See steps below for proving n = 2m:

An equation is formed of two equal expressions. n=2m can be proved by solving the two of the given equation for h and then equating them together as shown below.

An equation is formed when two equal expressions are equated together with the help of an equal sign ''=''.

Given the two equations, 2n=m+h, and h=n+m. Now, solve the two of the equations for h as shown below:

Equation 1.

2n = m + h

2n - m = h

h = 2n - m

Equation 2.

h = n + m

Further, equate the value of h from both the equation,

h = h

2n - m = n + m

Bring the like terms on the same side of the equation,

2n - n = m + m

n = 2m

Hence, proved n=2m.

Answer:

the answer to this should be no solution

Step-by-step explanation:

the first step would be adding seven to both sides, but all that does is leave a zero on the other side, so the equation ends up being 9x=0.

The value of x in the expression is 0.

We have,

Expression: 9x - 7 = -7

To solve for x.

Add 7 on both sides.

9x - 7 + 7 = -7 + 7

9x = 0

x = 0

Thus,

The value of x in the expression is 0.

Answer:

x^3y^2√xy

Step-by-step explanation:

First, you calculate what's in the square root. x^2 becomes x and y^4 becomes y^2.

Then you distribute the 1/2 to the x^5 and the y so they become x^5/2 and y^1/2.

Next, you combine the like terms. x and x^5/2 becomes x^7/2. y^2 and y^1/2 become y^5/2.

So you have x^7/2 y^5/2

To get rid of the 2 on the bottom of the exponents you square root both variables.

So you get √x^7 y^5 (square rooted x^7 and y^5)

Simplify the square rooted problem to x^3 y^2 √xy

You get x to the third power y to the second power and square rooted xy.

Hugo needs 15 weeks to pay back his brother completely if he pays $2 a week.

What is an equation?

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.

According to the given question:

Hugo decided to pay $2 a week to his brother to buy a bicycle.

The equation y - 10 = - 2(x – 10) models the amount of money he owes for the bike, where x is the number of weeks and y is the amount of money he still needs to pay.

To pay back to the brother he must owe no money which is y = 0.

∴ The weeks needed is,

0 - 10 = -2(x - 10).

- 10 = -2x + 20.

2x = 30.

x = 15.

He needs 15 weeks to pay back completely.

The factors of y =x³-4x²-17x+60x are (x−3), (x−5) and (x+4)

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers. Any polynomial must have variable exponents that are non-negative integers. Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

Given:

y =x³-4x²-17x+60x

Let us assume that the factors are

(x−a), (x−b) and (x- c)

So, if x is either equal to a or b or c, y=0

and a⋅ b⋅ c=−60, which means a or b and c are factors of 60.

Thus, which factor of 60 (such as 2, 3, 5, 6, 10 etc.) makes y=0.

It is given that (x−3) is a factor of y

and, When we divide y by (x−3), we get x²−x−20

Similarly x=5 makes x²−x−20 equal and Dividing x2−x−20 by (x−5), we get (x+4)

Hence, the factors of y =x³-4x²-17x+60x are (x−3), (x−5) and (x+4)

The demand function for the marginal revenue function is p(x) = 0.02x² - 0.025x + 138.

Define Marginal revenue

Marginal revenue is a central concept in microeconomics that describes the additional total revenue generated by increasing product sales by 1 unit.

Given expression is,

R′(x) = 0.06x² − 0.05x + 138

To make R'(x) to R(x) just integrate R'(x),

R(x) = ∫ R'(x) dx

      = ∫ (0.06x² − 0.05x + 138) dx

      =  0.06x³/3 − 0.05x²/2 + 138 x  + C

We get, R(x) = 0.02x³ − 0.025x² + 138 x  + C

It's given, the revenue is 0 means no items sold so R(0) = 0.

Now, put x = 0 and find C

R(0) = 0.02(0)³ − 0.025(0)² + 138 (0)  + C

   0 = 0 + C

C = 0

So, R(x) = 0.02x³ − 0.025x² + 138 x, since C = 0

Now, take x common from R(x) will give us,

R(x) = x( 0.02x² − 0.025x + 138 )

so, R(x) = x p(x)

so, p(x) = 0.02x² − 0.025x + 138

Hence, the demand function for the marginal revenue function is p(x) = 0.02x² - 0.025x + 138.

