The steps shown can be used to prove that the medians of a triangle meet at a point.
Triangle A B C is shown on an x and y-axis. Lines are drawn from each point to the opposite side and intersect at point G. Point A is at (0, 0), point D is at (c, 0), point C is at (2 c, 0), point B is at (2 a, 2 b), and point E is at (a, b).
1. Define segments BD and CE as medians of triangle ABC.
2. Write linear equations for Line B D and Line C E.
3. Use a system of linear equations to solve for the coordinates of intersection point G.
4. Write the equation of Line A G.
5. Write an expression for the midpoint of BC, point F.

Solve the following: 5(2x+1)=50
Answer:
x = 9/2
Step-by-step explanation:
Answer:
x = [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
Given
5(2x + 1) = 50 ( divide both sides by 5 )
2x + 1 = 10 ( subtract 1 from both sides )
2x = 9 ( divide both sides by 2 )
x = [tex]\frac{9}{2}[/tex]
Raquela's coworker made price tags for several items that are to be marked down by 35%. Match each Regular Price to the correct Sale Price.
Regular Price: $4.19
Regular Price: $3.09
Regular Price: $3.77
Regular Price: $3.29
.: Sale Price: $2.01
.: Sale Price: $2.45
:: Sale Price: $2.72
: Sale Price: $2.14
9514 1404 393
Answer:
see below
Step-by-step explanation:
I like a spreadsheet for doing repetitive calculations. The matchup is shown in the attachment.
The sale price is 100% - 35% = 65% = 0.65 times the regular price.
__
Here, you can also identify the matches by putting the prices in numerical order. The lowest regular price will correspond to the lowest sale price.
regular, sale

Krystal is comparing two internet service plans . Plan 1 costs $134.97 every 3 months. If krystal plans to stay with one service plans for 1 year, which which choose? How much will she save?
Answer: See explanation
Step-by-step explanation:
Here's the correct question:
Krystal is comparing two internet service plans. Plan 1 cost $34.99 per month. Plan 2 costs $ 134.97 every 3 months. If Krystal plans to stay with one service plan for 1 year which should she choose? how much will she save?
Cost of plan 1 per month = $34.99 per month. Therefore, the cost for the year would be:
= 12 × $34.99
= $419.88
Plan 2 cost $134.97 for 3 months. Therefore the cost for the year would be:
= 4 × $134.97
= $539.88
She would choose the first plan as it's cheapee. She would also save:
= $539.88 - $419.88
= $120

Step-by-step explanation:
y = x - 4 and y = 4x + 2
=> x - 4 = 4x + 2
=> 3x = -6
=> x = -2
y = x - 4 = (-2) - 4 = -6
The solutions are x = -2 and y = -6.
Answer:
x = -2
y = -6
Step-by-step explanation:
y = x - 4
y = 4x + 2
y = y
then:
x-4 = 4x+2
x - 4x = 4 + 2
-3x = 6
x = 6/-3
x = -2
y = x - 4
y = -2 - 4
y = -6

if a+2b/3=2/c^9
what is 4/b
Answer:
[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]
Step-by-step explanation:
Given the expression
[tex]a+\frac{2b}{3}=\frac{2}{c^9}[/tex]
subtract a from both sides
[tex]a+\frac{2b}{3}-a=\frac{2}{c^9}-a[/tex]
Simplify
[tex]\frac{2b}{3}=\frac{2}{c^9}-a[/tex]
Multiply both sides by 3
[tex]\frac{3\cdot \:2b}{3}=3\cdot \frac{2}{c^9}-3a[/tex]
Simplify
[tex]2b=\frac{6}{c^9}-3a[/tex]
Divide both sides by 2
[tex]\frac{2b}{2}=\frac{\frac{6}{c^9}}{2}-\frac{3a}{2}[/tex]
Simplify
[tex]b=\frac{6-3ac^9}{2c^9}[/tex]
Calculating 4/b
[tex]\frac{4}{b}=\frac{4}{\frac{6-3ac^9}{2c^9}}[/tex] ∵ [tex]b=\frac{6-3ac^9}{2c^9}[/tex]
[tex]\frac{4}{b}\:=\frac{4\:\times \:\:2c^9}{6-3ac^9}[/tex]
[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]
Therefore, we conclude that:
[tex]\frac{4}{b}=\frac{8c^9}{6-3c^9a}[/tex]

Brian completed a 100 meter race in 11.74 seconds.Luis completed the race in 11.69 seconds.What was the difference between their times expressed as a fraction of a second?
Answer:
1 / 20
Step-by-step explanation:
Brian = 11.74 seconds
Luis = 11.69 seconds
Difference between their times :
11.74 - 11.69 = 0.05
Expressed as a fraction of a second :
0.05 / 1 = (0.05 * 100) / (1 * 100) = 5 /100 = 1/20

