Answer:
1.not 2×4 is 2+4 answer should be 6x⁶
2.not 3+4 is 3×4 answer should be 12a⁷
3.miss 1 should x^(6+1+3) should be x¹⁰
4.base different, and just become 81×8=648
Answer:
$6,427.99
Step-by-step explanation:
-We first find the effective annual interest rate as follows:

#We the use this rate to find the compounded amount after 18 years:

Hence, the amount after 18 years is $6,427.99
In order to find this out, we just needed to find out which one has the same smallest fraction
25 / 35. Divided this by 5 and we will get 5/7 >>> smallest fraction
15/21 . Divided this by 3 and we also will get 5/7 >> smallest fraction
So the answer would be : B. 15/21
hope this helps
If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!
I believe the answer is A
