Given coordinates T(10,18) and the midpoint of segment ST at (5,-8), what are the coordinates of point S?
Answer:
S = (-4, -34)
Step-by-step explanation:
T=(10, 18) is one end of the segment
the midpoint is located at (5, -8)
therefore, using the formula for midpoint, we can find the other end of the segment (point S)
Midpoint x-value = xa + (xb - xa)/2
in our case;
5 = 10 + (xb-10)/2
3 - 10 = (xb-10)/2
-7 = (xb-10)/2
-14 = xb-10
xb = -14 + 10 = - 4
Now for the y value of the midpoint:
Midpoint y-value = ya + (yb - ya)/2
in our case:
-8 = 18 + (yb - 18)/2
- 26 = (yb - 18)/2
- 52 = yb - 18
yb = -52 + 18 = -34
Then. point S is located at: S = (-4, -34)
Answer: (0, -34)
Step-by-step explanation:
[tex]M(5,-8)=(\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2})\\(5,-8)(\frac{10 + x_{2} }{2} ,\frac{18 + y_{2} }{2})[/tex]
[tex]5=(\frac{10 +x_{2} }{2})\\ 10=10+x_{2} \\-10-10\\0 = x_{2}\\x_{2} =0[/tex] [tex]-8=(\frac{18 +y_{2} }{2})\\ -16=18+y_{2} \\-18-18\\-34 = y_{2}\\y_{2} =-34[/tex]
Coordinates of point S = (0, -34)

if <3 and <4 are vertical angles and m<3=9x+5 and m<4=5x+33 find <4
Answer:
68 degrees
Step-by-step explanation
If <3 and <4 are vertical angles, then <3 = <4
This means that
9x + 5 = 5x + 33
9x - 5x = 33 - 5
4x = 28
x = 28/4
x = 7
Since <4 = 5x+ 33
<4 = 5(7) + 33
<4 = 35 + 33
<4 = 68 degrees
Hence the measure of <4 is 68 degrees
please help me before i fail!! Find the solution(s) of the following equation.
c^2 = 144/169
Choose all answers that apply:
A) c = 12/13
B) c = -12/13
C) c = 14/15
D) c = -14/15
E) None of the above
Answer: A or B but really A
Step-by-step explanation:
c² = 144/169
√c² = √144/169
c = 12/13
or
-12/13² = 144/169
Hope that helped! I recommend choosing A
The solutions to the equation c² = 144/169 are c = 12/13 and c = -12/13, as they satisfy the equation when substituted into it. Thus, options A and B are the correct answers.
The equation is given as follows:
c² = 144/169
To find the solutions of the equation c² = 144/169, we can take the square root of both sides of the equation.
√(c² = ±√(144/169)
Since the square root of a number can be positive or negative, we have two possibilities for the solutions:
c = ±√(144/169)
Simplifying the square root of 144/169 gives:
c = ±(12/13)
So, the solutions to the equation are:
A) c = 12/13
B) c = -12/13
Therefore, options A and B are the correct answers.

Melissa makes and sells necklaces and bracelets. One day she made a total of 28 pieces of jewelry. On this day the number of bracelets crafted was 4 more than twice the number of necklaces.How many of each type of jewlery did she make that day
Answer:
Number of necklaces = 8
Number of bracelets = 20
Step-by-step explanation:
Given that:
Mellisa is making and selling the necklaces and bracelets.
Number of pieces of jewelry made on one day = 28
Number of bracelets was 4 more than the twice the number of necklaces.
To find:
Number of each type of jewelry made = ?
Solution:
Let number of bracelets = [tex]b[/tex]
Let number of necklaces = [tex]n[/tex]
As per question statement:
[tex]b+n=28[/tex] ...... (1)
[tex]b = 2n+4[/tex] ...... (2)
Putting the value of [tex]b[/tex] in equation (1):
[tex]2n+4+n=28\\\Rightarrow 3n = 28-4\\\Rightarrow 3n = 24\\\Rightarrow n =\bold{8}[/tex]
By equation (1):
[tex]b + 8 =28\\\Rightarrow b = \bold{20}[/tex]
So, the answer is:
Number of necklaces = 8
Number of bracelets = 20

Find the value of X and Y: 3x+9y=30 2(3x+9y)+x=64
pls help.
Answer:
x = 4 , y = 2
Step-by-step explanation:
3x+9y = 30 --------- (1)
2(3x+9y)+x = 64 ---------(2)
substitute (1) into (2)
2(30)+x = 64
60+x = 64
x = 64-60
x = 4
substitute x=4 into (1)
3x+9y = 30
3(4)+9y = 30
12+9y = 30
9y = 30-12
9y = 18
y = 18/9
y = 2
thus, x = 4 and y = 2

7 qt. of a 27% saline solution was mixed
with 3 qt. of a 17% saline solution. What
is the concentration of the mixture?
Answer:
24% saline
Step-by-step explanation:
Find how much saline is in both solutions:
7(0.27)
= 1.89
3(0.17)
= 0.51
Add this together:
1.89 + 0.51
= 2.4
Since there are 10 quarts in total, the concentration of the mixture can be found by dividing 2.4 by 10:
2.4/10
= 0.24
So, the concentration of the mixture is 24% saline
A circle has a radius of 4 x^3 y^5 cm. The area of a circle can be found using A equals pi r^2
What is the area of this circle in square centimeters?
Answer:
Step-by-step explanation:
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance. You can also think of the radius as the distance between the center of the circle and its edge.
This diagram shows the circumference, diameter, center, and radius on a circle.
how do i reflect over the y-axis if one point is over the y-axis?
Answer:
Coordinates of point B':
B' = (-1, -4)
Explanation
To reflect a point or a figure across the x-axis we use the rule:
→
In other words, we multiply the y-coordinate of our points by -1, while leaving the original x-coordinate as it is.
Let's apply the rule to every point of our triangle :
A = (2, 1)
A' = (2, 1*-1) = (2, -1)
B = (-1, 4)
B' = (-1, 4*-1) = (-1, -4)
C = (3, 7)
C' = (3, 7*-1) = (3, -7)

What is the x-value at which the graphs of y = x2 – 2x + 1 and y = x2 + 2x – 7 inter-
sect?
Answer:
x = 2
Step-by-step explanation:
Both equations are equal to y, so they're also equal to each other. We then set them equal to each other:
x^2 - 2x + 1 = x^2 + 2x - 7
We now do algebra to isolate x. Subtract 1 from both sides.
x^2 - 2x = x^2 + 2x - 8
Subtract 2x from both sides.
x^2 - 4x = x^2 - 8
Subtract x^2 from both sides.
-4x = -8
Divide both sides by -4.
x = 2

The Garcia family started the day with 222 gallons of milk. They drank 111 quart of milk for breakfast and 3 pints for lunch. How many pints of milk did the Garcia family have left after lunch?
Answer:
11 pints of milk the Garcia family have left after lunch.
Step-by-step explanation:
The Garcia family started the day with 2 gallons of milk.
They drank 1 quart of milk for breakfast and 3 pints for lunch.
Since, 1 gallon = 8 pint
2 gallon = 16 pint
and 1 quart = 2 pint
Left amount = 16 pint - ( 2pint + 3pint)
= 16-5
= 11 pints
Hence, 11 pints of milk the Garcia family have left after lunch.