Using the concept of probability, the probability of not landing on yellow or red at all is 1/4.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Creating a square model of the two spins :

Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)

___ R ___ B ___ G ___ Y

R_ RR __ RB __ RG __ RY

B_ BR __ BB __ BG __ BY

G_ GR __GB __ GG __GY

Y_ YR __ YB __ YG __ YY

Sample space = 4² = 16

Combinations without red and yellow :

{BB, BG, GB, GG}

Number of selections without red or yellow = 4

Recall :

Probability = required outcome / Total possible outcomes

P(without Red or Yellow) = 4/16 = 1/4

Hence, the probability of not landing on yellow or red at all is 1/4.

Answer:2x^3+3x^2-11x-6

Step-by-step explanation:

The probability that Lucia receives (Head, Tail, Head) within this order is 1/8.

A coin toss has a total of two possible outcomes.

Three coin flips have a total of eight outcomes possible: 2 x 2 x 2 = 8

Positive result = (Head, tail, Head) in that sequence

i.e., 1 is the number of favourable results.

As we well aware,

Probability = favourable outcome / total outcome

The needed probability follows as a result.

Probability (first head) = 1/2

Probability (second tail) = 1/2

Probability (third head) = 1/2

Thus,

Probability(Head, tail, Head) = 1/2 x 1/2 x 1/2

Probability (Head, tail, Head) = 1/8

Consequently, the likelihood that she receives (Head, Tail, Head) within this order is 1/8.

The house value is decreased by $33840 and the current value of the house is $342160

Here, we have been given a house on the market was valued at $376,000.

We need to find the amount by which the house value decreased in dollar and the current value of the house.

The 9 percent of $376,000

376,000 * (9/100) = 33840

This means, the house value is decreased by $33840

So, the current value would be,

The 20% Tony spends from his monthly salary on the wallet, the bag which cost $20 more than the wallet and the ratio of the wallet to shoe cost of 5:6, which expressed as a fraction is 5/6, indicates;

(a) Tony's monthly salary is $2,400

(b) The amount spent on the pair of shoes is (6/25) of his monthly salary

A fraction is a part of a whole item, expressed as a quotient.

Let x represent Tony's salary, from the details of the question, we get;

The amount Tony spent on the wallet = 20% of his salary

The cost of the bag Tony bought = $20 + The cost of the wallet

Ratio of the cost of the wallet to the cost of the pair of shoes = 5:6

The amount Tony had left = $844

Therefore;

The amount Tony spent on the wallet = 20% of x = 0.2·x

Amount spent on the bag = 20 + 0.2·x

Ratio of the cost of the wallet to the cost of the pair of shoes = 5:6

Therefore;

Cost of the pair of shoes = (6/5)×(0.2·x)

Therefore;

x - 0.2·x - (20 + 0.2·x) - (6/5) ×(0.2·x) = 844

0.36·x - 20 = 844

x = (844 + 20)/0.36 = 2400

(b) The amount Tony spends on the pair of shoes = (6/5) × (0.2·x)

(6/5) × (0.2·x) = (6/5) × (2/10) × x = (12/50)·x = (6/25)·x

Answer:

x = 6 or x = 0 or x = -8

Step-by-step explanation:

Solve for x over the real numbers:

2 x^3 - 4 x^2 - 96 x = -8 x^2

Add 8 x^2 to both sides:

2 x^3 + 4 x^2 - 96 x = 0

The left-hand side factors into a product with four terms:

2 x (x - 6) (x + 8) = 0

Divide both sides by 2:

x (x - 6) (x + 8) = 0

Split into three equations:

x - 6 = 0 or x = 0 or x + 8 = 0

Add 6 to both sides:

x = 6 or x = 0 or x + 8 = 0

Subtract 8 from both sides:

Answer: x = 6 or x = 0 or x = -8
