The given statement is False, because the description only applies to one solution. The solution set contains all conceivable solutions.

A linear number pattern is a succession of numbers with the same difference between each term. As an example, consider the numbers 1, 3, 5, 7, 9,... Every phrase differs by a factor of two. These are also known as linear numbers. Another example would be 7, 17, 27, 37,...

A formula can be found for linear sequences, that is, sequences in which the difference between succeeding terms is always the same. would have resulted in the formula un = 3n + 35. produces the formula un = 3n - 10, where c is either positive or negative.

To obtain the remaining phrases, you simply keep using the addition of 1 method.

Here are a few further illustrations of linear number patterns:

The system of equations involving y = 2x + 1 and y = 3x has the solution written as an ordered pair (1 , 3).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

y = 2x + 1     (equation 1)

y = 3x     (equation 2)

Since both equations are in the form of y in terms of x and some constant, substitute the second equation to the first equation.

y = 2x + 1     (equation 1)

3x = 2x + 1

Combining the all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.

3x - 2x = 1

x = 1

Substituting the value of x in the second equation,

y = 3x     (equation 2)

y = 3(1)

y = 3

Writing it as an ordered pair, we got (1 , 3) as the solution of the system of equations involving y = 2x + 1 and y = 3x.

Answer:

f(x) = 4 ÷ 5√x

The area is mentioned to be square, so its length will be the square root of x. 4-fifths of that same length are the length of 1 row of the bookshelves, therefore, this is your answer.

➲ Hope it helps!

Answer: 90 feet

Step-by-step explanation:

The function that expresses length f(x) feet, in terms of area x square feet can be written as:

f(x)  =  sqrt(x)

So, when x = 100 square feet,  f(x) = 10 feet,

when x  =  121 square feet, f(x)  =  11 feet,

when x = 8100 square feet, f(x)  =  90 feet

Slope of line=0

Slope of line=[tex]\frac{y2-y1}{x2-x1}[/tex]

=[tex]\frac{-4+4}{11-7}[/tex] =[tex]\frac{0}{4}[/tex] =0

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively.

The ratio of the "vertical change" to the "horizontal change" between (any) two unique points on a line is used to compute the slope.A declining line has a negative "rise." The line might be useful, as determined by a road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.

The slope's absolute value serves as a gauge for a line's steepness, incline, or grade. A steeper line is indicated by a slope with a higher absolute value. A line can be drawn in one of four directions: upward, downward, horizontal, or vertical.

Answer:

200 children and 300 adults

Step-by-step explanation:

No. of children = c

No. of adults = a

EQUATION 1:    a + c = 500

EQUATION 2 :  23c + 47a = 18700

a = 500 - c

23c + 47(500 - c) = 18700

23c + 23500 - 47c = 18700

-24c = 18700 - 23500

-24c = -4800

-4800/-24 = c

c = 200

a = 500 - 200

a = 300

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

Given function is

f(x)=7/3x -9

where x=-3.

Subtract x=-3 in the above function.
