6 hrs.

So, Tom's speed is 6/0.6 = 10 km/hr.

,

and Tom will take 18/10 = 1.8 hours to finish the route,

= 1 hr 48 minutes

So he finishes the route at

The equation for capital gain as a percent of the original purchase price will be equal to a = (y - x)/x × 100.

If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.

The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. A mathematical operation like reduction, addition, multiplication, or division is used to include terms in an expression.

As per the given information in the question,

Use the equation for capital gain,

Let the selling price be y and the purchase price is x dollars.

Capital gain = Selling price - Purchase

Substitute the values,

Capital gain = y - x

Now, let's find out the percent increase.

Let's assume that 'a' is the percent increase.

So, the equation will be,

(a)(x) = y - x

ax = y - x

Divide both sides by x.

(ax)/x = (y - x)/x

a = (y - x)/x

Multiply the equation by 100 to show in percentage form,

a = (y - x)/x × 100

For the equation y=0, there is much less math involved. This is because, no matter what, for any value of x, y must always be equal to zero.

This is so because the y-intercept occurs at x = 0. X = 0, mx = 0, and Y = B at this point. When y = 0, we solve the equation for x to determine the x-intercept. The line crosses the x-axis at y=0,

You can mistakenly think of the line y = 0 as the y-axis, be aware of this. It's not right. Simply put, the line y=0 indicates that the y coordinate is always 0 for all locations (x, y) in the x-y plane, indicating that the line y=0 represents the x-axis.

The graph of the equation that is parallel to 4x – 3y = –12 is determined as: A. y = 4/3x - 3/2.

If two lines are parallel to each other, their graph will have the same slope value, m. This means if their equations are expressed as y = mx + b in slope-intercept form, they will both have the same value of m.

Given the equation of a graph as 4x - 3y = -12, rewrite it in slope-intercept form to determine the slope value:

4x - 3y = -12

-3y = -4x - 12

-3y/-3 = -4x/-3 - 12/-3

y = 4/3x + 4

This means the slope, m is 4/3. The slope of the graph that is parallel to it will also have a slope of 4/3.

The slope of y = 4/3x - 3/2 is also 4/3, therefore, the answer is: A. y = 4/3x - 3/2.

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis) respectively.

In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).
