When Merida divides her age by 3 and adds 5, the result is 9, now the equation becomes: 9 = (m + 3) ÷ 5.

The link between two expressions on each side of the sign is represented by a mathematical equation. One variable and an equal sign are often present.

The definition an equation in algebra is a mathematical expression that indicates the equivalence of two mathematical terms. In equation 6x + 11 = 14, for instance, the two expressions 6x + 11 and 14 are separated by the symbol "equal."

When Merida divides her age by 3 and adds 5, the result is 9, now the equation becomes: 9 = (m + 3) ÷ 5, this represents the situation where m is Merida's age.

Answer:

Step-by-step explanation:

You want to find the measure of the angle designated as ∠1, given the other two have measures of 40° and 30°. You also want the classification of the triangle based on its angles.

The sum of angles in a triangle is 180°.

  40° +∠1 +30° = 180°

  ∠1 = 110° . . . . . . . . . . . . subtract 70°

The classification of a triangle as acute, right, or obtuse is based on the measure of its largest angle. If that angle is 90°, the triangle is a right triangle. If it is less, the triangle is acute; if it is more, the triangle is obtuse.

The angle measure 110° is more than 90°, so this triangle is an obtuse triangle.

There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square.

quadratic equations

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).

factoring

factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.

Answer:

72,000kg

Step-by-step explanation:

So, we know that there are 640 bags.

Each bag has a mass of 120kg.

The mass shrinks at a ration of 15:16

So, we can think of the total mass as 120x640:

120*640

=

76,800kg

Next, we can think of the dried mass as 15/16 of the 76,800kg. This is because the dried ration was 15, and the orgninal ration was 16:

76,800/16

=

4,800kg

This isnt our end answer, next we have to multiply this by  15, to find the dried ration:

4,800*15

=

72,000kg

Domain

Range

Interval Notation

Let's organize what is given to us from the problem.

We are given a graph of a function.

We need to analyze the graph to determine the domain and range of the graph.

If we take a look at our x values, we see that our graph starts at x = 3 and continues infinitely.

∴ we can write the graph's x-values as [3, ∞), or x ≥ 3.

⇒ The domain of the graph is equal to x ≥ 3.

If we take a look at our y values, we see that our graph begins at y = 1 and also continues infinitely.

∴ we can write the graph's y-values as [1, ∞), or y ≥ 1.

⇒ The range of the graph is equal to y ≥ 1.

∴ the answer to the question is equal to:

A. D: x ≥ 3

    R: y ≥ 1

The options that are solutions to the problem are 1 and 4:

1) n less than or equal to 3, and

4) 3 greater than or equal to n   (since 3 ≥ n)

Step-by-step explanation:

Let's translate the e=words into expressions:

"five plus two times a number n"  becomes 5 + 2n

"is less than or equal to eleven" becomes ≤ 11

Put the two expressions together, with the word "is" and the "=" sign:

Solving:  

   2n  ≤ 11 - 5

   2n  ≤ 6

   n  ≤ 3

The options are:

1) n less than or equal to 3   Correct

2) 3 less than or equal to n   Incorrect.  3 is greater than or equal to n

The expected value of the winnings from a game is 2.1.

Expected value is used when we want to calculate the mean of a probability distribution. The weighted average of possible values of a random variable, with weights given by their respective theoretical probabilities, is known as the expected value.

Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11 gets 3a³ + 4a² - a + 5.

The answer in descending powers of a is 3a³ + 4a² - a + 5.

A polynomial is a mathematical expression consisting of a sum of powers in one or more variables (indeterminates) with non-negative integer exponents.

Adding the polynomial 3a³ + 8a - 6 and 4a² - 9a + 11                                        

(3a³ + 8a - 6) + (4a² - 9a + 11) = 3a³ + 4a² - a + 5

The coefficients of  a³, a², a and 1 is 3, 4, -1 and 5 respectively.                      

Descending powers of a in the polynomial is a³, a², a. So the answer in descending powers of a is 3a³ + 4a² - a + 5.

The relationship between the variables in the table is an inverse variation The equation to model is y = 42/x.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 8 is an equation.

We have,

x:  2  6  7  14

y: 21  7  6  3

Now,

When x = 2, y = 21

This can be written as,

y = kx

21 = 2k

k = 21/2

The equation is y = (21/2)x _____(1)

or

y = k/x

21 = k/2

k = 42

The equation is y = 42/x _____(2)

Now,

We will check which equation fits the table.

From (1)

y = (21/2)x

When x = 6,

y = (21/2) x 6 = 21 x 3 = 63

From (2),

When x = 6,

y = 42/6 = 7

When x = 7,

y = 42/7 = 6

When x = 14,

y = 42/14 = 3

This equation satisfies the table.

Thus,

The relationship is an inverse variation.

The equation is y = 42/x.

Answer:

36 candy bars. (32 if sold in packs)

Step-by-step explanation:

We know that eight candy bars cost 6 dollars, and we purchased $27 dollars worth of them.

Therefore, we can use 27/6 = 4.5 to see how many packs/sets of candy bars we purchased. Since there are 8 in a pack/set, we do 8x4.5 = 36 to see we can purchase 36 candy bars. However, if you can only buy them in packs of 8, then you can only purchased 4 packs/32 bars since 6x5 = 30 and we only have 27 dollars.

The factored form of quadratic equation 2x² + 7x + 3 is 2(x + 1/2) (x + 3)

A quadratic equation can be expressed in:

- Standard form: y = ax² + bx + c

- factored form: y = a(x - x₁) (x - x₂)

Here, x₁ and x₂ are the roots of the given function.

Suppose we are given a quadratic equation:

y = ax² + bx + c

To find the factored form, use the following properties:

x₁ . x₂ = c/a

x₁ + x₂ = - b/a

In this case, the quadratic function is:

y = 2x² + 7x + 3

We have to find x₁ and x₂ such that:

x₁ . x₂ = 3/2

x₁ + x₂ = - 7/2

Hence,

x₁ = - 1/2

x₂ = - 3

Therefore the factored form is:

y = 2(x + 1/2) (x + 3)
