From the unique line postulate, we can draw unique line segment PM and as we are given that P is a point on the perpendicular bisector I of MN, the proof below has shown that using the definition of reflection, point P is the image of itself and point N is the image of point M
How to Interpret the Perpendicular Bisector?We are given :
Point P is a point on the perpendicular bisector, l, of MN.
Now, we want to prove that PM = PN
A Reflection in transformation can be defined as the transformation in which the figure is the mirror image of the other figure. This means that every point is a mirror reflection of itself .
With the aid of the definition of reflection, we can form the statement that point P is the image of itself , and point N is the image of M .
The line l which is the perpendicular bisector of MN acts as a Line of symmetry or axis of reflection.
Finally, when talking about transformations, it is common knowledge that reflections preserve length which means that the required proof PM = PN will hold true
Therefore, we will conclude that point N is the image of M .

1. Solve the inequality.
6x2 – x<2
Please show your work using methods learned in unit 1:
1) Factor
2)Discover the interval or intervals as learned in this unit.
3) Use a number line to graph.
4)State your answer in interval notation.
The solution of the inequality expression in interval notation is;
-1/2 < x < 2/3 and the number line is attached
How to solve the Inequality?We are given the Inequality expression as;
6x² - x < 2
To express the function in quadratic form, we subtract 2 from both sides to get;
6x² - x - 2 < 0
We now factorize this expression to get;
(2x +1)(3x - 2) < 0
This means that we have two inequalities solution which are expressed as; (2x + 1) < 0 and (3x - 2) < 0
For (2x + 1) < 0, add 1 to both sides to get;
2x < 1
divide both sides by 2 to get;
x < 1/2
Similarly, for (3x - 2) < 0;
Add 2 to both sides and then divide by 3 to get;
x < 3/2
Thus, the solution to the inequality is x = -1/2 and x = 3/2

You ask a deli clerk for x pounds of ham and x pounds of cheese. You end up getting 4 extra ounces of ham and
3 fewer ounces of cheese. The ham costs $6.24 per pound, and the cheese costs $4.80 per pound. You spend twice
as much on ham as you do on cheese. How much do you spend in total?
If the ham costs $6.24 per pound, and the cheese costs $4.80 per pound. You spend twice as much on ham as you do on cheese. The amount spent in total is: $187.20.
Total costLet number of ham bought = x + 4
Let number of cheese bought = x - 3
Price of ham = $6.24
Price of cheese = $4.80
Hence,
Amount spent on ham = (x+4)×6.24
Amount spent on ham =6.24x + 24.96
Amount spent on cheese = (x−3)×4.80
Amount spent on cheese =4.80x−14.40
So,
6.24 x + 24.96 = 2 (4.80 x - 14.40)
6.24x + 24.96 = 9.60 x - 28.80
Combine like terms
24.96 + 28.80 = 9.60 x - 6.24 x
3.36 x = 53.76
Divide both side by 3.36x
x = 53.76/3.36
= 16x
Now let find the total money spent where x is 16
Total amount = 6.24(16) + 24.96+ 4.80(16) - 14.40
Total amount = $187.20
Therefore the amount of $187.20 was spent in total.

An individual wants to bring multiple copies of two comic books to a convention this week. There are 15 copies of the comic book the individual wants to sell (S), and 8 copies of a comic book the individual wants appraised (A), with a combined weight of 49.9 oz. The individual can only fit 40 oz. of comics in a bag. If the individual brings 10 copies of the comic book he wants to sell (S), 4 copies to be appraised (A), the combined weight would be 30.2 oz. Calculate how much each comic (S) weighs.2.3 oz.2.25 oz.2.1 oz.
Let x represent the weight of the comic book to be sold
Let y represent the weight of the appraised book to be appraised
There are 15 copies of the comic book the individual wants to sell (S), and 8 copies of a comic book the individual wants appraised (A), with a combined weight of 49.9 oz. It means that
15x + 8y = 49.9 equation 1
If the individual brings 10 copies of the comic book he wants to sell (S), 4 copies to be appraised (A), the combined weight would be 30.2 oz, it means that
10x + 4y = 30.2 equation 2
Multiplying equation 2 by 2, it becomes
20x + 8y = 60.4 equation 3
Subtracting equation 3 from equation 1, it becomes
20x - 15x + 8y - 8y = 60.4 - 49.9
5x = 10.5
x = 10.5/5
x = 2.1
Substituting x = 2.1 into equation 2, it becomes
10(2.1) + 4y = 30.2
21 + 4y = 30.2
4y = 30.2 - 21 = 9.2
y = 9.2/4
y = 2.3
Weight of the comic(S) to be sold = 2.1 oz
The store manager put 7 belts in sale. The belts were originally $16. The manager marked down the price of the belts by 40% how much money did the store receive for selling all 7 belts
Original price: $16
Discount: 40%

16 x 40/100 = 16 x 0.4 = $6.4 ( discount amount)
Subtract the discount amount to the original price
16-6.4 = $9.6 new price

5(9.75) + d = 63.75; d = 15.00
The written and solved equation to determine the cost of the desserts, d is 5(9.75 + d) = 63.75; d = 3.00
How to write and solve equations?Five friends ate lunch and spent a total of $63.75.
They each bought the same meal for $9.75, and they each bought the same dessert.
The equation to determine the cost of the dessert, d can be represented as follows:
They are 5 friends,

5 (9.75 + d) = 63.75
48.75 + 5d = 63.75
Therefore, let's use the equation to solve for d.
48.75 + 5d = 63.75
63.75 - 48.75 = 5d

Suppose that the relation S is defined as follows.
s={(3, 0), (1, 2), (4, -1), (3, 9)}
Give the domain and range of S.
Write your answers using set notation.
The most appropriate choice for relation, domain and range will be given by-
Domain of S = {3, 1, 4}
Range of S = {0 , 2, -1, 9}
What is relation, domain and range?
A relation over set A and B is the subset of the cartesian product A x B.
Domain of a relation is the set of values for which the relation is defined.
Range is the set of solution obtained on putting the values of domain.
The relation S is defined as follows
S = {(3, 0), (1, 2), (4, -1), (3, 9)}
Now the set of values for which the relation is defined is the domain of the relation
For each ordered pair, the first number gives the values to be put in S. So the first number of every ordered pair is the domain.
So domain of S = {3, 1, 4}
Now, the second number gives the solution after putting the numbers in S.
So the second number of every ordered pair represents the range.
So, range of S = {0 , 2, -1, 9}

{(2,9), (2,-5),(-6,3), (4, -7)} this pair doesn't represent a function
A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none at all. The initial set or starting set is also called the domain; the final set or arrival set is called the rank.
Since in this set two elements of the range are associated with the same element of the domain [(2,9) and (2,-5)], we can conclude that it is not a function

The probabilities are (a) 0.4228, and (b) 0.8382
Define probability?
Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. The greater the likelihood of an occurrence, the more probable it will occur. Tossing a fair (unbiased) coin is a basic example. Because the coin is fair, the two possibilities ("heads" and "tails") are equally likely; the chance of "heads" equals the probability of "tails," and because no other outcomes are possible, the probability of either "heads" or "tails" is 1/2.
(a) probability of drawing first a white marble and then a red marble
= 4/(4+10+3) x 3(3+10+3) = 4/17 + 3/16 = 0.4228
(b) probability of drawing first a green marble and then a blue marble
