Wouldn’t it be (-2+12)/2 which is 10/2 which is 5. Because that’s how the midpoint formula works you find starting point and end point, you add those two up together and then divide by 2. So the answer for this one is 5.
Answer:
2x*x
2x*-5
1*x
1*-5
2x²-10x+x-10 add numbers that have similar variables
-2x²-10x+x-10
=[-2x²-9x-10]
Answer:
infinitely many solutions
Step-by-step explanation:
<span>He runs 69.75 miles.
Explanation:This can be represented as an arithmetic sequence, since the same number of miles is added each day.
The explicit form for this arithmetic sequence would be 1.75+0.25(n-1). However, we also need the sum. Using technology,
