What is a linear equation in two variables?

An equation is said to be a linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Let x number of tickets sold on Friday and y number of tickets sold on Saturday.

By using the given condition,

x + y = 360 ----------(I)

y =3x -------(II)

Put y = 3x in equation (I), we get

x + 3x = 360

4x = 360

  x = 90

Now put x = 90 in equation (I), and we get

90 + y = 360

y = 270

Hence, 90 tickets were sold on Friday and 270 tickets were sold on Saturday.

There will be only one solution to this question.

There is no input mapped into two or more outputs in the given relation:

(-3,4) (6,0),(-3,4),(-8,-2)

Thus, the relation is a function.

A relation maps elements of a set (inputs, usually defined by the variable x) into elements of another set (outputs, usually defined by the variable y).

So, for example, the coordinate pair (x, y) means that a relation is mapping the input x into the output y.

A relation is also a function if there is no input being mapped into two or more outputs.

For the case of the given relation:

(-3,4) (6,0),(-3,4),(-8,-2)

The mappings are:

-3  → 4   (this one appears twice)

6  → 0

-8  → -2

The elements in sets are separated by commas so they can be read easily.

Instead of describing the constituents of a set, a set-builder notation describes them. The elements are listed, for instance, in the set {5, 6, 7, 8, 9}. We interpret the collection of all x such that x is a counting number between 4 and 10 as the collection of all x.

In mathematics, a set is a logically arranged group of items that can be represented in either set-builder or roster form. Sets are typically denoted by curly brackets {}; for instance, A = {1, 2, 3, 4} is a set.

The sequence of elements (separated by commas) between the curly braces " and "in mathematics form an unordered group of elements known as a set. For instance, the domesticated animals {cat, cow, dog} , the odd numbers {1, 3, 5, 7, 9} and the alphabets {a, b, c, d, e} are all sets. So they can be read or interpreted easily.

Answer:

4 1/3, 4.337, 35/8, 4.44

Step-by-step explanation:

4.337, 4 1/3, 35/8, 4.44

4 1/3 = 13/3 = 4.333

35/8 = 4.375

So, the order from least to greatest is: 4 1/3, 4.337, 35/8, 4.44

Answer:

4 1/3, 4.337, 35/8, 4.44

Step-by-step explanation:

"order from least to greatest" means put the smallest first and each next one bigger and the biggest one last.

Change everything to decimals to compare.

A fraction bar is just a division symbol.

1/3 means 1÷3 which is .33333...

4 1/3 = 4.33333...

35/8 means 35÷8

= 4.375

Smallest is 4.333...

So 4 1/3 goes first.

Then 4.337 and next 35/8 (bc 4.375)

Last is biggest 4.44 so it goes last.

In order from least to geatest is:

4 1/3, 4.337, 35/8, 4.44

The region of the line greater than 3 and less than 5 that number is 4.

The compound inequality x > 3 or x < 5 is 4 , that set of all real numbers.

Therefore, the solution to this problem is  (x - 2)(x + 3) are the factors of p(x) (2x - 5).

An equation is a mathematical statement that is created by connecting two expressions using the equivalent sign. An example of an equation is 2x - 5 = 15. By resolving this equation, we may ascertain that the variable x has a value of 5.

Here,

Given, the polynomial in this case is 2x3 - 3x2 - 17x + 30.

It is necessary to factor the polynomial.

Let p(x) equal 2x3, 3x2, 17x, and 30.

P(xconstant )'s term is 30.

Factors of 30 are equal to 1, 2, 3, 5, 6, 10, 15, and 30.

Consider x = 2.

Replace x = 2 in p. (x),

2(2)³ - 3(2)² - 17(2) + 30 =p(2)

=> 2(8) - 34 - 3(4) + 30

= >16 - 16

= 0

So, x - 2 is a factor of 2x³ - 3x² - 17x + 30.

Now splitting the x² and x terms,

2x³ - 4x² + x² - 2x - 15x + 30= 2x³ - 3x² - 17x + 30

=> x(x - 2) - 15(x - 2) +  2x²(x - 2)

= > (x - 2)  *  (2x² + x - 15)

factoring  2[tex]x^{2}[/tex] + x - 15

= 2[tex]x^{2}[/tex] + 6x - 5x - 15

= - 5(x + 3)  +  2x(x + 3)

= (x + 3)(2x - 5)

After one half-life, 50% remain in the initial parent nuclei, 25% after two, and so on. The amount of radiation emitted by a radioactive source depends on both its half-life and the initial number of radioactive atoms present.

Atoms strive for stability, thus they release energy from their nucleus in the form of a particle or ray to achieve a more stable state.

The unstable atom is referred to as a radioactive atom, the process is known as radioactivity, and the energy emitted is radiation.

If these forces are out of balance or if the nucleus has an excessive amount of internal energy, an atom is unstable (radioactive).

An overabundance of neutrons or protons can make the nucleus of an atom unstable.

The initial parent nuclei still contain 50% of them after one half-life, 25% after two, and so on.

The half-life and the initial quantity of radioactive atoms present both affect how much radiation is produced by a radioactive source.

Therefore, after one half-life, 50% remain in the initial parent nuclei, 25% after two, and so on. The amount of radiation emitted by a radioactive source depends on both its half-life and the initial number of radioactive atoms present.

Answer:

f(x) = 6 * sin(2x) - 10

Step-by-step explanation:

We can use the given information to write the general formula of a sinusoidal function as follows:

f(x) = A * sin(B(x - C)) + D

The amplitude of the function, A, is equal to the difference between the maximum and minimum values of the function, which in this case is -10 - (-4) = 6.

The period of the function, B, is equal to the distance between consecutive maximum or minimum points, which in this case is 2 - 0 = 2.

The phase shift of the function, C, is equal to the horizontal shift of the entire function, which in this case is 0 since the minimum point is at x = 0.

The vertical shift of the function, D, is equal to the y-coordinate of the minimum point, which in this case is -10.

Therefore, the formula of the given function is:

f(x) = 6 * sin(2(x - 0)) - 10

We can simplify this formula by removing the unnecessary parentheses and constants:

f(x) = 6 * sin(2x) - 10

This is the final formula for the given sinusoidal function, where x is entered in radians.

to do this, find a value of x or y from one equation and plug it into the other. let's use x in this case

so we have 13x-6y=22 and x=y+6

for the x value of the first equation, plug in x=y+6 from the second equation to get:

13(y+6)-6y=22

then you solve for y,

13y+78-6y=22

7y=-56

y=-8

then to solve for x, plug in your y value to either of the first 2 equations. lets use x=y+6

The geometric sequence 2, −6, 18, −54, ... to represent the 9th term is

d. f(9)=f(8)+3(8)

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the previous one by a fixed, non-zero number, called the common ratio. In the given sequence, the common ratio is -3, so the nth term of the sequence can be found by multiplying the previous term by -3.

Using the recursive formula for a geometric sequence, the nth term can be found by multiplying the first term, f(1), by the common ratio raised to the (n-1) power, or f(n) = f(1)•(-3)^(n-1). In the given sequence, f(1) is 2, so the 9th term can be found by multiplying 2 by -3 raised to the 8th power, or f(9)=f(1)•(-3)^8.

Alternatively, the nth term can also be found by multiplying the previous term, f(n-1), by the common ratio, or f(n) = f(n-1)•(-3). Since the 8th term in the given sequence is -54, the 9th term can be found by multiplying -54 by -3, or f(9)=f(8)•(-3).

Therefore, the 9th term in the given sequence is -486 and the correct answer is d. f(9)=f(8)+3(8).
