When you are trying to find the endpoint when given the midpoint and one point, what would the new formula be? Manipulate the formula using skills for solving literal equations. How would you find LaTeX: x_2\:\:\:or\:\:\:y_2x 2 o r y 2? Use LaTeX: x_m\:\:and\:\:\:\:y_mx m a n d y mto notate the midpoints. Remember the original midpoint formula is LaTeX: \left(\frac{x_1+\:x_2}{2},\:\:\frac{y_{1\:}+y_2}{2}\right)\:=\:\left(x_m,\:y_m\right)

Answer:
[tex](x_2,y_2) = (2x_m - x_1 ,2y_m - y_1 )[/tex]
Step-by-step explanation:
Given
[tex]\left(\frac{x_1+\:x_2}{2},\:\:\frac{y_{1\:}+y_2}{2}\right)\:=\:\left(x_m,\:y_m\right)[/tex]
Required
Determine x2, y2
Start by splitting the expression
[tex]x_m = \left(\frac{x_1+\:x_2}{2})[/tex] and [tex]y_m = (\frac{y_{1\:}+y_2}{2})[/tex]
Solving for x2 in [tex]x_m = \left(\frac{x_1+\:x_2}{2})[/tex]
Multiply through by 2
[tex]2 * x_m = \frac{x_1 + x_2}{2} * 2[/tex]
[tex]2x_m = x_1 + x_2[/tex]
Make x2 the subject;
[tex]x_2 = 2x_m - x_1[/tex]
Similarly:
[tex]y_m = (\frac{y_{1\:}+y_2}{2})[/tex]
Multiply through by 2
[tex]2 * y_m = \frac{y_1 + y_2}{2} * 2[/tex]
[tex]2y_m = y_1 + y_2[/tex]
Make y2 the subject;
[tex]y_2 = 2y_m - y_1[/tex]
Hence:
[tex](x_2,y_2) = (2x_m - x_1 ,2y_m - y_1 )[/tex]

Given: K is the midpoint of JL, M is the midpoint of LN
JK = MN
Prove: KL LM
Answers
Answer:
It's proved below
Step-by-step explanation:
We are given;
- K is the midpoint of JL
- M is the midpoint of LN
By definition of mid points, we can say that;
JK = KL and LM = MN
Now, we are given that JK = MN.
Thus, by substitution, we can deduce that; KL = LM
Thus is because JK can be replaced with KL and MN can be replaced with LM.
Thus, it is proved that KL = LM
Andre is buying snacks for the track and field team. He buys a pound's of apricots for $6 per pound and b pounds of dried bananas for $4 per pound he buys a total of 5 pounds of apricots and dried bananas and spends a total of $24.50 Which system of equations represents the constraints in the situation?
Answers
Answer:
a + b = 5 ...........1
6a + 4b = 24.50 ......... 2
Step-by-step explanation:
Let a be the amount of pounds of apricot bought
Let b be the amount of pounds of banana bought
If he buys a total pounds of 5 pounds then;
a + b = 5 ...........1
Also if a pound's of apricots for $6 per pound, total amount of aprciots bought will be $6a
Also if b pound's of banana is for $4 per pound, total amount of banana bought will be $4b
If he spends a total of $24.50 on both banana and apricots, then:
6a + 4b = 24.50 ......... 2
The system of equations that represents the constraints in the situation is:
a + b = 5 ...........1
6a + 4b = 24.50 ......... 2

[tex]\frac{-1}{8}[/tex]
Step-by-step explanation:
So first find the greatest common factor of the denominators
GCF of 2 , 4 and 8 is 8
Then :
[tex]\frac{-4 + 6 - 3}{8}[/tex]
So you do this to get the above answer:
8 divided by the denominator times the numerator.
You still need to work it out
-4 + 6 = 2
[tex]\frac{2- 3}{8}[/tex]
2 - 3 is -1
Thus the answer is [tex]\frac{-1}{8}[/tex]

The Beck family is planning on renting a car for their vacation. The two rental car companies have
different pricing plans.
Company A is $0.10 per mile and $25 a day.
Company B is $0.05 per mile and $40 a day.
Let x represent the number of miles and y represents the cost. They are only renting the van for 1 day.

Step-by-step explanation:
A: $0.1(x) + 25(y) = x + 25
B: $0.05(x) + $40(y) = x + 40

Answers
Answer:
B
Step-by-step explanation:
plug in 5
5^2-5(4)+7=12
===========================================
Work Shown:
A.
f(x) = 3x-8
f(5) = 3*5-8 ... replace every x with 5; simplify with PEMDAS
f(5) = 15-8
f(5) = 7
We can cross choice A off the list since we got 7 as an output, instead of 12.
---------------
B.
f(x) = x^2-4x+7
f(5) = (5)^2-4(5)+7
f(5) = 25-4(5)+7
f(5) = 25-20+7
f(5) = 5+7
f(5) = 12
We got the output we wanted. So we can stop here.
---------------
If you're curious about the others, then,
C.
f(x) = -x+14
f(5) = -5+14
f(5) = 9
That doesn't work, so we cross choice C off the list.
---------------
D.
f(x) = |x-7|
f(5) = |5-7|
f(5) = |-2|
f(5) = 2
Choice D is crossed out as well.
So only choice B works.

A survey found that women's heights are normally distributed with mean 62.6 in. And standard deviation 2.5 in. The survey also found that men's heights are normally distributed with mean 68.3 in. And standard deviation 3.3 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 57 in. And a maximum of 64 in. If the height requirements are changed to exclude only the tallest 50% of men and the shortest 5% of men, what are the new height requirements?
Answers
Answer:
The new height requirements are minimum of 64.1875 inches and maximum of 68.3 inches
Step-by-step explanation:
To exclude the tallest 50% of men and shortest 5% of men, we need to find the critical z-value for a significance level of 0.5 & 0.05 and then solve for x in the z-score equation.
For significance value of 0.5, z = 0
We are given;
μ = 68.3 in
σ = 2.5 in
Thus from z = (x - μ)/σ, we have;
0 =(x - 68. 3)/2.5
0 = x - 68. 3
x = 68.3 inches for men max
Similarly, for significance value of 0.05, z = -1.645
Thus to find x;
-1.645 = (x - 68. 3)/2.5
-4.1125 = x - 68.3
x = 68.3 - 4.1125
x = 64.1875 inches for men min
