The midpoint of line segment AB is (1,2). if the coordinates of A are (1,0) what are the coordinates of B
The required coordinate of B will be at (1, 4)
When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;
[tex]M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ][/tex] where:
[tex]X =\frac{x_2+x_1}{2} \\Y=\frac{y_2+y_1}{2}[/tex]
From the question, we are given the following coordinate points
[tex]X=1\\x_1=1\\[/tex]
Get x₂;
[tex]X =\frac{x_2+x_1}{2}\\1 =\frac{x_2+1}{2}\\2=x_2+1\\x_2=2-1\\x_2=1\\[/tex]
Get y₂;
[tex]Y =\frac{y_2+y_1}{2}\\2 =\frac{y_2+0}{2}\\2 \times 2=y_2+0\\4=y_2+0\\y_2=4\\[/tex]
Hence the coordinate of B will be (1, 4)

Valeria purchases a can of chicken noodle soup and a can of tomato soup. The can of chicken noodle soup has a height of 4 inches and a radius of 2 inches. What is the volume of the can of chicken noodle soup?
Use ≈3.14 and round your answer to the nearest whole number.
The can of tomato soup has the same volume, but a radius of 2.5 inches. What is the height of the can of tomato soup?
Use ≈3.14 and round your answer to the nearest tenth.
Questions
Answer:
The height of the tomato soup can is 2.6 in.
Step-by-step explanation:
"The can of chicken noodle soup has a height of 4 inches and a radius of 2 inches."
We can find the volume of this can.
V = pi r² h
V = 3.14 * (2 in.)² * (4 in.)
V = 50.24 in.³
"The can of tomato soup has the same volume, but a radius of 2.5 inches."
Now we know the volume of the can, so we can find the height, h.
V = pi r² h
50.24 in.³ = 3.14 * (2.5 in.)² * h
50.24 in.³ = 19.625 in.² * h
h = (50.24 in.³)/(19.625 in.²)
h = 2.56 in.
Answer: The height of the tomato soup can is 2.6 in.
Answer:
:Volume of can of chicken noodle soup=50.24inch^3
:Height of can of tomato soup=2.56inches
Step-by-step explanation:
CHICKEN NOODLE SOUP :height=4inches
:radius=2inches
[ V=πr2h]
V=(3.14×2×2×4)=50.14
Now, Volume is same of both the can.
Volume of can of tomato soup=50.24;radius=2.5inches;
Height of can of tomato soup,
50.24=(3.14×2.5×2.5×h)
50.24=19.625h
h=50.24/19.625
=2.56inches

Step-by-step explanation:
Triangles ABC and XYZ are similar. Find side x.
Answer:
x=6
Step-by-step explanation:
side AB is proportional to side XY
side AC is proportional to side XZ
Since we know side AB and side XY are proportional to each other, if we divide side AB by side XY, we can find the size difference...
12 / 4 = 3
The smaller triangle is 3 times smaller than the bigger triangle so we can find side XZ by dividing side AC by 3...
18 / 3 = 6
x = 6
The measure of the length of x is 9 units.
What are similar triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "≈".
Given triangles ABC ≈ XYZ
for similar triangles, corresponding sides are proportionately equal and corresponding angles are congruent,
so AB/XY = AC/XZ = BC/YZ
substitute the values
12/4 = 18/x = 9/YZ
12/4 = 18/x
x= 9 units
Hence the value of x is 9 units.

