The graph of the function C = 49 + 20m is a discrete function and is represented by vertical lines for whole numbered values of 'm'.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, That no. of months is a whole month and hence it is discrete as it can not take decimal values.

Step-by-step explanation:

When it comes to a business net worth is simple:

           assets - liabilities = net worth.

Assets are an expenditure that has utility through multiple future accounting periods.  For example, a company pays its electrical bill. This expenditure covers something (electricity) that only had utility during the billing period; therefore, it is recorded as an expense.

Conversely, the company buys a machine, that it expects to use for the next five years. Since this expenditure has utility through multiple future periods, it is recorded as an asset.

Cash, savings, inventory, investments, equipment, and receivables are also assets. Basically, anything that is owned and could be liquidated for cash.

In simple terms a liability is something that is owed to someone else:

What is a triangle Inequality Theorem?

In Euclidean geometry, the theorem is that the sum of any two sides of a triangle is greater than or equal to the third side; in symbols, a + b ≥ c. In essence, the theorem states that the shortest distance between two points is a straight line.

The Triangle Inequality theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

So, a difference of two sides <x< sum of two sides, will give you the possible length of a triangle.

Therefore, 24 − 11 < x < 24 + 11

13 < x < 35 is the possible length of the third side of a triangle.

13 < x < 35 satisfies the triangle inequality theorem.

Hence, all the possible lengths for the third side lie between 13 to 35 feet.

The slope of the ramp is the ratio of the y and x coordinates thus it will be 24 feet.

A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The situation is making a right-angle triangle as shown below.

The slope of the wheelchair = 2 feet / x

2/x = 1/12

x = 2 x 12 = 24 feet

Hence "The ramp will be 24 feet long since the slope is determined by the ratio of the y and x variables".

Answer:

to solve a system of linear equations by elimination, we need to eliminate one of the variables, for example, we could add the two equations together to eliminate the variable y. However, we need to make sure that the coefficients of the two equations are the same before we can add them together. We can do this by multiplying the first equation by -1.5 and the second equation by 1.5. This gives us the following system of equations:

-2.25x - 13.5y = -31.5

2.25x - 4.5y = 13.5

We can now add these two equations together to eliminate the variable y, which gives us the following equation:

0 = -18

This equation is not possible, so the system of equations does not have a solution.

On the blueprint what is the length of a room is 5square inch.

What is square?

A square is a quadrilateral because it has four equally sized sides. Our immediate surroundings is filled with many square-shaped things. Equal sides and interior angles of 90 degrees help you identify each square form. A closed form known as a square has four equal sides and two interior angles that are both 90 degrees. A square has a wide range of characteristics.

Given the square bedroom have 3 feet side

The area of the bedroom is = 3² = 9 sq inch

1 inch = 2 feet

1 square inch = 4 square feet

20 square feet = 5square inch

y=5x-23

Step-by-step explanation:

y=mx+b is the slope intercept form

m is slope

And b is y intercept

We know the line will have a slope of 5 since they are parallel both lines will have the same slope

y=5x+b

To find b we put in the given coordinates (4,-3)

-3=5(4)+b

-3=20+b

-20 -20

If Group 1 trees produce 25 percent more coconuts than Group 2, proportionately, Group 2 trees produce 120 coconuts.

Proportion refers to the two ratios equated to each other.

Proportion shows how much quantity or value is contained in another.

We depict proportions using fractional values, such as fractions, decimals, and percentages.

The number of coconuts produced by Group 1 trees = 150

The percentage by which Group 1 trees produce more than Group 2 = 25%

Let Group 1's production compared to Group 2's = 1.25 (100% + 25%)

Let Group 2's production = 100% = 150/125 x 100

= 120 coconuts

Thus, Group 2 trees would produce 120 coconuts compared to Group 1 trees that produced 150, which was proportionately, 25% more.

