Help please? if JKhas endpoints J(-2,3) and k(6,5), and LN has endpoints L(0,7) and N(4,1), then JK and LN have the same midpoin
t. If GH has endpoints G(-8,1) and H(4,5), then the midpoint M of GH lies on the line y= -x+1.
1 answer:
In this item, it is assumed that what is asked is that if the statement is TRUE or FALSE.
Part A:
The coordinates of the midpoint of the given endpoints of the line is equal to half of the sum of the coordinates.
Line JK
abscissa = (-2 + 6) / 2 = 2
ordinate = (3 + 5) / 2 = 4
Midpoint is (2, 4)
Line LN
abscissa = (0 + 4) / 2 = 2
ordinate = (7 + 1) / 2 = 4
Midpoint is (2, 4)
Hence, the statement is TRUE.
Part B:
abscissa = (-8 + 4)/ 2= -2
ordinate = (1 + 5) / 2 = 3
Midpoint = (-2, 3)
Substituting the point to the given equation,
y = - x + 1
3 = -(-2) + 1 = 3
Thus, all statement is TRUE.

Answer: Deshi will have 302 marbles and Elaheh will have 519.
Step-by-step explanation:
Deshi's Marbles will subtract 125.
427 - 125 = 302.
Elaheh's Marbles will add 125.
394 + 125= 519.

I'm going to just go by this because of research and you didn't show the 4 problems so if this fixes your question then there you go
<u>Direct Variation:</u> 

when y = 7: 
14 = 15x

<u>Inverse variation:</u> y*x = k
15 * 2 = k
30 = k
when y = 7: 7 * x = 30
