By using the given diagram, we can see that the ordered pair that represents point B is (-4, 0)
Which ordered pair represents B?Any point on a coordinate plane has a ordered pair associated to it, that tells us the location of the point (x, y).
For example, the intersection between the two axes is the point (0, 0).
The first value, x, represents the horizontal displacement, the second variable, y, represents the vertical displacement.
Here we can see that B is 4 units to the left of the center, then the ordered pair that represents point B is (-4, 0)

Answers
Answer:
x = -2
Explanation:
The initial expression is:
10( x + 3) - ( -9x - 4) = x - 5 + 3
To solve for x, we first need to apply the distributive property as:
10x + 10(3) -(-9x) - (-4) = x - 5 + 3
10x + 30 + 9x + 4 = x - 5 + 3
Then, add the like terms to get:
(10x + 9x) + (30 + 4) = x + (-5 + 3)
19x + 34 = x - 2
Subtract x from both sides:
19x + 34 - x = x - 2 - x
18x + 34 = -2
Subtract 34 from both sides:
18x + 34 - 34 = -2 - 34
18x = -36
Finally, divide both sides by 18:
18x/18 = -36/18
x = -2
Therefore, the answer is x = -2

What is the area of a triangle?
The territory a triangle occupies inside its three sides or limits is known as its area. A triangle's sides determine its area. In essence, the length and base of the rectangle multiplied together with 0.5 gives the area of the triangle.
Mathematically, Area of a triangle = 0.5*height*base = 0.5*h*b -(ii)
r
Given, the length of the rectangle = l = 8 m
The breadth of the rectangle = b = 13 m
Area of the rectangle = 8*13 = 104 m² [Using (i)]
Also, the base of the triangle = b = 13 - 4 -4 = 5 m
The height of the rectangle = h = 6 m
Area of the triangle = 0.5*5*6 = 15 m²

None of the above
K = Y / X
Answers
The equation to find the constant of proportionality or k is K=Y/X.
The value of the ratio between two proportional quantities, known as the constant of proportionality, is constant. When the product or ratio of two changing amounts gives a constant, that relationship is said to be proportionate. Depending on the kind of proportion between the two specified quantities—direct variation or inverse variation—the proportionality constant's value will vary.
When two variables are proportional to one another either directly or indirectly, their relationship can be expressed as y = kx or y = k/x, where k specifies how the two variables are related to one another. This k is referred to as the proportionality constant.
Hence the equation to find the constant of proportionality or k is
K = Y/X

If you are dealt 4 cards from a shuffled deck of 52 cards, find the probability of getting two queens and two kings.
Answers
If you are dealt 4 cards from a shuffled deck of 52 cards, the probability of getting two queens and two kings is: 0.000133.
ProbabilityNumber of ways to get two of the four queens = 4C2 = 6 ways
Number of ways to get two of the four kings = 4C2 = 6 ways
Number of ways to get none of the deck = 48C0 = 1 way
Hence,
Number of ways to get four cards = 6 x 6 x 1
Number of ways to get four cards = 36 ways
Number of ways 4 cards can be chosen from 52 cards = 52C4 = 270725 ways
So,
Probability = 36 ways / 270725 ways
Probability = 0.0001329

Laura needs to buy chips and soda for the guests at her party. Each large bag of chips cost $2.40 and each large bottle of soda cost $2.00. She has $48.00 to spend. Part A Create an inequality using two variables to represent this situation. Be sure to explain the meaning of each variable.Part B Which of the following graphs represent the number of chips and soda bottles that Laura can buy? Part C Which combination of bottles of soda and bags of chips can Laura buy?
Answers
Part A.
To write the inequality we have to introduce variables that represent the things Laura needs to buy. For this reason let x be the number of sodas she buys and let y be the number of chips she buys.
Now, we know that each bag of chips cost $2.40 then tha ammount she spends in chips will be
[tex]2.4y[/tex]Following the same reasoning, the ammount she spends in sodas will be
[tex]2x[/tex]The total ammount she spends will be the sum of each ammount, that is:
[tex]2x+2.4y[/tex]Finally, we know that Laura has $48, so she can only spend less or equal this ammount.
Therefore the inequality representing this situation is
[tex]2x+2.4y\leq48[/tex]Part B.
To graph this inequality, first we have to graph the line given by
[tex]2x+2.4y=48[/tex]Doing this we obtained the following graph
Now we need to decide which semi plane represent the solution set of the inequality. Since we have a less or equal sign the right choice is the left one, then the graph of the inequality is
Therefore the graphs representing the number of chips and soda bottles Laura can buy is option B.
Part C.
To determine which combination of bottles of soda and chips Laura can buy we can graph the options we have. Remember that the x-axis represents the soda and the y-axis the chips. Hence the option we have will be equivalent to the points (4,24), (12,8), (16,8) and (28,4). Graphing this points we have
The only option allowed is the one that lies within the shaded region, therefore Laura can buy 12 bottles of soda and 8 bags of chips.
A car rental company charges $15 per day and $0.55 per kilometer to rent a car. What is the total bill if a car is rented for 4 days and is driven 146 kilometers? Andy how would I solve it
Answers
Answer:
$140.30
Step-by-step explanation:
The best way to solve this is to make an equation.
y = 15x + 0.55k
In simple terms this is:
Total = $15(number of days) + $0.55(Number of kilometers)
Plug in the values
15(4) + 0.55(146)
60 + 80.3
140.3
Since this is dollars it would $140.30!
Hope this explanation was good enough.
Answer: $140.30 is the total bill
Step-by-step explanation:
First, you would time 15 by 4 to get the price for the number of days you have rented the car. Which is $60
Now times $0.55 by 146 to get the price for the kilometers you have driven. Which is $80.30
Add both $60 and $80.30
The total bill is $140.30

The short line on the sides of the triangle tells us that those sides are equal.
We can see that LN = NJ and
LO = KO
This means that triangle LNO is similar to triangle triangle LJK
LO/NO = (LO + OK)/JK
Given that NO = 16 and JK = 6x + 8, it means that
LO/16 = (LO + OK)/(6x + 8)
Since LO = OK, it means that
LO + OK = LO + LO = 2LO
Therefore
LO/16 = 2LO/(6x + 8)By cross multiplying, it becomes
LO(6x + 8) = 2LO * 16
LO(6x + 8) = 32LO
Dividing both sides of the equation by LO, it becomes
6x + 8 = 32
6x = 32 - 8
6x = 24
