The graph of the equation shown above has infinite number of solutions.

In Mathematics, no solution is sometimes referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.

In Mathematics, an equation is said to have an infinitely many solution (infinite number of solutions) when the left hand side and right hand side of the equation are the same or equal.

Since the line representing this equation extends infinitely, we can reasonably infer and logically deduce that it has infinitely many solution (infinite number of solutions). Therefore, every point located on this line would satisfy the equation.

Answer:

250 adult tickets

Step-by-step explanation:

s = number of student tickets

a = number of adult tickets

s = a - 56  ==> 56 fewer student tickets sold than adult tickets

s + a = 444   ==> 444 total tickets were sold

(a - 56) + a = 444  ==> plug in a - 56 for s to solve for one variable

a - 56 + a = 444

a + a - 56 = 444  ==> combine like terms

2a - 56 = 444

2a = 500  ==> add 56 on both sides

a = 250 adult tickets

s:

s + a = 444

s + 250 = 444 ==> plug in 250 for a

s = 194 student tickets sold

a - s = 56

250 - 194 = 56 √

Hence, the difference between the number of student and adult tickets is 56.

Mean of the set of numbers = 23

Median of the set of numbers = 23

Mode of the set of numbers = 16, 19, 23, 26, 31

The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. This is what is most often meant by an average. The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.

Given numbers,

26, 31, 19, 23, 16

Putting in Ascending order

16, 19, 23, 26, 31

No. of elements N = 5

Mean = (26 + 31 + 19 + 23 + 16)/5

Mean = 115/5

Mean = 23

Since N = 5 (Odd)

Median = (N+1)/2th term

            = (5+1)/2th term

            = 6/2th term

            = 3rd term

            = 23

Every element has same frequency,

Mode = 16, 19, 23, 26, 31

Hence, Mean = 23, Median = 23 and Mode = 16, 19, 23, 26, 31

This can be proved by considering triangle BOC and triangle BAC as right triangles. The sum of the angles in a triangle is 180°, and in a right triangle, one of the angles is 90°. So, in each of triangles BOC and BAC, the sum of the other two angles must be 90°.

A triangle is a geometric shape that consists of three points, called vertices, connected by three line segments, called sides. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified based on their sides (equilateral, isosceles, scalene) and their angles (acute, right, obtuse).

Answer:

y = 7x - 7

Step-by-step explanation:

The equation for the function can be found using the slope-point form of a linear equation: y = mx + b, where m is the slope of the line and (x, y) is a point on the line.

To find the slope, we can use the two points:

m = (35 - 21) / (12 - 4) = 7

To find the y-intercept, we can substitute one of the points and the slope into the equation:

21 = 7 * 4 + b

Solving for b, we get:

b = 21 - 28 = -7

So, the equation of the line is:

y = 7x - 7

Answer:

5 feet

Step-by-step explanation:

Let's call the width of the rectangle "w". Then, the length would be "w + 7".

The perimeter of the rectangle is given as 34 feet, so we can set up an equation using the two sides of the rectangle:

2w + 2(w + 7) = 34

Expanding the second term and simplifying the equation, we get:

2w + 2w + 14 = 34

4w + 14 = 34

4w = 20

w = 5

Therefore, the width of the rectangle is 5 feet.

The equation which is used to represent the ages of Pierre and Claude is given by p = c + 3.

Linear equation in two variables can be written in the form of ax + by = c where a, b and c are constant terms and x, y are independent and dependent variables respectively. Here in this question the age of Pierre is represented as p and the age of Claude is represented as c. Since, Pierre is 3 years older than Claude then the equation representing their age can be formulated as:

p = c + 3 where p is Pierre's age and c is Claude's age and this represents that Pierre's age will be given when we will add 3 years more in the age of Claude.

Thus, the equation representing the age of Pierre is p = c + 3.

20 is 8 less than 28 as 3x-5 is 10 less than 3x-5+10.

Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given that, 20 is to 28 as 3x-5 is to 3x-5+10

We see, 28-20 = 8

That mean, we need to add 8 to 20 or subtract 8 from 28 to make both equal,

Therefore, we can say, 20 is 8 less than 28, or 28 is 8 more than 20,

Similarly,

3x-5 and 3x-5+10

We see, 3x-5+10 - (3x-5)

That mean, we need to add 10 to 3x-5 or subtract 10 from 3x-5+10 to make both equal,

For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".

Given that,

With the second option, Juliet would receive a monthly salary of $1200 + 0.02x,

We want to find the value of x such that this salary is equal to $1260, so we can set up the following equation:

$1200 + 0.02x = 1260

Subtracting $1200 from both sides:

0.02x = 60

A. No, this set is not a vector space. The set of all skew-symmetric 3x3 matrices does not contain the zero matrix, which is a requirement for a vector space.

B. Yes, this set is a vector space. The dimension is 2, and the basis is the functions y(x) = cos(2x) and y(x) = sin(2x). To verify this is a vector space, we need to check that the set is closed under addition and scalar multiplication. For arbitrary real constants a and b, the function y(x) = a cos(2x) + b sin(2x) is a linear combination of the basis vectors.
