Answer:

Step-by-step explanation:

5(a + a + b) = 5(2a + b)

use the distributive property:

a(b + c) = ab + ac

= 5 · 2a + 5 · b =10a + 5b

Answer:

\(\boxed{\sf{D. \quad 10a+5b}}\)

Step-by-step explanation:

Use a distributive property.

Distributive property:

\(\Longrightarrow: \sf{A(B+C)=AB+AC}\)

⇒ a+a=2a

Rewrite the problem down.

\(\Longrightarrow: \sf{5(2a+b)}\)

Multiply should be expanded.

⇒ 5*2a=10a

⇒ 5*b=5b

Rewrite the problem.

⇒ = 10a+5b

Answer:

$240 extra

Step-by-step explanation:

1/3(7200) + 12(420) = 2400 + 5040 = 7440

7440 - 7200 = 240

The customer had to pay 1720 extra.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A car is priced at $7200.

If the deposit is one third = 7200/3

                                          = 240

The amount after 12 payments will be

= 240 x 12

= 2880

total cost will be

= 2880 + 2400

= 5280

and, The customer had to pay extra amount

= 7200 - 5280

= 1720

Answer:

find the factors of c that add up to b

Step-by-step explanation:

Assuming you mean how to factorize a quadratic in the form:

ax² + bx + c ?

So when a = 1

find two numbers that have a product of c and a sum of b

So the answer is "find the factors of c that add up to b"

Answer:

Find the factors of c that add up to b.

Step-by-step explanation:

For example, if you were factoring

x^2 + 12x + 35

a=1

b=12

c=35

In order to factor, we're looking for what multiplies to 35, and adds up to 12. What multiplies to 35 are the factors of 35. In this case its 5 and 7.

5 × 7 = 35

5 + 7 = 12

So you could factor

x^2 + 12x + 35

= (x + 5)(x + 7)

The factoring method is a technique used to solve quadratic equations of the form ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable. To use the factoring method, we need to find two numbers that multiply to give c and add to give b. We then use these two numbers to factor the quadratic expression into two binomials, set each binomial equal to zero, and solve for x.

The format of a problem that can be solved using the factoring method should be in the form of ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable. The quadratic expression should be factorable into two binomials.

The factoring method can be applied to any quadratic problem that is in the correct format and is factorable. However, not all quadratic equations can be factored. In cases where the quadratic expression cannot be factored, we need to use other methods such as the quadratic formula or completing the square.

The main limitation of the factoring method is that it only works for quadratic equations that can be factored into two binomials. If the quadratic equation cannot be factored or if it has complex roots, then the factoring method cannot be used to solve the problem.

We make each factor equal to zero because if the product of two factors is zero, then at least one of the factors must be zero. Therefore, we set each factor equal to zero and solve for x to find the roots of the quadratic equation.

The correct probability of outcome D, based on the given table, is 3/13.

To determine the probability of D, we need to look at the given probabilities for each outcome. According to the table, the probability of outcome A is 1/13, the probability of outcome B is also 1/13, and the probability of outcome C is 1/13. We are interested in finding the probability of outcome D.

Since the sum of probabilities for all possible outcomes must equal 1, we can subtract the probabilities of outcomes A, B, and C from 1 to find the probability of outcome D.

1 - (1/13 + 1/13 + 1/13) = 1 - 3/13 = 10/13.

However, none of the given options matches the calculated probability. Therefore, we can conclude that none of the provided options accurately represents the probability of outcome D.

In conclusion, the correct probability of outcome D, based on the given table, is 3/13.

The change in one variable related to the change in more than one other variable is measured using multiple regression analysis.

A statistical method known as multiple regression is used on datasets intended to show a link between a single response or dependent variable and a number of independent factors.

Even though linear regression is frequently employed, it can only be utilized with one independent variable and one dependent variable. Non-linear regression is not predicted by linear regression, which is also limited to the training dataset.

We employ multiple regression to account for the same restrictions. It focuses on removing one particular limitation, which is allowing for the analysis of multiple independent variables.

 The total debt of the government at the end of year three is $7.2 billion.

Starting with a total debt of $5.5 billion, the government's deficits of $600 million in year one and $1.5 billion in year two contribute to an increase in the debt. However, in year three, the government runs a surplus of $400 million, which helps reduce the debt.

Thus, the total debt at the end of year three is calculated by adding the initial debt and deficits, and subtracting the surplus. In this case, the total debt at the end of year three is $7.2 billion.

Assuming the government runs a deficit of $200 million in year three, the calculation changes. With the initial debt of $5.5 billion, the deficits of $600 million in year one and $1.5 billion in year two, and the additional deficit of $200 million in year three, the total debt at the end of year three would be $7.8 billion. This demonstrates how the deficit amounts impact the overall debt accumulation.

If a government runs a budget deficit of $5 billion each year for ten years, resulting in a total deficit of $50 billion, followed by a surplus of $2 billion per year for five years, reducing the debt by $10 billion, and then maintaining a balanced budget for another ten years, the government debt would amount to $40 billion. The deficits over the initial ten years lead to a significant accumulation of debt, but the subsequent surpluses help mitigate the debt by reducing the deficit. Finally, the balanced budget in the later years ensures that there is no further increase in debt. Understanding the interplay between deficits, surpluses, and a balanced budget is crucial to grasp the long-term implications on government debt and fiscal stability.

The true statement is: c−a={3,5,9,15}.

Given sets a and c:

a = {x ∈ : x is even}

c = {3, 5, 9, 12, 15, 16}

To find c−a (the set difference between c and a), we need to subtract the elements of set a from set c.

Since set a consists of even numbers, and set c contains both even and odd numbers, the elements in set a will be subtracted from set c.

From the given sets, the common elements between c and a are 12 and 16. Thus, these elements will be removed from set c.

Therefore, c−a = {3, 5, 9, 15}. This is the set difference between c and a, which includes the elements that are in set c but not in set a.

The explicit formula for an arithmetic sequence calculator is a_n = a_1 + (n-1)d.

The formula for an arithmetic sequence is:

a_n = a_1 + (n-1)d

where a_n is the value of the nth term in the sequence, a_1 is the value of the first term in the sequence, n is the position of the term you want to find, d is the common difference between consecutive terms in the sequence, To use this formula to find a specific term in the sequence, simply substitute the values of a_1, n, and d into the formula and evaluate.

For example, if you wanted to find the 10th term in an arithmetic sequence with a first term of 3 and a common difference of 4, you would use the formula

a_10 = 3 + (10-1)4

a_10 = 3 + 36

a_10 = 39

Therefore, the 10th term in this sequence is 39.

Step-by-step explanation:

This means that for every unit increase in the x-coordinate, the y-coordinate decreases by 11/12 units.To find the slope of the line that contains the points (-3, -5/2) and (3, -8), we can use the formula for slope:

slope = (y₂ - y₁) / (x₂ - x₁)

Let's plug in the given coordinates into the formula:

slope = (-8 - (-5/2)) / (3 - (-3))

Simplifying the numerator and denominator:

slope = (-8 + 5/2) / (3 + 3)

To combine the fractions in the numerator, we need a common denominator:

slope = (-16/2 + 5/2) / 6

slope = (-11/2) / 6

To divide fractions, we multiply the numerator by the reciprocal of the denominator:

slope = (-11/2) * (1/6)

Simplifying the multiplication:

slope = -11/12

Therefore, the slope of the line that contains the points (-3, -5/2) and (3, -8) is -11/12.

The negative sign indicates that the line is sloping downwards from left to right. The magnitude of the slope (11/12) represents the steepness of the line.
