The coordinates of point J are (5, −6) and the coordinates of the point K are (7, 8).
What are the coordinates of the point one half the distance from J to K?
Answer:
The coordinates of the point one half the distance is (6,1)
Step-by-step explanation:
Here we want to calculate the coordinates one half of the line segment.
This in another way simply means the coordinates of the midpoint of that segment;
Mathematically;
we proceed with this using the midpoint formula
(x,y) = (x1 + x2)/2, (y1 + y2)/2
From the question (x1,y1) = (5,-6) while (x2,y2) = (7,8)
let’s say
(x,y) = (5 + 7)/2 , (-6 + 8)/2
(x,y) = 12/2, 2/2
(x,y) = (6,1)
If the line px -5y = 60 has a slope of -23 then p equals ....
Answer:
p = - 115
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
px - 5y = 60 ( subtract px from both sides )
- 5y = - px + 60 ( divide all terms by - 5 )
y = [tex]\frac{1}{5}[/tex] px - 12 ← in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex] p , thus
[tex]\frac{1}{5}[/tex] p = - 23 ( multiply both sides by 5 to clear the fraction )
p = - 115

|x-1|+5=2 also this question
Answer:
No solution
Step-by-step explanation:
There are no values of x that make the equation true.
Answer: No solutions
==========================================
Explanation:
Start things off by subtracting 5 from both sides
|x-1|+5 = 2
|x-1|+5-5 = 2-5
|x-1| = -3
We cannot go any further after this point. The result of any absolute value is never negative. The absolute value represents distance from some number to 0. For example, saying |-7| = 7 means -7 is seven units away from 0 on a number line. Negative distance does not make sense.
So going back to |x-1| = -3 makes no sense as well. There are no numbers we can plug in for x to have |x-1| = -3 be true.
The equation |x-1| = -3 has no solutions, so the original equation doesn't have any solutions either.

Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.
15 yd
Syd
8 yd
11 yd
6 yd
?
Answer:
7 yd
Step-by-step explanation:
The sum of horizontal measures is the same across the top and bottom:
15 yd = 8 yd + ?
7 yd = ? . . . . . subtract 8 yd from both sides
The missing side length is 7 yd.
Which equation is equivalent to I = prt?
A. P = I + rt
B. P = Irt
C. P = I - rt
D. P = I/rt
Answer: Choice D. P = i/rt
This is the same as saying P = i/(rt). The parenthesis are preferred in my opinion to indicate we have rt in the denominator and not just r.
======================================
Explanation:
In the original equation, prt is the same as p*r*t. So we multiply p, r and t to get prt.
This can be thought of as p*(rt). To isolate p, we undo the multiplication done to the variable p. We will divide both sides by rt to get
i = prt
i = p*(rt)
i/(rt) = p*(rt)/(rt) ... dividing both sides by rt
i/(rt) = p
p = i/(rt)
I can’t figure out the answer to x/3-9=0
Answer:

What is the quotient when 512 is divided by -8? Show your work!!
Answer:
-64
Step-by-step explanation:512 divided by 2 can be calculated as follows. 512/2 math problems division = 256. Therefore 256 to 2 decimal places= 256. 512/2
The quotient of the equation when A = 512 / -8 = -64
Given data ,
Let the quotient of the expression be represented as A
Now , the value of A is
Let the first number be represented as p
Now , the value of p = 512
Let the second number be represented as q
Now , the value of q = -8
where A = p/q
On simplifying the equation , we get
A = 512 / ( - 8 )
A = -512 / 8
A = -64
Therefore , the quotient of the expression is A = -64

