18x - 2y=0

Now we can explore many different combinations but I will give you something simple

18(1) - 2(9)=0  (note that two numbers beside each other means multiplication)

The proof is given as follows:

The transitive property argues that "if two quantities are equal to the third quantity, then we may claim that all the quantities are equal to one other".

The term transitive refers to a transfer. If there are three quantities a, b, and c, and if an is connected to b by some rule and b is related to c by the same method, then a and c are related to each other by the same rule; this property is known as the transitive property of equality.

D -3/2 is the right answer. In other words, the sum of their slopes is -1. So, if the green line has a slope of 2/3, the red line has a slope of -3/2.

The slope of a line indicates its steepness. Slope is computed mathematically as "rise over run" (change in y divided by change in x). The slope of a line is its steepness as it goes from LEFT to RIGHT. Slope is the ratio of a line's rise, or vertical change, to its run, or horizontal change. The slope of a line is always constant (it never changes) regardless of whatever two locations on the line are chosen. The slope-intercept form of an equation occurs when the equation of a line is stated in the form y = mx + b. The slope of the line is given by m.

Here,

The correct answer is D -3/2 that is, the product of their slopes is -1. So, if the slope of the green line is 2/3, then the slope of the red line is -3/2.

If Hiba needs 40g of sugar to make 15 biscuits. The amount of flour she needs is 480g and the number of packs of butter will she have to buy is 3 pack of butter.

a. Amount of flour she needs

Amount of flour she needs =(3×40) × 60/15

Amount of flour she needs = 120 × 60/15

Amount of flour she needs = 480g

b.  Packs of butter will she have to buy

Packs of butter needed = [(2×40) × 60/15] /125g

Packs of butter needed = [80 × 60/15] /125g

Packs of butter needed = 320 /125g

Packs of butter needed = 2.56

Packs of butter needed = 3 packs (Approximately)

Therefore , the solution of the given problem of mean comes out to be

23.679 the isotopic mass of the least abundant isotope.

The arithmetic mean, often known as the average, of a dataset is the total of all values divided by the number of values (as opposed to the geometric mean). It is the most used often index of central tendency, sometimes known as the "mean." This result can be obtained by simply dividing the number of variables values in the dataset by the sum of all the values.

Here,

The abundant isotope has an isotopic mass of 123.39 u, compared to the most prevalent isotope's mass of 121.560 u.

22.567 u is the average atomic mass.

84.236% is the most prevalent isotope.

22.653 u is the isotope's mass.

Least prevalent isotope: 100 - 84.236% = 15.764%

Take into account that x is the mass of both the least common isotope.

The same element's atoms called abundant isotopes have different quantities of neutrons than other isotopes. These species always have the same number of protons and electrons. Although there is a change in the number of neutrons, the atomic number is unaffected. The weighted value of all the isotopes that an element naturally presents is its atomic mass.

Average atomic mass is equal to the sum of the natural abundances of the isotopes A and x divided by 100.

=> 22.653 = ( 22.567 * 84.236) + (x * 15.764 ) / 100

=>22.653 * 100 = 1900.953 + 15.764 x

=> x = 22.653 * 100 - 1900.953/ 15.764

The cost of the car with sales tax would be $23,406.38.

Step-by-step explanation:

You can calculate this by adding the sales tax to the cost of the car:

$21,500 * 8.25% = $1,786.25

$21,500 + $1,786.25 = $23,286.25

The solution to the equations are as follows:

1. X^2 + 6X + 3 = 0, the solution is (-3,-1).

2. 52726 - 6 = 52,720

3. 12 - 8 + (-5) = -1

4. X^2 + 8X + 20 = 0, the solution is (-5, -4).

5. x⁻¹+4x⁻²=0

X^2 + 6X + 3 = 0, can be solved by the quadratic formula: X = (-b ± √(b^2 - 4ac)) / 2a, where a = 1, b = 6, and c = 3.

X = (-6 ± √(6^2 - 4 * 1 * 3)) / 2 * 1

X = (-6 ± √(36 - 12)) / 2

X = (-6 ± √(24)) / 2

X = (-6 ± 2√6) / 2

X = (-3 ± √6), (-3 - √6)

52726 - 6 = 52720

12 - 8 + (-5) = -1

X^2 + 8X + 20 = 0, can be solved by the quadratic formula: X = (-b ± √(b^2 - 4ac)) / 2a, where a = 1, b = 8, and c = 20.

X = (-8 ± √(8^2 - 4 * 1 * 20)) / 2 * 1

X = (-8 ± √(64 - 80)) / 2

X = (-8 ± √(-16)) / 2

Since the square root of a negative number is not defined in real numbers, there are no real solutions to this equation.

x⁻¹ + 4x⁻² = 0

AB² = (xb - xa)² + (yb - ya)² = (5 - 1)² + (4 - 1)² =

The current asset is $10,150, the total long term asset is $13108, the total current liabilities is $985, the long term liabilities is $9982 and the total equity is $12273

The company has $10,150 in current assets, which are made up of $8,250 in cash, $1,225 in inventory, and $675 in accounts receivable.

The company has $985 in current liabilities, which are made up of $485 payable to suppliers and a $500 loan that must be repaid in the following six months.

The owner's equity is equal to the $12,000 initial investment plus the $1,291 in earnings retained less the $2,018 in long-term loan repayment plus the $1,000 set aside for long-term investment, for a total of $12,273.

The value of the company's assets (land, buildings, and equipment) plus the owner's equity, or $12,273 + $8,878 + $4,230, equals the net worth of the business, or $25,381.

a) The current assets of the company are:

$8,250 in cash

$1,225 in inventory

$675 in accounts receivable

The current assets total $10,150.

b) The long-term assets of the company are:

Land and building worth $8,878

Equipment worth $4,230

The total long-term assets of the company are $8,878 + $4,230 = $13,108.

c)The current liabilities of the company are:

$485 owed to suppliers

$500 loan to be paid off in the next six months

The total current liabilities of the company are $485 + $500 = $985.

d)The long-term liability of the company is the five-year loan of $12,000, of which $2,018 has been paid back, leaving a remaining balance of

e) The total equity of Company X

= $12,000 (initial investment) + $1,291 (retained earnings) - $2,018 (repaid long-term loan) + $1,000 (long-term investment)

The slope of the line and a point on the line can be used to create the equation of a line. To better comprehend how the equation for a line is formed, let's learn more about the line's slope and the necessary point on the line. The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. The coordinate system's point with the x coordinate and the y coordinate is referred to as the point.

The equation of the line passing through the points (x1, y1), with a slope of m is given by the formula:

(y - y1) = m (x - x1)

Given that the point is (-4, 1) and the slope, m = -3/2.

Substituting the values we have:

(y - y1) = m (x - x1)

y - 1 = -3/2 (x - (-4))

2(y - 1) = -3(x+ 4)

2y - 2 = -3x - 12
