Determine if triangle DEF with coordinates D(2,1), E(3,5), and F (6,2) is an equilateral triangle. Use evidence to support your claim
Answers
Answer:
No, it is isosceles.
Step-by-step explanation:
(In assumption that the points have been plotted on a graph)
After the points have been plotted we need to find the distance between each set of points. DE, DF, and, EF.
Finding DE and DF
To find DE and DF, we need to do some counting. From point D to point E, we travel 2 units right, and 8 units up forming an imaginary triangle with a right angle. From D to F, we again travel 8 units right and 2 units up, forming the same triangle, just oriented slightly differently.
Using the Pythagorean Theorem (\(a^2 + b^2 =c^2\)) we can plug in some values to find C and two of our side lengths.
\(a^2+b^2=c^2\)
\(2^2+8^2=c^2\)
\(4 + 64 = c^2\)
\(68=c^2\)
\(\sqrt{68} =c\)
\(8.25=c\)
The lengths of DE and DF are both roughly 8.25
Finding EF
Finding EF is going to be the same process but just a little different.
If we start at E and travel to F, we move down 6 units and right 6 units, forming another right triangle. now we use the Pythagorean Theorem (\(a^2 + b^2 =c^2\)) again, to find C and the length of EF.
\(a^2 + b^2 =c^2\)
\(6^2+6^2=c^2\)
\(36+36=c^2\)
\(72=c^2\)
\(\sqrt{72} =c\)
\(8.49=c\)
The length of EF is roughly 8.49 units.
Since not all of the sides of the triangle are the length, triangle DEF is not equilateral. Instead triangle DEF is isosceles.
Answer:
No it is isosoles

Tom is saving money to buy a game. So far he has saved $18, which is two-thirds of the total cost of the game. How much does the game cost?
Answers
To determine the total cost of the game, we can set up an equation based on the given information.
Let's assume the total cost of the game is represented by the variable "x."
According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:
(2/3) * x = $18
To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:
(3/2) * (2/3) * x = (3/2) * $18
x = $27
Therefore, the game costs $27.

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

For each function below, find its domain and then determine if the function increasing, decreasing, or constant on each piece of the domain. Sometimes the domain is just one interval, but the function still changes its behavior at some points. s(t)=\(\frac{-5}{|t|}\)
The interval on which the function is decreasing is : ( , )
The interval on which the function is increasing is : ( , )
The interval on which the function is constant is : ( , )
Leave unused fields blank.
Answers
Answer and explanation:
First, the domain is all real numbers except 0, since x = 0 is the asymptote.
D: x ∊ R, x ≠ 0
or
D: (-∞, 0) ∪ (0, ∞)
The range is everything below y = 0.
R: y < 0
or
R: (0, -∞)
Next, this function is never constant so there are only intervals of increasing and decreasing. The intervals meet at x = 0.
inc: x > 0
dec: x < 9
or
inc: (0, ∞)

Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A
Find the m∠RLU. A. 20 B. 42 C. 84 D. 10
Answers
Answer:
b is the correct answer. p is 10
The value of m∠RLU = 10.
How to estimate the value of m∠RLU?Given: (5p - 8) and (2p + 22)
Simplifying both of the equation, then we get
5p - 8 = 2p + 22
Add 8 to both sides of the equation, then we get
5p - 8 + 8 = 2p + 22 + 8
simplify
5p = 2p + 30
substract 2p from both sides of the equation
5p - 2p = 2p + 30 - 2p
3p = 30
p = 30/3
p = 10.
m∠RLU = 10
Therefore, the correct answer is option D. 10.

1. In the first problem, we need to subtract 1 from 9 since there is an addition:
9 – 1 = 8
Next, divide 8 by 2, and we get:
8 ÷ 2 = 4
This means that x = 4
Finally, check the answer by:
2(4) + 1 = 9
2. In the second problem, we need to subtract 3 from 19 since there is an addition:
19 – 3 = 16
Next, divide 16 by 4, and we get:
16 ÷ 4 = 4
This means that x = 4
Finally, check the answer by:
4(4) + 3 = 19
3. In the third problem, we need to add 2 with 7 since there is subtraction:
2 + 7 = 9
Next, divide 9 by 3, and we get:
9 ÷ 3 = 3

Finally, check the answer by:
3(3) – 2 = 7

You want to know if the relation shown is a function.
FunctionA set of ordered pairs (x, y) represents a function if there are no repeated x-values. Here, there are 4 unique x-values for the 4 ordered pairs (none are repeated), so this relation is a function.

Additional comment
Yes, it's that simple.
Look down the x-list. If you see any repeats, it is not a function. The same is true for ordered pairs (x, y). If there are any repeated first numbers, it is not a function.
