the answer is JKN = 57
Step-by-step explanation:
JKN is JKL + LKN
we know that LKM = 42, and LKN is half of that because KN bisects LKM (splits into 2 equal parts)
so, LKN is half of 42
LKN = 21
to find JKL, subtract 42 from 78
JKL = 36
36 + 21 = 57

The constant of proportionality in the equation y= 2X is 2.
A theater is tracking the number of adults and children in the audience at
various shows. The table shows how the number of adults and children
are related
Select the equation that matches the relationship.
X+y = 1000
X-y1000
y-x= 1000
Y= 1000xc
Adults
Children
500

400
600

650 I Need help i dont understand!!!!!!!!
Answers
Answer:
The correct option is;
x + y = 1000
Step-by-step explanation:
The data from the table can be presented as follows
Adults (x) [tex]{}[/tex] Children (y)
500 [tex]{}[/tex] 500
450 [tex]{}[/tex] 550
400 [tex]{}[/tex] 600
350 [tex]{}[/tex] 650
Therefore, we have the rate of change of the children, y to the adults, x, which is also the slope of the graph of the data given as follows;
The slope, m = dy/dx = (650 - 500)/(350 - 500) = 150/(-150) = -1
m = -1
The function of the graph in point and slope form, using the first point, becomes;
y - 500 = -1 × (x - 500) = -x + 500
∴ y - 500 = -x + 500
y + x = 500 + 500 = 1,000
Which gives
y + x = 1,000
y + x = x + y = 1,000

Jane contribuyó con $ 10,000 y Julie contribuyó con $ 6,000. Después de un año, la empresa obtuvo una ganancia de $ 4,000. ¿Qué proporción de las ganancias debería tomar Julie si se comparten en la misma proporción que sus contribuciones originales?
Answers
Answer:
Ganancias Julie= $1,500
Step-by-step explanation:
Dada la sigueinte información:
Jane contribuyó con $ 10,000 y Julie contribuyó con $ 6,000. Después de un año, la empresa obtuvo una ganancia de $ 4,000.
Primero, debemos calcular la proporción de aportes de cada una:
Jane= 10,000/16,000= 0.625
Julie= 6,000/16,000= 0.375
Ahora, lo que le corresponde a Julie de las ganancias:
Ganancias= 4,000*0.0375
Ganancias Julie= $1,500
Point J located at (2, 7) is rotated 90 degrees counterclockwise about (-1, -3). What is the y-coordinate of J’?
A. 9
B. 0
C. -11
D. -9
Answers
Given:
Coordinates of point J are J(2,7).
It is rotated 90 degrees counterclockwise about (-1, -3).
To find:
The y-coordinate of J’.
Solution:
If a figure rotated 90 degrees counterclockwise about a point (a,b), then
[tex](x,y)\to (-(y-b)+a,(x-a)+b)[/tex]
Point J is rotated 90 degrees counterclockwise about (-1, -3). So, a=-1 and b=-3.
[tex](x,y)\to (-(y-(-3))+(-1),(x-(-1))+(-3))[/tex]
[tex](x,y)\to (-(y+3)-1,(x+1)-3)[/tex]
[tex](x,y)\to (-y-3-1,x+1-3)[/tex]
[tex](x,y)\to (-y-4,x-2)[/tex]
Coordinates of point J are J(2,7).
[tex]J(2,7)\to J'(-7-4,2-2)[/tex]
[tex]J(2,7)\to J'(-11,0)[/tex]
Therefore, the y-coordinate of J' is 0. Hence, the correct option is B.

= -$60x
Where x = number of times Mike withdrew
b) answer as an integer
-$60 * 3
= -$180
c) answer in a sentence

The points (6,r) and (9, 9) lie on a line with slope 5. Find the missing coordinate r.
Answers
Answer:
r = -6
Step-by-step explanation:
Use the slope formula and solve for r.
slope = y2 -y1
x2 -x1
Since you know all the numbers except for r, plug everything in and you get:
5 = 9 - r
9 - 6
So then do the arithmetic, you find that 9 - r = 15. So r must = -6.

You recently started your own company. Your first year in business, your company reported a net loss of $1,250. The next year, your company made a $3,475 net profit. The year after that, your company reported a $2,478 net profit. What was your company's net loss or gain over the last 3 years?
Answers
Answer:
$4703
Step-by-step explanation:
Given that :
First year :
Net loss = $1250
2nd year:
Net profit = $3475
3rd year :
Net profit = 2478
Net loss or gain over the last 3 years :
Let Net loss be represented as negative and net profit as positive
Net loss + net profit + net profit
(-$1250 + $3475 + $2478)
$4703 net gain over the last 3 years

Solve for x with given angle measures.
Answers
Answer:
Step-by-step exx=3planation:
The exterior angle is equal to the sum of the opposite interior angles
3x^2 -6x+8x = 2x^2 +3x+6
Combine like terms
3x^2+2x=2x^2+3x+6
Subtract 2x^2 from each side
3x^2+2x -2x^2=2x^2-2x^2+3x+6
x^2+2x=3x+6
Subtract 3x from each side
x^2+2x-3x=3x-3x+6
x^2-x=6
Subtract 6 from each side
x^2 -x-6 =0
Factor
( x-3)(x+2) =0
Using the zero product property
x-3 =0 x+2 =0
x=3 x=-2
But x cannot be negative since an angle would have a negative value so
x=3
Check
3x^2 -6x+8x = 2x^2 +3x+6
3 ( 3)^2 -6(3) +8(3) = 2 (3)^2 +3(3)+6
3*9 -18 +24 = 2 *9 +9+6
27 -18+24 = 18+9+6
