The midpoint formula is as follows
[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Plug in the information we know.
[tex](1,-2)=(\frac{7+x_2}{2},\frac{2+y_2}{2})[/tex]
Solve for [tex]x[/tex]
[tex]1=\frac{7+x_2}{2}[/tex]
[tex]2=7+x_2[/tex]
[tex]x_2=-5[/tex]
Solve for [tex]y[/tex]
[tex]-2=\frac{2+y_2}{2}[/tex]
[tex]-4=2+y_2[/tex]
[tex]y_2=-6[/tex]
The other endpoint of the segment is [tex](-5,-6)[/tex]
Hope this helps.

which of the following statements does not represent the same value as the others
the absolute value of negative 9
the absolute value of 9
the distance between 0 and -9
the opposite of 9
Answer:
the opposite of 9
Step-by-step explanation:
the absolute value of nagative 9, is positive 9.
the absolute value of postive 9, is postive 9.
the distance between 0 and nagative 9 on a line would be a count of postive 9.
the opposite of postive 9 is negative 9 (the only one with a diffrent outcome)
find three consecutive integers for which 3 times the sum of the first and the third is -342
Answer:
The integers are -58, -57, -56.
Step-by-step explanation:
The difference between two consecutive integers is 1.
If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.
Integers: x, x + 1, x + 2
The sum of the first and third is: x + x + 2
3 times the sum of the first and third is: 3(x + x + 2)
That product equals -342.
3(x + x + 2) = -342
3(2x + 2) = -342
Divide both sides by 3.
2x + 2 = -114
Subtract 2 from both sides.
2x = -116
Divide both sides by 2.
x = -58
x + 1 = -57
x + 2 = -56
The integers are -58, -57, -56.

Answer:
The answer is B(s*12=96)
Is 4 to 7 the same as 7 to 4? explain why or why not
Answer:
Just say, "No, 7 to 4 is not the same as 4 to 7. I don't know why, but I just know because you taught me it wasn't."
Step-by-step explanation:
It worked for me lol
Answer:
4 to 7 is pretty much 4 divided by 7 which = 4/7 and 7/4 is 1 3/4. which is obviously greater. So they both equal different answers.

|-5| |-(-5) | Is this equal or which one is more ?
Answer:
Equal
Step-by-step explanation:
The absolute value of any number is the same as the value between the lines, but instead, it is positive. The lines (|x|)represent the amount of units/numbers |-5| and |-(-5)| is away from 0. They are both 5 numbers away from it, so it is equal.
Answer: Yes it is equal.
Step-by-step explanation:
when a number is an absolute, always assume it is possitive number.
Example: l-2l = 2 or l2l = 2

The sum of the measures of the angles shown is 90°.
(5x)
(7x + 6)
10. Write an equation to determine the value of x.
11. Find the value of x.
Answer:
10). 5x + (7x + 6) = 90
11). x = 7
Step-by-step explanation:
From the picture attached,
Sum of given angles measures 90°
Measures of the angles are (5x)° and (7x + 6)°
Therefore, equation to determine the values of x will be,
5x + (7x + 6) = 90
By combining similar terms of the equation,
12x + 6 = 90
12x = 90 - 6
12x = 84
x = [tex]\frac{84}{12}[/tex]
x = 7
Therefore, by solving the equation value of x will be 7.

Please help me choose if they are a yes or no.
Answer:
A)yes
B)yes
c)no
d)yes
e)yes
f)no
Part A
Answer: YesThis is the same as saying 2(AB+BC). A more written out version is AB+BC+CD+DA, though it's not needed since the opposite sides are congruent (AB = CD and BC = DA)
====================================================
Part B
Answer: YesThe diagonals of any parallelogram bisect each other. They cut each other in half.
====================================================
Part C
Answer: NoThe adjacent sides of a parallelogram aren't always equal in length. It only happens when we have a rhombus.
====================================================
Part D
Answer: YesThe angles mentioned are alternate interior angles. They are congruent due to AD and BC being parallel.
====================================================
Part E
Answer: YesWe can use the SSS or SAS congruence theorem to prove these triangles are congruent.
====================================================
Part F
Answer: NoThese are adjacent angles that aren't always the same measure. Diagonal AC does not bisect angle DAB. This only happens if we had a rhombus.

