Assume, instead of > there was a =
In that case, x ÷ 7 = 3, then x would be 21. But we want a value that will be exceed this 21. So the only option you have is 63.
624 is divided by 8. Hope this helps.
Answer:
{(0,-5), (1, -3), (2, -1), (3, 1)
Step-by-step explanation:
If you plug in 1 for x you get f(x)=2(1)-5 which equals 2-5=-3
You would repeat these steps just going up by one number every time
Answer:
Step-by-step explanation:
third option I believe
It'd be easier to do #18 if y ou were to break it up:
14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2
14(1+14)
= ---------------- = 7(15) = 105
2
The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.
The final sum is 210 + 14 = 224 (answer)
