What pair of factors of -45 has a
sum of 4?

Answers

Answer 1

Answer:

9 and -5

Step-by-step explanation:

9*-5=-45

9+-5=4

Answer 2

The pair of factors is 9 and -5.

What is a factor?

The factor of a number is another number that can divide the first number without any remainder.

Let, one of the factors is x.

Then, the other factor is = -45/x.

Given,

x + (- 45/x) = 4

⇒ x - 45/x = 4

⇒  x - 45/x - 4 = 0

⇒  x² - 45 - 4x = 0

⇒  x² - 4x - 45 = 0

⇒ x² - 9x + 5x - 45 = 0

⇒ x(x-9) + 5(x-9) = 0

⇒ (x-9) (x+5) = 0

Hence, x = 9, -5.

A football stadium is capable of seating a maximum of m fans. For each game, the
amount of money that the stadium brings in as revenue is a function of the number of
people, n, in attendance. If each ticket costs $30.00, what is the domain of this function?

Answers

Answer:

The revenue depends on the number of people n that purchases tickets, knowing that each ticket costs $30.00, the total revenue will be:

f(n) = $30.00*n

Now, we also know that the stadium is capable of seating a maximum of m fans, so the maximum possible value for n is m.

Now, for the function f(n), we have that:

The domain is the set of the possible values of n

The range is the set of the possible values of f(n).

We want to find the domain.

First, the minimum possible value of n is 0, the case where nobody purchases a ticket.

The maximum possible value of n is m, this is the case where the stadium is full.

Then the domain will be:

D= {n,m ∈ Z, 0 ≤ n ≤ m}

Where we imposed that n must be an integer number because n represents a whole quantity.

The domain of the function should be [tex]0\leq n\leq m[/tex] where n and m are integers because they represent the number of people.

Given information:

A football stadium is capable of seating a maximum of m fans.

People attending the game are n.

The cost of each ticket is $30.

The  amount of money that the stadium brings in as revenue is a function of the number of  people, n.

So, the money will be calculated based on the attendance of people which implies that n will be the independent variable of the function.

So, the revenue generated can be written as,

[tex]f(x)=30n[/tex]

Here, the value of n represents the domain of the function.

Now, the maximum number of people allowed in the stadium is m as there are only m seats.

Therefore, the domain of the function should be [tex]0\leq n\leq m[/tex] where n and m are integers because they represent the number of people.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The number of batch recipe calls for 1 / 2 lb of flour = 1 batch

And to calculate the number of batches , we use

The number of batch recipe calls for 1 lb of flour will be

1 / 2 lb of flours = 1 batch

Multiplying by 2 on both sides , we find the number of batches for 1 lb of flour

Therefore , 1 / 2 x 2 = 1 x 2

1 lb of flour = 2 batches

3 / 4 lb of flour is 1 x 3 / 4 = 2 x 3 / 4

                                          = 3 / 2 batches

                                          = 1.5 batches

1 / 4 lb of flour is 1 x 1 / 4 = 2 x 1 / 4

                                        = 1 / 2 batches

                                        = 0.5 batch

Hence ,  The number of batches that can be made with 1 lb , 3 / 4 lb and 1 / 4 lb are 2 batches , 1.5 batches and 0.5 batch respectively

Answer:

−2(−9x+5)−4x=2(x−5)−4

Step 1: Simplify both sides of the equation.

−2(−9x+5)−4x=2(x−5)−4

(−2)(−9x)+(−2)(5)+−4x=(2)(x)+(2)(−5)+−4(Distribute)

14x−10=2x−14

12x−10=−14

Using the substitution of (y=y) what is y= -3x+5 y= -2x+3 (pls help this is)

Answers

Solving by substitution the answer would be X = 2 and Y = -1

Answer:

x = 2 and y = -1

Step-by-step explanation:

y = -3x + 5

y = -2x + 3

-3x + 5 = -2x + 3

Add 2x to both sides;

-x + 5 = 3

Subtract 5 from both sides;

-x = -2

Divide both sides by -1

x = 2

Solve for y;

y = -3x + 5

y = -3(2) + 5

y = -6 + 5

y = -1

Which linear inequality is represented by the graph?

Step-by-step explanation:

The linear equation of inequality is y ≤ ( x/2 ) + 2

What is an Inequality Equation?

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

Substituting the values in the equation , we get

The x intercept of the equation is when y = 0

So , A ( -4 , 0 ) is the x intercept

And , the y intercept is when x = 0

So , B ( 2 , 0 ) is the y intercept

Therefore , the inequality is y ≤ ( x/2 ) + 2 and the graph is plotted

Hence , the inequality is y ≤ ( x/2 ) + 2

In math formulas, A and a, always represent the same number.

Answers

Answer:  False

Step-by-step explanation:

In math formulas, we want to use different symbols to represent different things.

While in linguistics, A and a represent the same thing, the symbols are different, then we can use them to represent different things.

For example, we can define a square of side length a.

And the area of that square will be equal to the square of its side length, we can represent the area with A, such that:

A = a^2.

Here A and a are different numbers (and also represent different measures, a is in units of length and A is in units of surface).

The number of books sold by Holly and Ethan to get a profit of $30 will be 20.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Holly and Ethan decide to sell some of their books at a flea market. The booth rental costs $15, and they will sell each book for $1.50.

The number of books will be calculated as,

1.5x = 30

x = 30 / 1.5

x = 20

Bill has two fat cats. He feeds each cat 150 grams of dry food each, twice a day. If he buys a 5 kilogram bag of dry food, about how many days will the bag last?

Answers

Answer: 4 days (I think)

Step-by-step explanation:

One cat = 150*2 = 300g

Two cats = 600g

600*2 = 1200 (this is the total amount of food they both eat in a day)

5kg = 5000g

1200g/5000g = 4.17
