If the length of a rectangle is 3 cm less than twice the width of the rectangle and the perimeter is 75 cm, then the length is 24 cm and width is 13.5 cm
Consider the width of the rectangle as w
The length of a rectangle is 3 cm less than twice the width of the rectangle
The length of the rectangle = 2w-3
Perimeter of the rectangle = 75 cm
Perimeter of the rectangle =2(l+w)
Where l is the length and w is the width of the rectangle
Substitute the values in the equation
2(2w-3+w) = 75
2(3w-3) = 75
6w-6 = 75
6w = 81
w = 13.5 cm
The length of the rectangle = 2(13.5)-3
=24 cm
Hence, If the length of a rectangle is 3 cm less than twice the width of the rectangle and the perimeter is 75 cm, then the length is 24 cm and width is 13.5 cm

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let x be the number of members, and the number of non-members.
3x + 5y = 132
x = 2y
After solving the above two linear equations:
6y + 5y = 132
11y = 132
y = 132/11
y = 12 non-members
x = 24 members
Thus, the number of non-members is 12 and the number of members is 24.

The point at which a company's costs equal its revenues is the break-even point. C represents the cost, in dollars, of x
units of a product and R represents the revenue, in dollars, from the sale of x units. Find the number of units that must
be produced and sold in order to break even. That is, find the value of x for which C = R.
C = 13x +250 and R = 15.5x.
How many units must be produced and sold in order to break even?
4
The number of units that must be produced and sold in order to break even will be 100.
What is the break-even point?At the break-even point, the cost of the revenue is equal to the cost of the manufacturing.
The break-even point is the point at which a business's costs and revenues are equal. R stands for the revenue, in dollars, from the sale of x units, and C stands for the cost, in dollars, of x units of a product.
C = 13x + 250 and R = 15.5x
By the definition of the break-even point, then the equation is given as,
13x + 250 = 15.5x
15.5x - 13x = 250
2.5x = 250
x = 250 / 2.5
x = 100
The number of units that must be produced and sold in order to break even will be 100.

What does it mean to have a slope of “0”. Provide an equation as an example
When a line has a slope of 0, it means that the line is a horizontal line that is parallel to the x-axis. An equation that shows this is y = 0x + 2.
What is the meaning of a slope of 0?The slope of a line shows the change in the line and how it is shaped on the graph. If the slope of a line is 0, what it means is that the line has not slanting shape and is instead simply straight on the horizontal axis.
As a result of the line being a straight horizontal line, it will be parallel to the x-axis which is also a horizontal line.
Take the equation:
y = 0x + 2
y = 2
Y will be a horizontal line on y=2.

What is meant by Collinearity?Collinearity in geometry is the quality of a set of points being on a single line. Collinear points are a group of points that share this characteristic. The phrase has been used more broadly to refer to aligned objects, i.e., things that are "in a line" or "in a row."
The subject of geometry involves points, planes, and lines. A plane is a flat surface that can be either horizontal or vertical, whereas a line is a straight path that links two locations.
Understanding the offered figure and interpreting each question in light of the terminologies in it are necessary in order to answer the questions. As an illustration, collinear points are those that can be joined by a straight line, but non-collinear points cannot be connected by a straight line.

A) There are two parallel lines and a line that goes through them in this diagram. The line that goes through them causes perpendicular lines to form.
What are perpendicular lines?
Perpendicular lines are lines that intersect and create 90° angles. The two angles in this diagram are 90° due to this intersection.
B) There are two types of angles: supplementary and complementary: complementary angles are angles whose measurements add up to 90°. Supplementary angles are angles whose measurements add up to 180°. As you can see in this problem, the two angles (7x+11 and -1+8x) are 90°. When added they would equal 180°. These angles are supplementary.
C) Now that you know what supplementary angles are, you can use its characteristics to solve for x:
Since the two angles added up equal 180, write an equation that represents this: (7x+11) + (-1+8x) = 180Now, combine like terms: 10 +15x= 180Subtract both sides by 10: 15x= 170Divide both sides by 15 and you have your answer: x= 11.33D) Now, solve for the two equations by plugging in x [you final answers should be 90]:
(7x+11) = 7(11.33) +11 = 90.31 ≈ 90(-1+8x) = -1 + 8(11.33) = 89.65 ≈ 90

Use a graph of a polynomial G(x) to determine its zeros and the multiplicity of each zero. List the zeros from smallest to largest.
Zeros of a Polynomial
When a polynomial has a zero at x = a, then its graph 'touches' or 'crosses' the x-axis. If the zero has an even multiplicity (2, 4, 6, etc.), the graph 'bounces' off the x-axis.
We can see the graph crosses the x-axis 4 times and no bouncing occurs, so each zero has a multiplicity of 1.
From left to right, the zeros are:
x = -4 with a multiplicity of 1.
x = -2 with a multiplicity of 1.
x = 1 with a multiplicity of 1.
x = 3 with a multiplicity of 1.

How to determine a polynomial of least degree
A polynomials of least degrees includes all the roots and the given lead coefficient, which can used in the following formula:
p = a · Π (x - rₐ)
Where:
a - Lead coefficientrₐ - a-th root of the polynomial.If we know polynomial has rational coefficients, then the complex root 4 + i has a "twin" equal to 4 - i in accordance with the quadratic formula, otherwise the polynomial will have at least an irrational coefficient. Then, the least degree polynomial is introduced below:
p = 1 · (x - 3) · (x - 4 - i) · (x - 4 + i)
Then, we expand the expression by algebra properties:
p = (x - 3) · [x² - 8 · x - (16 - i²)]
p = (x - 3) · (x² - 8 · x - 17)
p = x³ - 8 · x² - 17 · x - 3 · x² + 24 · x + 51

Sidney has $85,450 in a savings account. The interest rate is 12% per year and is not
compounded. How much will she have in total in 1 year?
Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r
is the interest rate expressed as a decimal, and t is the time in years.
The amount that Sidney will have in her account in 1 year is $ 95,704.
Given that:-
Principal amount = $85,450
Interest Rate = 12 % per annum
i = prt
Where,
i represents interest,
p represents the principal,
r represents the interest rate, and
t represents the time (in years)
Hence, putting the values in the formula of simple interest, we get,

For [tex]f(x)[/tex] to be increasing, then [tex]f'(x) > 0[/tex], which is a positive rate of change. As you may have noticed, when [tex]x > 2[/tex], the value of [tex]f'(x)[/tex] is positive.

A traffic control engineer reports that 75% of the vehicles passing through a checkpoint are from within the state. What is the probability that fewer than 2 of the next 5 vehicles are from out of state? (Round to 4 decimal places )
Using combinations, we concluded that the probability that fewer than 2 of the next 5 vehicles are from out of state is 0.907.
A checkpoint sees 75% of its traffic coming from within the state.
Therefore, there is a 0.75 percent chance that the car comes from the state.
1-0.75=0.25 represents the likelihood that the car is from outside the state.
Let x now act as the random variable. Consequently, n=9 and X=4