Solve the equation, 4 - (x + 1) = 6.
x = -9
x = 3
x = -3
x = 9
Answer:
x = -3
Step-by-step explanation:
[tex]4-(x+1) =6[/tex]
Distribute the negative
[tex]4 - x - 1 = 6[/tex]
Combine like terms on Left Hand Side
[tex]- x + 3 = 6[/tex]
Substract 3 from both sides
[tex]-x = 3[/tex]
Divide both sides by -1 to get rid of the negative
∴ [tex]x = - 3[/tex]
3(x+1) = 2(x-5)
Solve for x
Answer:
x = -13
Step-by-step explanation:
3(x+1) = 2(x-5)
3x + 3 = 2x - 10
3x - 2x = -10 - 3
x = -13
Answer:
x = -13
Step-by-step explanation:
To solve for x, we will have to get the equation in a form with x by itself on one side and a value on the right side.
3(x + 1) = 2(x - 5)
Distribute the 3 on the left side and the 5 on the right side.
3x + 3 = 2x - 10
Subtract 3 from both sides.
3x = 2x - 13
Subtract 2x from both sides.
x = -13
And now we have the answer of x = -13.

Bricks Placed
90
180
270
360
What’s the relationship
Answer:
[tex]b = 90w[/tex]
Step-by-step explanation:
Required
Determine the relationship
Represent the workers with w and bricks with b
First, we need to determine the constant of proportionality using:
[tex]b = kw[/tex]
Solve for k
[tex]k = \frac{b}{w}[/tex]
When w = 1; b = 90:
[tex]k = \frac{90}{1}[/tex]
[tex]k = 90[/tex]
When w = 2; k =180
[tex]k = \frac{180}{2}[/tex]
[tex]k = 90[/tex]
Notice that [tex]k = 90[/tex] in both cases;
Substitute 90 for k in [tex]b = kw[/tex]
[tex]b = 90w[/tex]
Hence; the relationship is [tex]b = 90w[/tex]

dont understand it, so yeah need some help
Answer:
-4
Step-by-step explanation:
We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.
The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.
We have the gradient, so we can put it in the equation:
y = x/2 + c
We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.
3 = 6/2 + c
3 = 3 + c
c = 0
Therefore the equation for our line is y = x/2.
We can now put in the y coordinate we were given to work out the corresponding x coordinate:
-2 = x/2
x = -4
Therefore n is -4.

The perimeter of a rectangle playing Field is 504 meters. It’s length is 6 meters shorter than twice it’s width. What is the area?
Answer:
Area = 14276
Step-by-step explanation:
Length = 2w-6
Width =w
perimeter = 2w+ 2l =504
2w+2(2w-6)=504
2w+4w-12=504
6w=516
w=86
L=2w-6
L=2(86)-6
L = 172-6
L = 166
Area = L*W
area=86*166
Area = 14276

A line has this equation: y= -9x-2
Write an equation for the parallel line that goes through (2, -3).
Answer:
y = - 9x + 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 9x - 2 ← is in slope- intercept form
with slope m = - 9
Parallel lines have equal slopes, thus
y = - 9x + c ← is the partial equation
To find c substitute (2, - 3) into the partial equation
- 3 = - 18 + c ⇒ c = - 3 + 18 = 15
y = - 9x + 15 ← equation of parallel line

Mr. Bins sold 1/2 of his farm to Mr. Frost and 100 acres to Mr. Slate. He now has 1/5 of his original farm land. How big was his farm originally? How much land does he have now? <3
Answer:
His original farm was 333 1/3 acres
He has 66 2/3 acres of his land left
Step-by-step explanation:
Lex
His total farmland = x
1/2 of x = Mr frost
100 acres = Mr slate
Remaining = 1/5x
His total farmland = Mr Frost + Mr slate + remaining farmland
x = 1/2x + 100 + 1/5x
x = 5x+2x/10 + 100
x = 7/10x + 100
x - 7/10x = 100
10x-7x/10 =100
3/10x = 100
Divide both sides by 3/10
x = 100 ÷ 3/10
= 100 × 10/3
= 1,000/3
= 333 1/3 acres
His original farm was 333 1/3 acres
He has 1/5 of his original farm
1/5 × 1000/3
= 1,000 / 15
= 66 10/15
= 66 2/3 acres
He has 66 2/3 acres of his land left
