What is the measure of \angle A in the triangle above?
Answer:
m<A = 62
Step-by-step explanation:
180 - 116 = 64
3x - 13 + 2x + 4 + 64 = 180
5x + 55 = 180
5x = 125
x = 25
<A:
3x - 13
3(25) - 13

In the form of a paragraph, use complete sentences to describe some of your observations that helped you to conclude who researched textbook prices. Use specific examples from the data, histograms and box and whisker plots.
Answer:
It was most likely Tyler who researched it as his range of books is much larger than that of Felix.
Step-by-step explanation:
From the bar graph to the box and whisker plot, the right is always the one with more variety just as in the first plot that was shown.

sara compares to phone plans. plan A charges $99 for the phone plus $25 per month. plan B charges $39 for a phone and a $35 per month. at what month will the plans cost the same?
Answer: 6th month
Step-by-step explanation:
Let the month where the plans cost the same be represented by x.
Plan A charges $99 for the phone plus $25 per month. This can be written as:
= 99 + 25x
Plan B charges $39 for a phone and a $35 per month. This can be written as:
= 39 + 35x
We then equate both equations and this will be:
99 + 25x = 39 + 35x
Collect like terms
99 - 39 = 35x - 25x
60 = 10x
x = 60/10
x = 6
The plan will cost the same in the 6th month.
Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
[tex]x = 25[/tex]
Step-by-step explanation:
The angles are vertical since they form from two lines crossing at a point and they share a same vertex.
Vertical angles are equal so
[tex]4x - 25 = 75[/tex]
[tex]4x = 100[/tex]
[tex]x = 25[/tex]

help! i just need the answers. maybe some explanations would be good too :)
For Number one: -xy + 2x = 20, x = 5
To solve this, all we need to do is plugin 5 for every place we have x. So...
- (5)y + 2(5) = 20
-5y + 10 = 20
-5y = 10
y = -2
For number two: 4x - 3y - 10 = 1, x = -1
To solve this, we need to plugin -1 for all of the x variables. So...
4 (-1) - 3y - 10 = 1
-4 - 3y - 10 = 1
-14 - 3y = 1
-3y = 15
y = -5
For number three: 5x + 7y = -1, x = 4
We need to plugin -4 for all of the x variables. So...
5 (4) + 7y = -1
20 + 7y = -1
7y = -21
y = -3
For number four: x = 6 + xy, x = -3
Same as the other ones, just plugin -3 for all of the x variables. So...
-3 = 6 + (-3)y
-3 = 6 - 3y
-9 = -3y
3 = y
I hope this helps :)

Answer:
AE = 9 units
Step-by-step explanation:
Based on the centroid theorem:
AX = ⅔ of AE
Given that AX = 6 units, where X is the centroid of ∆ABC, therefore:
6 = ⅔ of AE
6 = ⅔(AE)
Multiply both sides by 3
6*3 = ⅔(AE)*3
18 = 2(AE)
Divide both sides by 2
18/2 = AE
9 = AE
AE = 9 units

Answer:
x = 12 cm
Step-by-step explanation:
Based on the tangent and secant theorem,
8² = 4(4 + x)
Solve for x
64 = 16 + 4x
Subtract 16 from both sides
64 - 16 = 4x
48 = 4x
Divide both sides by 4
48/4 = 4x/4
12 = x
x = 12
factorise completely:
1. 3xy - x
2. 4a² - 9
Answer:
x(3y - 1) and (2a - 3)(2a + 3)
Step-by-step explanation:
(1)
3xy - x ← factor out x from each term
= x(3y - 1)
(2)
4a² - 9 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4a² - 9
= (2a)² - 3²
= (2a - 3)(2a + 3)

What is a Scatter Plot?Dots are used in a scatter plot to show the values of two different numerical variables. Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.
The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger the relationship. If the data points make a straight line going from near the origin out to high y-values, the variables are said to have a positive correlation.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
Given data ,
Let the scatter plot represents the funds raised by a TV station since its first year of operations
Let the number of years be represented as x
Let the contribution be represented as y
where the values of x and y are
x = { 1 , 3 , 5 , 8 , 11 , 14 }
y = { 70000 , 150000 , 190000 , 230000 , 270000 , 290000 }
The scatter plot is graphed and the linear regression equation is
y = 15901.6x + 88688.5

Answer:

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Latanya sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
58 visitors purchased no costume.
156 visitors purchased exactly one costume.
23 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase exactly one costume as a fraction in simplest form.
Answer:
52/79
Step-by-step explanation:
One costume = 156 (This is our numerator.)
All visitors = 156 + 58 + 23 = 237 (This is our denominator.)
156/237
Find the GCF to simplify (sneak peek it's 3)