Three boys were running around the track. The first can run 1 lap in 15 min. The second can run 1 lap in 25 min. and the third can run a lap in 10 min. If the boys start running at 12:45, what time will all 3 boys pass each other again?
Answer:
At 15:15
Step-by-step explanation:
Given,
the 1st boy can run a lap in 15 minutes
the 2nd boy can run a lap in 25 minutes
the 3rd boy can run a lap in 10 minutes
Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.
[tex]L.C.M.[/tex] of 15,25 & 10 = 150
So,they will pass each other after 150 minutes or 2 hours & 30 minutes.
If we add it with 12:45 we'll get 15:15 or 3:15 pm

9514 1404 393
Answer:
a=2√2+4b = 3Step-by-step explanation:
√24 = 2√6
√48 = 4√3
Then the sum is ...
√24 +√48 = 2√6 +4√3
Factoring out √3, we have ...
= (2√2 +4)√3
Matching this to the form a√b, we have
(2√2+4)√3 ⇒ a=2√2+4, b = 3

what is the value of x (x+2)(x-3)=0
Answer:
x = 3 or x = -2
Step-by-step explanation:
Solve for x over the real numbers:
(x + 2) (x - 3) = 0
Hint: | Find the roots of each term in the product separately.
Split into two equations:
x - 3 = 0 or x + 2 = 0
Hint: | Look at the first equation: Solve for x.
Add 3 to both sides:
x = 3 or x + 2 = 0
Hint: | Look at the second equation: Solve for x.
Subtract 2 from both sides:
Answer: x = 3 or x = -2

In the diagram, what is the measure of WRS?
O 5°
O 7.5°
O 25°
O 37.5°
Answer : The measure of ∠WRS is 25°.
Step-by-step explanation :
As we know that vertically opposite angles are always equal.
In the given figure,
∠VRT = ∠WRS = (5x)° (Vertically opposite angles)
And we know that the sum of all angle in a straight line is equal to 180°.
So,
∠TSR + ∠WRS = 180°
Given: ∠TSR = (25x + 30)°
∠TSR + ∠WRS = 180°
(25x + 30)° + (5x)° = 180°
30x + 30° = 180°
30x = 180° - 30°
30x = 150°
x = 5°
∠WRS = (5x)° = (5 × 5)° = 25°
Therefore, the measure of ∠WRS is 25°.
Answer: 25°

For the function f(x) = −2(x + 3)2 − 1, identify the vertex, domain, and range.
Answer:
Vertex: (-3, -1)
Domain: All real numbers or (-∞, ∞)
Range: (-∞, -1]
Step-by-step explanation:
Quadratic Function: f(x) = a(bx - h)² + k
(h, k) is vertex
Step 1: Find vertex
f(x) = -2(x + 3)² - 1
h = -3
k = 1
Vertex = (-3, 1)
Step 2: Graph
When we graph, we should see our domain and range.
Domain is all x-values that can be inputted into the function.
Range is all y-values that can be outputted from the function.

Mikayla bought a bag of 84 pieces of candy and she wants to divide them up evenly and place into bags but doesn't won't more than 20 bags list the possible ways she can fill the bag
Answer:
[tex]1.0736 \times 10^{19}[/tex] ways
Step-by-step explanation:
Given that:
Mikayla bought a bag of 84 pieces of candy.
she wants to divide them evenly and place them into bag such that they are not more than 20 bags.
Therefore, the number of possible ways she can do that is ;
[tex]^{84}C__{20}[/tex]
= [tex]\dfrac{84!}{20!(84-20)!}[/tex]
= [tex]\dfrac{84!}{20!(64)!}[/tex]
[tex]= 1.0736 \times 10^{19}[/tex] ways
The possible ways she can fill the bag = [tex]1.0736 \times 10^{19}[/tex] ways
