Answer:
no
Step-by-step explanation:
No, it is not since 2 points have the same x-coordinate and different y-coordinates.
B= 2000 + CD
98000 = B + CD
substitute b in
98000 = 2000 + CD + CD
add variables
98000 = 2000 + 2CD
subtract 2000 from each side
96000 = 2CD
divide each side by 2
48000 = CD

Answer:
0, 2 . . . . . (any pair of consecutive even integers)
Step-by-step explanation:
You want a pair of consecutive even integers such that twice the lesser is 4 less than two times the greater.
<h3>Setup</h3>
Let x represent the lesser of the two even integers. Then the greater is (x+2) and the given relation is ...
2x = 2(x+2) -4
<h3>Solution</h3>
Simplifying gives ...
2x = 2x +4 -4
2x = 2x . . . . . . . true for any even integer x
Any pair of consecutive even integers will satisfy the relation.
one such pair is 0, 2
<em>check</em>: 2(2) -4 = 2(0)