The data show the number of viewers for television stars with certain salaries. Find the regression equation, letting salary be the independent (x) variable. Find the best predicted number of viewers for a television star with a salary of $33 million. Is the result close to the actual number of viewers, 3.03.0 million? Use a significance level of 0.05.
Answer:
y = 5.064 - 0.010x
Here, in this question x = 33
y = 4.734 million views
In this question data is missing and I filled it out and calculated the questions accordingly. Please refer to the attachment for the data calculated.
Step-by-step explanation:
First of all, this question is incomplete. It lacks the data needed to calculate the required things.
So, I figured out the question and I will try my best to solve the question at hand.
I have calculated the some data sheet in excel. Please refer to the attachment for that data.
let a be the salaries
b be the viewers
[tex]S_{aa}[/tex] = ∑[tex]a^{2}[/tex] - [tex]\frac{ Summtion a^{2} }{n}[/tex]
[tex]S_{aa}[/tex] = 7522.8571
[tex]S_{bb}[/tex] = ∑[tex]b^{2}[/tex] - [tex]\frac{ Summtion b^{2} }{n}[/tex]
[tex]S_{bb}[/tex] = 47.1943
[tex]S_{ab}[/tex] = ∑[tex]ab^{}[/tex] - [tex]\frac{ Summtion a x Summation b^{} }{n}[/tex]
[tex]S_{ab}[/tex] = -76.8286
Now the slope of the required regression equation is:
Slope = [tex]S_{ab}[/tex]/[tex]S_{aa}[/tex] = -76.8286/7522.8571 = -0.010
And the intercept of the required regression equation:
intercept = [tex]\frac{1}{n}[/tex] x (∑b - slope x ∑a) = 5.064
So, the regression equation will be:
y = intercept + slope x
y = 5.064 - 0.010x
Here, in this question x = 33
y = 5.064 - 0.010 (33)
y = 4.734 million views

What is the solution to the system of equations graphed below?
y = 3x + 2
y = -2x - 3
Answer: x = -1; y = -1
y = 3x + 2
y = -2x - 3
⇔ y = 3x + 2
3x + 2 = -2x - 3
⇔ y = 3x + 2
5x = -5
⇔ y = 3x + 2
x = -1
⇔ y = -1
x = -1

Answer:
P+Q+R+S+T=540. then substitute x for result in p
Step-by-step explanation:
i would work it out but im lazy sorry
In a pentagon, there are 540 degrees
First, find x.
Set up the equation
132 + (4x+2) + 128 + (5x -11) + (4x - 10) = 540
Combine like terms
260 +13x -19 = 540
241 + 13x = 540
solve
13x = 299
x = 23
Now plug x in to angle p (4x + 2)
4(23) + 2
92 + 2 = 94
Therefore angle P = 94 degrees
Estimate the cost of painting the inner
wall of a well, if the depth of the well is
14 ft and the diameter is 8 ft. The cost of
painting 2.5 sq. ft is 20.
Answer:
2816 rupees
Step-by-step explanation:
here , depth = 14 ft
diameter = 8 feet
so , radius = 4 ft
We will paint it in its C.S.A.
C.S.A. of a cylindrical well
= 2πrh
= 2×(22/7)× 4 × 14
= 352 ft²
so,
cost = rate per unit area × area
= (20/2.5)×352
= 8×352
= 2816
so,the cost of the painting will be 2816 rupees

Screen-printing a batch of shirts requires 1 minute per shirt in addition to 4 minutes of initial set-up time. If it takes 41 minutes to screen-print a bath of shirts, how many shirts are in the batch?
Answer with the amount of shirts.
Answer:
There are 37 shirts in the batch.
Step-by-step explanation:
Since it takes an initial 4 minutes to set up the screen-printer, we can subtract 4 from 41 minutes to get the time used to print the shirts.
41 - 4 = 37
Since each shirt requires 1 minute of screen printing and there are 37 minutes, we can divide 37 by 1.
37 / 1 = 37
So there are 37 shirts in this batch. Hope this helps.
What are the coordinates of the point on the directed line segment from (-8, 5)(−8,5) to (4, -3)(4,−3) that partitions the segment into a ratio of 5 to 3?
Answer:
(2, -7/2)
Step-by-step explanation:
According to the midpoint theorem;
M(X, Y) = [(ax1+bx2/a+b), ay1+by2/a+b ]
(x1, y1) and (x2, y2) are the coordinates
a:b is the given ratio
Given the following
Coordinate of the line segment (-8, 5) and (4, -3)
Ratio: 5:3
Get the X coordinate;
X = ax1 + bx2 / a+b
X = 5(-8) + 3(4)/5+3
X = -40+12/8
X = -28/8
X = -7/2
Get the Y coordinate
Y = ay1 + by2 / a+b
Y = 5(5) + 3(-3)/5+3
Y = 25-9/8
Y = 16/8
Y = 2
Hence the required coordinate is (2, -7/2)
