An equation is considered linear if it is in the form of [tex]y = mx + c[/tex] where m is the slope of the equation and b is the y-intercept.
Notice how here, x can only be to the power of one. In here, the conditions are just simply m,c ∈ R.
Some examples include [tex]y = 8x + 9, 2y = x-7, 8y=0[/tex] and even some like [tex]x=4[/tex].
As you can see here, all of the following equations are represented using a straight line.
An equation is considered “non-linear” when it is not graphed using straight lines. Some examples include [tex]y = 3x^{2} +8, 4y =2x^{4}-6, y = x^{5} +86[/tex].
In conclusion, a linear equation will always be in the form of , where m is the slope of the equation, and b is the y-intercept of the equation.
Note: To determine if an equation is a linear function, it must have the form (in which m is the slope and b is the y-intercept). A nonlinear function will not match this form.
In a linear equation, the variables appear in first degree only and terms containing products of variables are absent. But in the case of nonlinear equations, at least one variable is not of the first degree or the equation contains a product of variables.
An equation is linear if its graph forms a straight line. This will happen when the highest power of x is . Graphically, if the equation gives you a straight line then it is a linear equation. Else if it gives you a circle, or parabola, or any other conic for that matter it is a quadratic or nonlinear equation.
If the highest power of x in the equation is one then it is a linear equation else if the power of x is greater than one then it is nonlinear.

We can determine if this equation is a linear function or a nonlinear function by looking at their graph.
What are linear functions and non-linear functions?
Simplify the equation as closely as possible to the form of y = ax + b.
On a Cartesian Plane, a linear function is a function where the graph is a straight line. The line can go in any direction, but it's always a straight line. The linear functions don't have any exponents higher than 1. Some of them don't have variables at all, and if they do, they have just plain x, which is equal to x to the first power. When a linear function is written in its simplest form, it looks like[tex]y = a + bx[/tex], where [tex]a[/tex] and [tex]b[/tex] are both constants. For example, here are some linear functions:
y = 3 + 5x
y = 2 - 6x
y = 4x
On a cartesian plane, a non-linear function is a function where the graph is never a straight line it is always curved may be a parabola, hyperbola or something else. Non-linear functions all have atleast one variable raised to the power of two or more. There's no one formula for non-linear functions because they're all different. For example, here are some non-linear functions:
y = 3x^3 + x^2 - 7
y = 5x^5 - 3x^2 +2
We can determine if this equation is a linear function or a nonlinear function by looking at their graph.

What is the factor of 3x² 7x 2?
The factors of the quadratic expression 3x² + 7x + 2 are 3x + 1 and x + 2.
We know for a quadratic expression of the form ax² + bx + c, the sum of the roots is -b/a and product of the root is c/a.
So in the given case
a = 3
b = 7
c = 2
Let the roots be α and β, therefore
α + β = -b/ a = -7/ 3
Also αβ = 2/3
We can find α and β by trial and error method. Else using the identity (a+b)² = a² + 2ab + b² and (a-b)² = a² - 2ab + b², we get
(a - b)² = (a + b)² - 4ab
Therefore
(α - β)² = (α + β)² - 4αβ
(α - β)² = (-7/ 3)² - 4×2/3
(α - β)² = 25/9
Assuming α>β,
α - β = 5/3
So solving α + β = -7/ 3 and α - β = 5/3, α = -1/ 3 and β = -6/3 = -2
Therefore simplifying
3x² + 7x + 2
= 3(x + 1/3)(x + 2)

Answer:
A. y = –0.2x + 2
Step-by-step explanation:
It is a negative slope and intersects at (0, 2).
Answer: A. y = –0.2x + 2
Step-by-step explanation:
We see that the answer options are in slope-intercept form, so we will find the slope and the y-intercept of this line to write our equation.
The line intercepts the y-axis at (0, 2), so the ending of our equation will be "+ 2" for the intercept.
Next, we will find the slope. We see that for everyone one unit moved downward, there is 5 units right. This becomes a slope of -1/5, which is the same as -0.2.
Using these details, the correct answer is;

