which expression represents the distance between the two points x and y on the number line -4 and 3
2 answers:
Answer with explanation:
The two points on the number line are
x = -4
y=3
The distance is a positive Quantity.
So, Distance between x and y can be written as:
=|x-y| or |y-x|
=|3-(-4)| or |-4-3|
=|3+4| or |-7|
=|7| or |-7|
=7 Units
The expression will be : =|x-y| or |y-x|
=|3-(-4)| or |-4-3|
It would have to be 3 because distance can't be a negative number.

A. 2.8x+3
B. -73/156
C. 6 10/21+ 10 6/7
D is already simplified
Xy = 6
x = 2
2y = 6
y = 6÷2
y = 3
x + y = (2) + (3) = 5
3x + (x+3) = 19
4x + 3 = 19
4x = 16
x = 4
y= x+3
y= 4+3
y= 7
