Answer:
The second choice, 
.
Step-by-step explanation:
Note, that the expression 
is an equation. A point 
is on the graph of 
if and only if the value of 
and 
satisfy this equation; that is: in other words, the 
-coordinate of that point (the second number in the tuple) should be equal to 
, which is equal to 
(evaluated where 
is equal to the first number in the tuple.
For each tuple in the choices, calculate the value of where is equal to the first number of each tuple. Compare the result to the second number in that tuple. That choice corresponds to a valid point on only if these two numbers match.
- First choice:
, 
. That's not the same as the second number, 
. Therefore, this point isn't on the graph of . - Second choice:
, 
. That matches the second number in the tuple. Therefore, this point is on the graph of . - Third choice:
, 
. That's not the same as the second number, 
. Therefore, this point isn't on the graph of . - Fourth choice:
, 
. That's not the same as the second number, 
. Therefore, this point isn't on the graph of .
Answer:
Prime.
Step-by-step explanation:
A^2+4a+12
Not factorable.
1.
2.
3.
4.
1. Start
2. Multiply both sides by 3
3. Subtract a from both sides
4. Subtract c from each sides
Answer:
3.5
Step-by-step explanation:
300÷85=3.529
so it would take him approximately 3.5 more days before he finishes the book
