Solve the system of equations by graphing
Because the first equation is already solved for y we can substitute 3x−5 for y in the second equation and solve for x:
y=x−3 becomes:
3x−5=x−3
3x−5+5−x=x−3+5−x
3x−x−5+5=x−x−3+5
3x−1x−0=0+2
2x=2
2x/2=2/2
2x/2=1
x=1
Substitute
1 for x in the first equation and calculate y:
y=3x−5 becomes:
y=(3×1)−5
y=3−5
y=−2
The solution is x=1 and y=−2 or (1, -2)
What is graphical representation?Graphical representation refers to the use of intuitive charts to clearly visualize and simplify data sets. Data is ingested into graphical representation of data software and then represented by a variety of symbols, such as lines on a line chart, bars on a bar chart, or slices on a pie chart, from which users can gain greater insight than by numerical analysis alone. Representational graphics can quickly illustrate general behavior and highlight phenomenons, anomalies, and relationships between data points that may otherwise be overlooked, and may contribute to predictions and better, data-driven decisions. The types of representational graphics used will depend on the type of data being explored.To learn more about anomalies refer to:

Implicit Differentiation Homework Date Period Problems 1 - 8, Find Dy/Dx By Implicit Differentiation. 1. 8x^2 + Y^2 = 10
The solution to the implicit differentiation problem is dy/dx = -16x/2y.
To solve this problem, we must use implicit differentiation. This means that we must differentiate both sides of the equation with respect to the independent variable, x. We can do this by taking the derivative of both sides of the equation.
The derivative of 8x^2 is 16x and the derivative of y^2 is 2y dy/dx.
Therefore, the equation becomes: 16x + 2y dy/dx = 0
We can then solve for dy/dx by dividing both sides by 2y, which gives us dy/dx = -16x/2y.
Therefore, the solution to the implicit differentiation problem is dy/dx = -16x/2y.

Probability of being a senior or white
The probability of being a senior citizen and white is: (0.63)(0.3) = 0.189.
What is probability?Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty.
Given that the probability of identifying white is 0.63.
Then the probability of not white is:
1 - 0.63 = 0.37
Given that the probability of being a senior citizen is 0.3.
Then the probability of not a senior citizen is:
1-0.3 = 0.7
Hence, the probability of being a senior citizen and white is:
(0.63)(0.3) = 0.189

What are operations on functions?
Just like we add, subtract, multiply and divide the terms in a function, the functions can also be added, subtracted, multiplied or divided in a similar way.
Suppose there are two functions f(x) and g(x). The notations are as follows:
For Addition: (f+g)(x) = f(x) + g(x)For Subtraction: (f-g)(x) = f(x) - g(x)For Multiplication: (f×g)(x) = f(x) × g(x)For Division: (f/g)(x) = (f(x))/(g(x))Now, gof= g(f) = 3-f

Compared to lat yer, the population of Boom Town ha increaed by 25%. The population i now 6,000. What wa the population lat year
Compare to last year the population of the Boom town increased by 25% which is equal to 6000 then population of the last year is 4800.
As given in the question,
Present year population of the Boom town is equal to 6000
Let us consider 'y' be the population of Boom town last year.

⇒ y + (25/100)y = 6000
⇒ (100 + 25 / 100 )y = 6000
⇒ y = ( 600,000 / 125 )
⇒ y = 4,800 population of Boom town last.
Therefore, last year population of the Boom town is equal to 4,800.

The measures of the angle are a = 84°, b = 84°, c = 96°, d = 58°, e = 38° and f = 142°
How to determine the angle measures?
Angle geometry is a branch of mathematics that deals with the properties and relationships of angles in geometric figures.
Check the attached image for labeling
d = 180 - 122 = 58° (sum of angles on a straight line)
c = 96° (vertically opposite angles are equal)
a = 180 - 96 = 84° (sum of angles on a straight line)
b = a (vertically opposite angles are equal)
b = 84°
e = 180 - b -d (sum of angles in a triangle)
e = 180 - 84 - 58 = 38°
f = 180 - e (sum of angles on a straight line)

A collection of two or more inequalities in one or more variables is known as a system of inequalities.
What does it mean to solve a system of inequalities?Two or more inequalities in one or more variables make up a system of inequalities. When a problem calls for a variety of answers and those answers are constrained by multiple factors, systems of inequalities are used.
The intersection region of every solution in the system of inequalities is the system's solution.
Comparable to solving a system of linear equations, solving a system of linear inequalities involves locating the point (or points) of intersection, however this is not the case with inequalities. Instead, the area that fulfils each linear inequality will make up the solution set.
An inequality system's graph shows how the inequalities are resolved.

How do you dilate a linear equation?
Increasing or decreasing the size of a figure (referred to as the preimage) to produce a new figure is a type of transformation termed dilation. How much the dilation image will enlarge or reduce in size relative to the preimage is determined by the scale factor, r. Every time, k will have a value larger than 0.

What is linear equation ?
Linear equation can be defined as equation in which highest degree is one.
In order to determine the equation for this relationship, we need to first find the slope between these two values. There are two ways to do this:
1. Create a graph
*Create a graph with the x-axis representing the years past 2000 (so 2000 would be 0 and 2003 would be 3 and so on)
*Use the fact that slope=rise/run to get slope=2.7/3 (because we rise 87-84.3=2.7 and run 3 (from 2000 to 2003), and 2.7/3=27/30=9/10
*Plug this and the point (0, 84.3) into the formula y=mx+b to find the y-intercept of your equation
--> 84.3=(9/10)(0)+b --> b=84.3
So, your equation can be written now as y=(9/10)x+84.3
[Note: To check, if you plug in 3 you should get 87, and you do, so it works!]
2. Use the slope formula
Alternatively, you could have did slope=(y2-y1)/(x2-x1)=(87-84.3)/(3-0)=2.7/3=9/10
The process here would be the same as above
b) Here, just plug 10 into the equation above (since 10 is the number of years 2010 is after 2000, or 2010-2000=10). Doing this we get:
y=(9/10)(10)+84.3=9+84.3=93.3
So, in 2006 we have 93.3 people per sq mile
Therefore, In 2006 we have 93.3 people per sq mile .

How do you identify the base and exponent in an exponential notation?
We can identify the base and its exponent as the exponent indicates the number of times the base is used as a factor in an exponential notation.
What is Exponent ?An exponent is the number of times a number has been multiplied by itself. For instance, the phrase 2 to the third, which is represented as 23, means 2 x 2 x 2 = 8, not 23, and 2 x 3 = 6, respectively. Remember that every number multiplied by one is equal to itself.
Exponents are a technique of expressing extremely large numbers in terms of powers. The number of times a number has been multiplied by itself is the exponent, so to speak. For instance, the result of multiplying the number 6 by itself four times is 6 6 6 6. This can be expressed as 6⁴. Here, the exponent and base are 4 and 6, respectively.
An exponential number takes the shape of a, where an is multiplied by itself n times. The simple example is 8=23=222. In exponential notation, A is referred to as the base, whereas n is referred to as the power, exponent, or index. In scientific notation, 10, which is a specific illustration of exponential numbers, is typically always used as the base number.
Exponential notation make it easy to express powers succinctly. The exponent displays the base's multiplicative power. It can be written as 2 2 2 2=25 for the integer 32 because 2 is the "base" and 5 is the "exponent." The correct translation of this phrase is "two to the fifth power."
