You have the original function as 2x-5
and you are given the value of x to be -1/2
Therefore, all you have to do is substitute the value of x in the function and calculate it as follows:
f(-1/2) = 2(-1/2) - 5 = -1 -5 = -6
Answer: 382.728 Estimate: nearest ten: 380 nearest <em>tenth: </em>382.7
Answer:
The answer is D, 43 
Step-by-step explanation:
If the pile gets bigger by 8 
each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8 
by 3 to find out how much the pile increased by.
8 × 3 = 25 
Now, you need to add this to your initial value to get the answer.
25 + 17 = 42 
Now simplify.
43
