What is the equation of the kind that passes through the point (3,-8) and has a slope of -4/3?

Answer:

This is true because the order of operations applies. In this case, we have to divide the 1/5 by 2 first and then get the result.

Dividing 1/5 by 2 is the same as multiplying 1/5 by 1/2, which is equivalent to multiplying the numerator and denominator by 1/2.

(1/5) * (1/2) = (1 * 1)/(5 * 2) = 1/10

So, (1/5)/2 = 1/10

This is also true because dividing a fraction by another fraction is the same as multiplying the first fraction by the reciprocal of the second fraction. The reciprocal of 2 is 1/2, and so dividing 1/5 by 2 is the same as multiplying 1/5 by 1/2.

That's why the answer is 1/10.

The inequality equation is given by m > -1

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

10 > -6m - ( -4 )   be equation (1)

On simplifying the equation , we get

10 > -6m + 4

Subtracting 4 on both sides of the equation , we get

6 > -6m

Divide by -6 on both sides of the equation , we get

m > -1

Therefore , the value of m is all numbers greater than -1

Hence , the inequality equation is m > -1

Answer:

7 sides is the answer of regular polygon

Area of region A is equal to the sum of area of region B and area of region C when a right-angled triangle is formed by the diameters of three semi-circular regions A, B, and C.

Let the diameters of semicircle A, B and C be a, b and c respectively.

We know area of a semi-circular region of diameter d is

A = (1/2)(πd²/4)

A = πd²/8

Thus,

area of region A is πa²/8

area of region B is πb²/8

area of region C is πc²/8

The triangle formed is a right angled triangle, with hypotenuse a and legs b and c. By Pythagoras theorem

a² = b² + c²

Multiplying both sides by π/8

(π/8)a² = (π/8)(b² + c²)

πa²/8 = πb²/8 + πc²/8

Area of region A = Area of region B + Area of region C

Hence proved.

The tax department used Simple Random Sampling, as they have chosen four districts randomly and audited everyone from those districts.

Simple Random Sampling is a method of selecting a sample from a larger population where every member of the population has an equal chance of being selected. In this case, every individual in the four randomly selected districts had an equal chance of being audited by the tax department. It is considered as the most basic form of probability sampling, and it is easy to implement and understand.

The main advantage of Simple Random Sampling is that it is highly representative of the population, if the sample is large enough, and if the sample is selected independently and randomly.

The future value of investment in 10 years for Steve will be $3,257.79 and for Gretta will be $5,187.48.

To find out how much money Steve and Gretta will have in 10 years, we need to calculate the future value of their investments using the compound interest formula:

FV = PV× (1 + r)ⁿ

Where:

FV is the future value of the investment

PV is the present value of the investment (i.e. the initial investment)

r is the annual interest rate (expressed as a decimal)

n is the number of years

For Steve:

PV = $2,000

r = 0.05 (5% expressed as a decimal)

n = 10

So, the future value of Steve's investment in 10 years will be:

FV = $2,000(1 + 0.05)¹⁰

FV = $3,257.79

For Gretta:

PV = $2,000

r = 0.10 (10% expressed as a decimal)

n = 10

So, the future value of Gretta's investment in 10 years will be:

FV = $2,000(1 + 0.10)¹⁰

x = -7, y = -1

Step-by-step explanation:

Solve the following system:

{12 y = x - 5 | (equation 1)

9 y - 2 x = 5 | (equation 2)

Express the system in standard form:

{-x + 12 y = -5 | (equation 1)

-(2 x) + 9 y = 5 | (equation 2)

Swap equation 1 with equation 2:

{-(2 x) + 9 y = 5 | (equation 1)

-x + 12 y = -5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{-(2 x) + 9 y = 5 | (equation 1)

0 x + (15 y)/2 = -15/2 | (equation 2)

Multiply equation 2 by 2/15:

{-(2 x) + 9 y = 5 | (equation 1)

0 x + y = -1 | (equation 2)

Subtract 9 × (equation 2) from equation 1:

{-(2 x) + 0 y = 14 | (equation 1)

0 x + y = -1 | (equation 2)

Divide equation 1 by -2:

The quotient of (x^3 + 8)/(x + 2) is x^2 - 2x + 4.

To find the quotient of (x^3 + 8)/(x + 2) we can use polynomial long division method.

First, divide x^3 by x and write down the quotient (x^2) and the remainder (0)

x^2(x + 2) = x^3 + 2x^2

So remainder is

(x^3 + 8) - (x^3 + 2x^2)

= -2x^2 + 8

Dividing -2x^2 by x gives -2x, so note down -2x

-2x(x + 2) = -2x^2 - 4x

So remainder is

(-2x^2 + 8) - (-2x^2 - 4x) = 4x + 8

Now dividing 4x by x gives a quotient of 4, so now the quotient all together is x^2 - 2x + 4

4(x + 2) = 4x + 8

So remainder is

(4x + 8) - (4x + 8) = 0

In the given question, we have to find the slope of the line whose equation 3x + 7y = 9.

The given equation is 3x + 7y = 9.

The slope-intercept version of the line's equation is what we need. In other words, we want y=mx+b in the form of ax+by=c. M is the slope and b is the y-intercept in the slope-intercept form.

To find the slope of the line convert the given equation in the general form of line by isolating the y.

Subtract 3x on both side, we get

7y = -3x + 9

Divide by 7 on both side, we get
