What is System of Linear Equation ?An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, whereas B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason.
The cost of adult ticket be x and child ticket be y respectively.
Now as per sum ,
(i) 5x + 13y = 59 and,
(ii) 5x + 9y = 47
Subtracting equation (ii) from (i) we get,
13y - 9y = 59 - 47
⇒ 4y = 12
⇒ y = 3
putting y = 3 in equation (ii) we get
5x + 9*3 = 47 ⇒ x = 20/5 = 4
The cost of Adult ticket is $ 4 and Cost of Children ticket is $ 3.

Mc Graw Hill < 3-8 Slope and Equations of Lines Question 10 of 12 ✓ Question 10 X = D Find the value of x that satisfies the given conditions. Then graph the line on a separate sheet of paper. The line containing (4, -2) and (x,-6) is perpendicular to the line containing (-2,-9) and (3,-4).
To solve the problem, we must first find the slope of the line containing (4, -2) and (x, -6). The slope of a line is calculated as the change in y-coordinates divided by the change in x-coordinates, or (y2 - y1) / (x2 - x1). In this case, the slope of the line containing (4, -2) and (x, -6) is (-6 - (-2)) / (x - 4) = -4 / (x - 4)
Since the line containing (4, -2) and (x,-6) is perpendicular to the line containing (-2,-9) and (3,-4), we know that the product of the slopes of these two lines is -1. We can use that information to find the slope of the second line: -1 = (-4 / (x - 4)) * m, where m is the slope of the second line. Solving for m, we get m = -1 / (-4 / (x - 4)) = (x - 4) / 4.
We can now use the point-slope form of a linear equation to find the equation of the line containing (-2,-9) and (3,-4). The point-slope form is y - y1 = m(x - x1). In this case, we can use (-2,-9) as (x1, y1) and (x - 4) / 4 as m:
y - (-9) = (x - 4) / 4 * (x + 2)
Simplifying we get y = (x-4)/4 + (-9) = (x-4)/4 - 9
Now we can substitute x = -2 and y = -9 to check if it belongs to this line:
-9 = (-2 - 4)/4 - 9
-9 = -2/4 - 9
-9 = -0.5 - 9
-9 = -9.5
It match so this line is the correct one.
The value of x that satisfies the given conditions is x = -2
You can graph this line on a separate sheet of paper by plotting the point (-2, -9) and using the slope (x-4)/4 to find additional points on the line.

What's the quotient in division?
The quotient is the number that is generated when we perform division operations on two numbers, and the result of the division is called the quotient.
There are four main terminologies used in the arithmetic division such as divisor, dividend, quotient, and remainder.
The number is divided by another number to get a different number as an output.
Dividend = Quotient × Divisor + Remainder
If the remainder is equal to 0, then;
Dividend = Quotient × Divisor
Therefore,
Quotient = Dividend ÷ Divisor
Dividend: The number which is required to be divided
Divisor: The number which divides the given dividend
Remainder: The number which is left after the division method. When a number is completely divided then the remainder is zero.

What is exponential form examples?
Exponential form is a way of representing repeated multiplications of the same number by writing the number as a base with the number of repeats written as a small number to its upper right.
In the exponential form, the exponent indicates the number of times the base is used as a factor.
For example, in the case of 16 it can be written as 2 × 2 × 2 × 2 = [tex]2^{4}[/tex], where 2 is the “base” and 4 is the “exponent.
A product in which the factors are identical is called a power of that factor. The number that is repeated is called the base, and the number of times it repeats is called the exponent, power or degree. And the power that is written on the right upper side are called exponents. when multiplying the numbers having same base and different exponents then the base is kept same and the exponents are added.

How do you find the factor of a remainder theorem?
The Remainder Theorem states that if a polynomial P(x) is divided by (x - c), the remainder is P(c). To find the factor of a polynomial using the Remainder Theorem, you can use the following steps:
Start by assuming that the polynomial can be factored into (x - c) and some other polynomial Q(x).Divide P(x) by (x - c) using polynomial long division, and find the remainder R(x).Use the Remainder Theorem to set P(c) = R(c) = 0.Solve for c to find the value that makes P(c) = 0.Use the value of c found in step 4 to factor (x - c) out of P(x).Repeat the process with the remaining polynomial Q(x) until the polynomial is completely factored in.Example:
P(x) = x^3 + 3x^2 + 2x -6
Factor = (x-2)
P(2) = 8 + 12 + 4 - 6 = 0