The midpoint of a sègment is (6,-4) and one endpoint is (13,-2). Find the coordinates of the other endpoint.
let other one be (x,y)
We know midpoint formula
[tex]\boxed{\sf (x,y)=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}[/tex]
[tex]\\ \sf\longmapsto (6,-4)=\left(\dfrac{13+x}{2},\dfrac{-2+y}{2}\right)[/tex]
[tex]\\ \sf\longmapsto \dfrac{13+x}{2}=6[/tex]
[tex]\\ \sf\longmapsto 13+x=12[/tex]
[tex]\\ \sf\longmapsto x=12-13[/tex]
[tex]\\ \sf\longmapsto x=-1[/tex]
And
[tex]\\ \sf\longmapsto \dfrac{-2+y}{2}=-4[/tex]
[tex]\\ \sf\longmapsto -2+y=-8[/tex]
[tex]\\ \sf\longmapsto y=-8+2[/tex]
[tex]\\ \sf\longmapsto y=-6[/tex]
Answer:
(- 1, - 6 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ) ← midpoint formula
Use this formula on the endpoints and equate to the coordinates of the midpoint.
let the other endpoint = (x, y) , then
[tex]\frac{13+x}{2}[/tex] = 6 ( multiply both sides by 2 )
13 + x = 12 ( subtract 13 from both sides )
x = - 1
[tex]\frac{-2+y}{2}[/tex] = - 4 ( multiply both sides by 2 )
- 2 + y = - 8 ( add 2 to both sides )
y = - 6
The coordinates of the other endpoint are (- 1, - 6 )
A parabola has x-intercepts at x=-3 and x=4. What the equation of the parabola?
Answer:
x² - x - 12 = 0
Step-by-step explanation:
Given the x- intercepts are x = - 3 and x = 4 , then the factors are
(x + 3) and (x - 4)
Expressing as a zero product
(x + 3)(x - 4) = 0 ← expand using FOIL

The mean (average) weight of three boys is 40 pounds. One of the boys weighs 50 pounds. The other two boys have the same weight. Find weight of each of the boys?
Answer:
The weights are 50 lb, 35 lb, and 35 lb.
Step-by-step explanation:
The three boys weight x, y, and z pounds.
One boy weighs 50 lb, so x = 50. The other 2 boys have the same weight, so y = z.
The average weight is the sum of the three weights divided by 3.
(x + y + z)/3 = 40
(50 + y + y)/3 = 40
2y + 50 = 120
2y = 70
y = 35
z = y = 35
Answer: The weights are 50 lb, 35 lb, and 35 lb.
Answer: 35 lb, 35 lb, and 40 lb
Step-by-step explanation:
(50+X+X)/3 = 40
50 + 2X = (40)(3)
2X = 120 - 50
X = 70/2
X = 35

d. the quantity two times x plus two all over two equals ten over two; Division Property of Equality
Answer: x = 4
Step-by-step explanation:
2(x+1)=10
Distributive properties
a*(b+c)=(a*b)+(a*c)
Using distributive properties
Then
2*(x+1)=(2*x)+(2*1)
2*(x+1)=2x+2
Now, commutative properties
a*b=b*a
Addition is cumulative
a+(-b)=(-b)+a
Therefore applying to 2x+2
2x+2+(-2)=2x+(-2)+2
Then, applying to the equation
2x+2+(-2)=10+(-2), +×-=-
2x+2 -2=10-2
2x=8
Using division properties
ax=b
If a is none zero
Then ax/a=b/a
Therefore x=b/a
Applying that to 2x=8
2x=8. Divide both side by 2 which is none zero

The graph of a linear relation passes through the point (-2,7) and has a slope of 1/6.
Determine an equation for this linear relation in slope intercept form.
Answer:
Step-by-step explanation:
eq. of any line withslope 1/6 is
y=1/6x+c
∵ it passes through (-2,7)
so 7=1/6(-2)+c
c=7+1/3=22/3
eq. of line is
y=1/6x+22/3
Answer:
y = 1/6x + 7 1/3
Step-by-step explanation:
Slope intercept form is y=mx+b where m is the slope and b is the y intercept
y = 1/6x+b
Substitute the point into the equation
7 = 1/6(-2)+b
7 = -1/3+b
Add 1/3 to each side
7 1/3 = b
y = 1/6x + 7 1/3

C.
x = 3
D.
x = -18
Answer:
D: x = -18
Step-by-step explanation:
A good way to solve this it to input all options until you find the one that fits for both options.
Option A :
15 + 6 / 15 - 3 = 21 / 12 or 7/4
So this one doesn't work.
Option B :
10 + 6 / 10 - 3 = 16 / 7
So this one also doesn't work.
Option C:
3 + 6 / 3 - 3 = 9 / 0 which is 0 by the laws of dividing by zero.
This one also doesn't work leaving only one option.
Option D:
-18 + 6 / -18 - 3 = -12 / -21 or 4 / 7
And by solving we can find out we did our work correctly and get our answer.