To solve this problem, we need to first perform the multiplication. In mathematics, multiplication is performed before division, so we should calculate the product of 6/7 and 1/2 before dividing it by any other number. To find the product, we simply multiply the numerators together to get 6 and the denominators together to get 14. So the product of 6/7 and 1/2 is 6/14.

The new coordinates are X'(8, 7), Y'(5, -2), Z'(7, 0).

The coordinates of the triangle are given as

X(-7, 8), Y(2, 5), Z(0,7).

The rotation is given as r(90,0) XYZ

This means that

We have (x, y) ⇒ (y, -x)

Substitute X(-7, 8), Y(2, 5), Z(0,7) in (x, y) ⇒ (y, -x)

So, we have

X'(8, 7), Y'(5, -2), Z'(7, 0).

Hence, the coordinates of the image are X'(8, 7), Y'(5, -2), Z'(7, 0).

The measure of the length EF of the triangle is; 21

We are given the the triangle BCD and we are told that;

E is the midpoint of BD.

F is the midpoint of CD

Now, since we have those midpoints, it means that by the concept of similar triangles, that;

DF/DC = EF/BC

Since F is the midpoint of DC, then it means that;

2DF = DC

We are given;

EF = 43 - 4x, and BC = 32 - 2x

Thus, we now have;

DF/(2DF) = (43 - 4x)/(32 - 2x)

1/2 = (43 - 4x)/(32 - 2x)

Cross multiply to get;

32 - 2x = 43 - 4x

4x - 2x = 43 - 32

2x = 11

x = 11/2

x = 5.5

Thus;

EF = 43 - 4(5.5)

EF = 43 - 22

EF = 21

Thus, we conclude that the side length EF is 21.

To find the side x, we can use the Law of Cosines, which states that in any triangle, the square of the length of any side is equal to the sum of the squares of the lengths of the other two sides minus twice the product of those two sides and the cosine of the angle between them. In symbols, if a, b, and c are the lengths of the sides of a triangle, and C is the measure of the angle opposite the side of length c, then we have the equation:

c^2 = a^2 + b^2 - 2ab * cos(C)

In our case, we are given the lengths of two sides (a = 10 and b = 6) and the measure of the angle opposite the unknown side (C = 0 degrees), so we can plug those values into the equation to solve for c:

x^2 = 10^2 + 6^2 - 2 * 10 * 6 * cos(0)

x^2 = 100 + 36 - 120

x^2 = 16

x = sqrt(16) = 4

Therefore, the length of the side x is 4.

To find the indicated angle, we can use the Law of Sines, which states that in any triangle, the ratio of the length of a side to the sine of the angle opposite that side is constant. In symbols, if a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the measures of the angles opposite those sides, then we have the equations:

a/sin(A) = b/sin(B) = c/sin(C)

In our case, we are given the lengths of two sides (a = 10 and c = 12) and the measure of the angle opposite one of those sides (A = 0 degrees), so we can use those values to solve for the measure of the angle opposite the other side:

10/sin(0) = 12/sin(C)

sin(C) = 0

Therefore, the measure of the angle C is 0 degrees.

The quadratic equation (x + 1)² / 46.667 - (y - 5)² / 56 = 1 represents the hyperbola in standard form.

In this question we find the equation of a hyperbola in general form, that is, a quadratic equation of the form A · x² + B · y² + C · x + D · y + E = 0, and we need to obtain the standard form of the hyperbola:

(x - h)² / a² - (y - k)² / b² = 1

Where:

We can switch from general form into standard form by completing the square, an application of algebra properties:

6 · x² - 5 · y² + 12 · x + 50 · y - 149 = 0

(6 · x² + 12 ·  x) - (5 · y² - 50 · y) = 149

6 · (x² + 2 · x) - 5 · (y² - 10 · y) = 149

6 · (x² + 2 · x + 1) - 5 · (y² - 10 · y + 25) = 149 + 6 + 125

6 · (x + 1)² - 5 · (y - 5)² = 280

(x + 1)² / 46.667 - (y - 5)² / 56 = 1
