Answer:
Option A. 
Step-by-step explanation:
Point to remember while solving the question of function,
Here, 'f' is the parent function and 
is the inverse of the function 'f'.
So for the given function,
f(x) = 2x - 2
For x = -2
Therefore, Option A will be the correct answer.
Answer: 11/48
Step-by-step explanation:
(11/12) / 4 = 11/12 * 1/4 = (11*1)/(12*4) = 11/48
Answer:
C seems right
Step-by-step
seems more work then needs be but 7+5= 12 and she originally had 23. so the equation of adding the 7+5 would just be adding up the ones removed together then adding the -23 to the equation is how many Amy had to begin with. so it would be <u><em>23-7+5 </em></u>= 12. others dont seem right since when you add () to an equation that means your multiplying and you wouldn't be multiplying here and for D to be right it needs to be switched around or you'd end up with a - number and she wouldn't have a - number of blocks. just divide up a problem if need be and break it down to smaller parts to make it easier to deal with.
There are 500 even numbers from 1 to 1000 starting with 2 and ending with 998. The sequence of even numbers is an arithmetic sequence with a common difference of 2. Using the equation for the arithmetic series,
S = (a1 + an)(n/2)
and substituting,
S = (2 + 998)(500/2)
we get,
S = 250,000
Therefore, the sum of all even numbers between 1 and 1000 is 250,000.
