Step-by-step explanation:
Let the midpoint formula be expressed as;
M(X,Y) = {x2+x1/2, y2+y1/2}
X = x2+x1/2
Y = y2+y1/2
Get x2
-3 = x2 + 1/2
-6 = x2 + 1
x2 = -6-1
x2 = -7
Get y2;
Y = y2+y1/2
8 = y2+6/2
16 = y2+6
Y2 = 16-6
y2 = 10
hence the coordinate of B is (-7, 10). Option A is correct
I need serous help like now Marie can find the volume of a cube by using the formula V = s³, where s represents the side length of the cube. If Marie's cube has a side length of 2 1\2 centimeters, what is the volume of her cube? Show your work. Make sure that you include the correct unit of measure in your answer.
Answer:
[tex]V=15.62\ cm^3[/tex]
Step-by-step explanation:
The volume of a cube is given by the formula :
V = s³, where s represents the side length of the cube
The side length of Marie's cube is [tex]2\dfrac{1}{2}\ cm[/tex]. We need to find the volume of her cube. For this, we can use the formula of the volume of a cube such that,
[tex]V=(2\dfrac{1}{2})^3\\\\=(\dfrac{5}{2})^3\ cm^3\\\\=\dfrac{125}{8}\ cm^3\\\\=15.62\ cm^3[/tex]
So, the volume of her cube is [tex]15.62\ cm^3[/tex].
EFGH is a parallelogram. Find the given side length. Please help
Answer:
EF=35
EG=22
Step-by-step explanation:
EF
7y-14=2y+21
5y=35
y=7
EF=7(7)-14=49-14=35
EG
15x+7=12x+10
3x=3
x=1
EG=15(1)+7=15+7=22
Answer:
(a). 35 units ; (b). 44 units
Step-by-step explanation:
(a). 7y - 14 = 2y + 21 ⇒ y = 7
EF = 7(7) - 14 = 35 units
(b). EJ = JG
15x + 7 = 12x + 10 ⇒ x = 1
EG = 2 × (15(1) + 7) = 44 units

Please help me i don't understand. I will give points for explanation too.
Answer:
The first one
Step-by-step explanation:
4x - 3y = 15 .first you subtract the 4x from both sides to get it in correct form
-3y = -4x + 15 . Then you divide both sides by -3 to isolate the y
y = 4/3x - 5 . Then you are left with this answer
Answer:
y = 4/3x - 5 (first answer on your photo)
Step-by-step explanation:
4x - 3y = 15
4x - 3y = 15 (we use -4x)
-3y = 15 - 4x (divide by -3)
y = 4/3x - 5
Given ABC with AB=3,BC=5,and CA=6 find the length of a mid segment XY
Answer:
[tex] \overline{XY} = 1.5 [/tex]
Step-by-step explanation:
Given:
AB = 3
BC = 5
CA = 6
Required:
Length of XY
SOLUTION:
According to the Triangle Midsegment Conjecture, midsegment [tex] \overline{XY} [/tex] is half the length of [tex] \overline{AB} [/tex].
Therefore:
[tex] \overline{XY} = \frac{1}{2}(\overline{AB}) [/tex]
Thus:
[tex] \overline{XY} = \frac{1}{2}(3) [/tex]
[tex] \overline{XY} = \frac{3}{2} [/tex]
[tex] \overline{XY} = 1.5 [/tex]

Answer:
CB=18
And the measure of angle BDA is 21 degrees
Step-by-step explanation:
Answer: ∠BDA = 21; CB = 30
have:
sin ∠BDC = [tex]\frac{4x+6}{BD}[/tex]
sin ∠ADB = [tex]\frac{7x-12}{BD}[/tex]
because ∠BDC = ∠ADB => sin ∠BDC = sin ∠ADB
=> [tex]\frac{4x+6}{BD}=\frac{7x-12}{BD}[/tex]
=> 4x + 6 = 7x -12
<=> 3x = 18
<=> x = 6 => CB = 4.6 + 6 = 30

If ABCD is an isosceles trapezoid, what is the value of x?
AC = 5x - 25
BD = 3x + 11
Answer:
X=18
Step-by-step explanation:
Isosceles means two sides are equal. In this case AC and BD are the same. So put both equations equal to each other and solve
Answer:
the answer will be 18 it is correct answer
-12x+3y=24
1) y= -4x + 8
2) y= 4x - 8
3) y= 4x + 8
4) y = -4x -8
-12x+3y=24
(get y alone on the left)
3y=12x+24
(divide by 3)
y= 4x+8

what difficulty did you encounter in determining polynomials?
Answer:
I didn’t really encounter any difficulty in determining a polynomial. The issue was that numbers with negative exponents or those which had square roots in them aren’t referred to as polynomials.
The only minor issue was solving problems with numbers which had different exponents in them and needed some form of simplification.

The graph below represents a linear function
Wich of the following best represents the slope of the line shown below ?
Answer:
3/2
Step-by-step explanation:
rise over run....basically the slope goes 3 units up and 2 units to the right, and the slope is positive, so 3/2
what is the answer for this ?
Answer:
A
-2 < x ≤ 3 (All x values between -2 and 3; excluding -2 and including 3)
Step-by-step explanation:
I feel the answer is A because from what we know, domain is the x-intercept or x. So both C and D are not the answer because the y-intercept is not the domain, the y-intercept is the range. Next I looked at both A and B, well, if you look closely answer choice A says "excluding -2 and including 3" and choice B says "including -2 and excluding 3". I also seen on the graph that the point of (3,3) has a filled in dot and the point at (-2,-1) has an opened dot. A filled in dot always means you either have a ≥ (greater than or equal to sign) or a ≤ (less than or equal to sign). While an opened dot always means you just have < (greater than) or a > (less than) sign. So the correct answer is A!! Hope you have a fantastic rest of your day! :)))
simplify by using distributive property
3+11(2c+3)
Answer:
22c+36
Step-by-step explanation:
3+11(2c+3)
3+22c+33
3+33+22c
36+22c or 22c+26
Hey there!
In order to simplify this expression, all we have to do is distribute 11 by multiplying it times 2c and 3 and then combining like terms,
3+22c+33
As you can see, 3 and 33 are like terms; in order to simplify the expression, we should add them together.
36+22c
or
22c+36
Hope everything is clear.
Let me know if you have any questions!

Given the relation y = –4x2 – 8, if the input is 2, what is the output?
Answer:
y = -24
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
y = -4x² - 8
x = 2
Step 2: Solve
Substitute: y = -4(2)² - 8Evaluate: y = -4(4) - 8Multiply: y = -16 - 8Subtract: y = -24Answer:
Given, input (x) is 2,
[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]
