Answer:
8:45
Step-by-step explanation:
5x48=240 sec
240 sec = 4 min
8:49-4min= 8:45
4 x 10^-7 (7 x 10^-9) (1 x 10^4) (2 x 10^4)
Answer:
x=6561
Step-by-step explanation:
We can solve this equation for x to get

The answer to this is
3(x+1)(x+8)
x intercept of 6 means (6,0) is on the line
y intercept of 0 means (0,0) is on the line
so the slope is (0-0)/(6-0) = 0
Answer: 0
Note: The question is actually bad; the line through the origin with slope zero is the X axis itself in which case it wouldn't be right to call the X intercept (just) (6,0).
