The given statement expression is equivalent to -2 [tex]\frac{1}{10}[/tex].

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted [i], called the imaginary unit and satisfying the equation -

[tex]{\displaystyle i^{2}=-1}[/tex]

Every complex number can be expressed in the form a + bi, where [a] and [b] are real numbers

We have the following statement -

A Point-Slope equation of a straight line models this scenario: y -50,000 = -3,000(x -10).

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

We can recognize any points of the graph.

Given that;

y -50,000 =______(x -10)

We need to find the slope.

Slope = Change in y / Change in x

Slope = 80,000 - 50,000 / 0 - 10 = 30,000 / -10

The newspaper in Haventown had a circulation of 80,000 papers in the year 2000. In 2010, the circulation was 50,000. With x = 0 representing the year 2000, the graph below models this scenario.

In this case, we'll have to carry out several steps to find the solution.

Step 01:

SOLUTION:

Step 1:

we are to find the measure of minor arc cut off by one of the diagonals;

The sum of interior angles in a pentagon is:

Each interior angle of a regular pentagon is

So the size of the major arc can be gotten by the circle theorem; the angle at the centre is twice the angle at the circumference.

Then recall,

Step 2:

We are to find the length of the same minor arc in problem;

So the length of the minor arc, given that the radius is 10 cm is 8 pi

The slope-intercept form of the equation of a straight line is given to be:

where m is the slope and b is the intercept on the y-axis.

The slope is calculated using two points on the line by the formula:

Therefore, for this line, the slope will be:

Therefore, this value for the slope is substituted back into the equation for the line:

At the point (6, 0), we can calculate the value of b to be:

Therefore, the equation is:

Answer:

B (2, 3)

The two lines intersect near that point.

When we reflect a point over y = x, the x and y coordinates become swapped and switch places, that is why (x,y) results to (y,x).

Therefore, the answer is true.

we have the system

3x +y = -3

3x +y = 3

In this problem we have two different parallel lines

Remember that the solution of the system is the intersection point both lines

In this problem the lines don't intersect (are parallel)

therefore

the system has no solution NS

isolate the variable y in the first equation

y=-3x-3 -----> equation 1

isolate the variable y in the second equation

y=-3x+3 -----> equation 2

Solve the system of equations

equate equation 1 and equation 2

-3x-3=-3x+3

solve for x

-3x+3x=3+3

0=6 ------> is not true

that means

the system has no solution (NS)

The difference between the two investments after 35yrs is $4700 and  Bank of America is offering higher interest than 5/3rd banks.

Most interest is compounded semiannually, quarterly, or monthly. Continuous compounding assumes that interest is compounded indefinitely and reentered on the balance sheet. The continuous compounding formula takes into account four variables.

For the given question,

5/3rd bank offers continuous interest:

For continuous interest, A = P[tex]e^{rt}[/tex]

where,

P = the initial amount

A = the final amount

r = the rate of interest

t = time

e is a mathematical constant where e ≈ 2.7183.

A = 10000 × [tex]2.71^{0.042*35}[/tex]

A =  10000 × 4.04

A = $40400 approximately

Interest = Amount - Principle

Interest = 40400 - 10,000

Interest = $30400

Bank of America offers compound interest:

For compound interest:

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

A = 10000 × 4.51

A = $45100

Interest = Amount - Principle

Interest = 45100 - 10,000

Interest = $35100

The above calculation explains Bank of America is offering higher interest than 5/3rd bank by $35100 - $30400 = $4700

The length of each piece of wire is 2.5 inches.

Fractions are used to depict the components of a whole or group of items. Two components make up a fraction. The numerator is the number that appears at the top of the line. It specifies how many identically sized pieces of the entire event or collection were collected. The denominator is the quantity listed below the line. The total number of identical objects in a collection or the total number of equal sections that the whole is divided into are both displayed. A fraction can be expressed in one of three different ways: as a fraction, a percentage, or a decimal. The first and most popular way to express a fraction is in the form of the letter ab. Here, a and b are referred to as the numerator and denominator, respectively.

Let the number of pieces = x

A is the equation representing proportional relationship .

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.

If the y intercept is anything but 0, then the linear function is not proportional. So C is not proportional (2 is the y intercept)

B is a quadratic and it will not give proportional results. y/x is not a constant.

D has no x value and is not going to give a proportional result. y/x is undefined.

Answer:

x = 1.5°

Step-by-step explanation:

8 days = 12°

1 day = x

cross-multiply

8x = 12

Divide both sides by the coefficient of x, which is 8

8x/8 = 12/8

x = 1.5°

Hence, 1 day = 1.5°

The values of c and d that would make that the given expression represent a real number are c = –3, d = –2.

For the given question;

The expression is given as;

Simplify the expression;

= i(2c + 2di + 3ci + 3di²)

= 2ci + 2di² + 2ci² + 3di³

= (2c - 3d)i - 2d - 3c

In order is for expression to yield a real number, the coefficient of must now be zero.

Check the values from option;

2c - 3d = 2 x 2 - 3x 3 = -5

2c - 3d = 2 x -2 - 3 x -3 = -13

A line in slope-intercept form is represented by the following equation:

Parallel lines have the same slope, then if the line is parallel to the line y=-2x+5, the slope of the parallel line would be -2 too.

Now, by the given point (2,1) and knowing the slope of the line, we can use the slope-point form of the line equation to get the slope-intercept form:

Substituting:

Notice that the parallel line would be the same original line, y=-2x+5.

Answer:

Square footage

Step-by-step explanation:

The linear equations of the graph are y = 2/3x + 1. Option D.

Solution:

Let's find the slope of the graph using the coordinates (0, 1) (-3, -1)

m = y₂ - y₁ / x₂ - x₁

m = -1 - 1  / -3 - 0

m = -2/-3

m = 2/3

Using the slope-intercept form,

y = MX + c

where

m =  slope

c = y-intercept(This is when x = 0)

Therefore,

c = 1

Finally, the equation will be y = 2/3 x + 1.

The number of advance and same day tickets sold are 25 and 35 respectively.

let

25x + 30y = 1800

From (1)

x = 65 - y

Substitute x = 65 - y into (2)

25x + 30y = 1800

25(65 - y) + 30y = 1800

1625 - 25y + 30y = 1800

5y = 1800 - 1625

5y = 175

y = 175/5

y = 35

Substitute y = 35 into (1)

x + y = 65

x + 35 = 65