What is compound interest?Compound interest is interest that is calculated on the original principal of a loan or deposit, as well as on any accumulated interest from previous periods.
What is the formula to calculate the compound interest?Compound interest is calculated using the following formula:
Compound interest = P * (1 + r/n)^(nt) - P
To calculate the total amount in the account after 2 years, we can use the following formula:
Total amount = P * (1 + r/n)^(nt)
In this formula, P is the principal amount (the initial deposit of $500), r is the annual interest rate (5.2%), n is the number of times that interest is compounded per year (12 in this case, since the interest is compounded monthly), and t is the number of years for which the interest is compounded (2 in this case).

Relation between base and height of parallelograms is a function [tex]f(x)=\frac{48}{x}[/tex].
What is a function?Relations called functions provide an output for each input. The characteristic that every input is associated to exactly one output defines a function as a relation between a set of inputs and a set of allowable outputs. A mapping from A to B will only be a function if every element in set A has one end and only one image in set B. Let A & B be any two non-empty sets.
Calculation:Based on the values listed in the table for the parallelograms' base length and height, you can see that the base length grows by one unit, giving you the numbers 1, 2, 3, and 4. When base length increases by one unit, height reduces by 1/x, as shown in the following example:

How can this be calculated?given the equation as 10x +5 = 100
then the equation can be rearranged as 10x = 100 - 5
this can be rearranged by substracting 5 from 100, which is

To Find the value of p:
We are told that the equation of the problem is y^2 = -4x
And the general formula is
y^2 = 4px
From there, we can deduce that
p = -1, because y^2 = 4(-1)x = -4x
This means that p = -1
To Find the focus:
To find the focus we can see the equations attached below for the focus, vertex, and directrix.
In these cases, the equations still apply, even though the variable is inverted, we just need to adjust it
y^2 = -4x
=>x = (-1/4)*y^2
x = a*y^2 + b*y +c
Focus: ((4ac -b^2 + 1)/4a, -b/2a)

-4x -4x
5y = -4x - 20
divide it all by 5
y = -4/5x - 4
Slope intercept form is y=mx+b. So you would first subtract 4x from both sides. This ends up being 5y= -4x +20. Then divide both sides by 5. This gets you y= (-4/5)x +4.

Dominic needs a new bike mirror his old mirror was a square with a side length of 9cm he wants the new mirror to have an area as close as possible to his old bike mirror
Answer choices 8cm 7cm 5cm
Answer:
If his old mirror had a side length of 9cm, that means the area would be 81cm (9 times 9)
For the circles:
A radius of 8: 201.06
A radius of 7: 153.94
A radius of 5: 78.54
The only one of these answers that is remotely close to dominics original mirror would be C: the radius of 5. 81 is close to 78.5!
How do you find the standard deviation of a sample given the mean and sample size?
Using the sample mean and the provided sample size, We can find the sample standard deviation by using the formula [tex]\sqrt \frac {\sum {(x-\bar x)^{2}}}{n-1}[/tex] .
What do you mean by sample?Sampling is the process of choosing a portion of a statistical population to estimate attributes of the entire population in statistics, quality control, and survey methods. Statisticians try to get samples that are typical of the population under consideration.
What is mean and standard deviation?The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a series of findings from a survey, experiment, or observational study.
The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
sample mean = [tex]\bar x[/tex]
sample size = n
sample standard deviation = [tex]\sqrt \frac {\sum {(x-\bar x)^{2}}}{n-1}[/tex]

How many real zeros does this graph have?
Answer:
3
Step-by-step explanation:
Real zeros are the times when the graph intercepts the x-axis or, in other words, when y = 0.
In this graph, the polynomial intercepts the horizontal (x) axis 3 times!
This means there are 3 real zeros.
