Answer: C. x=-8,14
Step-by-step explanation:
C
Answer:
x = 14, –8Step-by-step explanation:
|x – 3| = 11
(x - 3) = 11 - (x - 3) = 11
x - 3 = 11 - x + 3 = 11
x = 11 + 3 -x = 11 - 3
x = 14 -x = 8
x = -8

K ( -3, 7 ), and L ( 8, 7 what is the slope?
Eliminate the y in the following system of equations. What is the result when you add the two equations?
x+y=2
3x-4y=27
A.7x=29
B.x=-23
C.7x=35
D.4x=29
Answer:
C
Step-by-step explanation:
x + y = 2
Subtract x from both sides;
y = -x + 2
3x - 4y = 27
Substitute y;
3x - 4(-x + 2) = 27
Distribute;
3x + 4x - 8 = 27
7x - 8 = 27
Add 8 to both sides;
7x = 35
Divide both sides by 7;
x = 5

the midpoint of ab is m (3,-4). If the coordinates of A are (8,-5), what are the coordinates of B
Answer:
work is attached and shown
The coordinates of the midpoint will be (-2,-3).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
A midpoint is a point that lies on a line connecting two other locations and is in the middle of the line. Given that the midpoint of AB is M(3,-4) and the coordinates of A are (8, -5).
The midpoint will be calculated by using the formula below:-
( 8 + x ) / 2 = 3
( 8 + x ) = 6
x = -8 + 6 = -2
( -5 + y ) / 2 = -4
( -5 + y ) = -8
y = -8 + 5 = -3
Therefore, the coordinates of the midpoint will be (-2,-3).

How do u write 0.57 repeating as a fraction in simplest form explain the steps please!
Answer:
57/99
Step-by-step explanation:
let's set up an equation:
x = 0.5757...
set up a second equation so the numbers after the decimal places are equal
100x = 57.5757...
subtract
100x = 57.5757...
- x = 0.5757
99x = 57
divide by 99
x = 57/99
0.57 repeating can be expressed as the fraction 19/33 in simplest form.
We have,
Let x = 0.575757... (with 57 repeatings)
Multiplying x by 100,
100x = 57.575757...
Subtracting the original x from 100x,
100x - x = 57.575757... - 0.575757...
99x = 57
To obtain x, divide both sides by 99:
x = 57/99
Dividing both the numerator and denominator by 3,
x = (57/3) / (99/3)
x = 19/33
Therefore,
0.57 repeating can be expressed as the fraction 19/33 in simplest form.

What’s the answer too this problem?
Think about the rule when multiplying powers together.
When multiplying two powers that have the
same base, simply add their exponents.
In this problem, each power has a base
of a and our exponents are m and n.
So adding these exponents together, we have a^m + n.

Richard buys a new car for $28,000. The car depreciates in value by 9% each year. Write an expression model to represent this situation. Use the variable y to represent the value of the car after t years.
Given :
Worth of new car , C = $28000 .
Depreciates in value of car , D = 9 % .
To Find :
Use the variable y to represent the value of the car after t years.
Solution :
Depreciation formula is given by :
[tex]y=C(1-\dfrac{D}{100})^t[/tex]
Putting all given values , we get :
[tex]y=C(1-\dfrac{D}{100})^t\\\\y=28000\times (1-\dfrac{9}{100})^t\\\\y=28000( \dfrac{91}{100})^t[/tex]
Therefore , the required equation is [tex]y=28000( \dfrac{91}{100})^t[/tex] .
Hence , this is the required solution .

Use the figure and find PT.
PT = 7x - 24 and TQ = 6x-2
Answer:
PT= 130
Step-by-step explanation:
Since T is the midpoint of segment PQ,
PT = TQ
7x - 24 = 6x-2
Subtract 6x both sides and add 24 both sides
7x -6x - 24 = 6x -6x -2
x - 24 + 24 = -2 + 24
x= 22
Substitue x into PT
7(22) - 24
154 - 24
PT= 130
what is the equation of the line parallel to the line y=1/4x+5 and passing through the point (2,-1)
Answer:
The answer is
[tex]y = \frac{1}{4} x + \frac{1}{2} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The equation of the line is
y = 1/4x + 5
Comparing with the general equation above
Slope / m = 1/4
Since the lines are parallel their slope are also the same
Slope of parallel line = 1/4
So the equation of the line using point (2,-1) and slope 1/4 is
[tex]y + 1 = \frac{1}{4} (x - 2) \\ y - 1 = \frac{1}{4} x - \frac{1}{2} \\ y = \frac{1}{4} x - \frac{1}{2} + 1[/tex]
We have the final answer as
[tex]y = \frac{1}{4} x + \frac{1}{2} [/tex]

If the original rectangle has an area of 2 cm squared and the scaled copied has an area of 50 cm squared what is the scale factor used to draw the scaled copy
Answer:
The scale factor used to draw the scaled copy is a factor of 5
Step-by-step explanation:
Here, we are interested in calculating the scale factor which was used to transition the original rectangle to the new scaled copy.
Firstly, there is a way to relate how the scale factor of the sides relate to the scale factor of the area. What we are saying here is that the scale factor of the sides is never equal to that of the area;
For a 2 cm^2 area let’s say the sides are 1 by 2 ; this gives us an area as said
Now, to get 50cm^2, we can see that the scale factor of both areas is 25 (2 to 50)
So the area has been scaled 25 times the original area. So how has the sides been scaled?
Using a general principle, the scale used to scale the area is the square of the scale used to scale the sides. What are we saying here? if the area is scaled by 4, then the sides are scaled by 2
So in this particular case, the area is scaled by a factor of 25
Now, the scale factor of the sides will be the positive square root of this which is 5
Hence, we can conclude that the sides of the smaller triangles were each multiplied by 5 to arrive at the sides of the bigger one which makes it that the scale factor used to draw the scaled copy is 5
