Intercepts can be used to describe the starting point of something. This is because whether it is an x or y intercept, the opposite value contains a 0. Ex: (x,0) or (0, y)
Answer:
a) 4 - 
b) 1 - 
c) 6 - 
Step-by-step explanation:
It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.
We start with:

We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):

Then we multiply each side by 2 to get rid of the 1/2, answer #1:

Finally, we divide each side by t^2 to isolate a (answer #6):

Answer:
its either 10 or 19
Step-by-step explanation:
If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.
It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.
Since it has two or more places, 5 and 10 are also factors.
