Answer:
2x+4=2x+7
Step-by-step explanation:
2x+4=2x+7
-4 -4
2x=2x+3
-2x -2x
0=3
Zero does not equal to 3 so there's no solution
Answer: 256
Step-by-step explanation:
m=-6 and y-int of (0,5) gives you y = -6x + 5.
Looking through those other equations, you're looking for variations of that equation.
#1 is NOT.
#2 IS, because -6x + 5 is the same as 5 - 6x.
#3 is NOT.
#4 is NOT.
#5 is NOT.
#6 is NOT.
It looks like #2 is the only one.
It would be c. A perfect correlation will be either a 1 or a -1. The answer that is closest to one of these is c, -0.9.
