Not sure what your asking but:
0.000675 is equivalent to 6.75x10^-4
hope this helps
15 + 7 + 9 + 7 + 4 + 4 + 3 + 3 = 52
Answer:
B. Parallel
Step-by-step explanation:
Equation 1 simplified: y = 3x+7
Equation 2 simplified: y = -x/3-3
The slopes are completely different, ruling out the possibility of the lines being parallel.
But we also see the slopes of the equations are opposite and negative to each other. Making the lines perpendicular.
