Answer:
-40 square root of 10k²
Step-by-step explanation:
4 people email 3 more people each so 12 people are emailed, then these 12 people email 3 more people each, so 36 people are emailed.
3x + 4y + 8 = 0
4y = -3x - 8
y = -3/4x - 2....slope here is -3/4. A parallel line will have the same slope.
y = mx + b
slope(m) = -3/4
y int (b) = 4
so ur equation is : y = -3/4x + 4
