<span>We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:
</span>
i) 2x + 2y = 8
ii) x + y = 4
<span>
use equation ii) to write y in terms of x as : y=4-x,
substitute y =4-x in equation i):
</span>2x + 2y = 8
2x + 2(4-x) = 8
<span>2x+8-2x=8
8=8
this is always true, which means the equations have infinitely many common solutions.
Answer: </span><span>There are infinitely many solutions.</span><span>

Answer:
1 kilometer
0.621371 miles
Step-by-step explanation:
Given data
In the given table we are presented with the conversion table for common units and we are required to present the conversion for kilometers to miles
Hence the conversion from kilometers to miles is presented below
1 kilometer
0.621371 mile
The answer would be 37 r. 9
