The smaller number=x
the larger number=10x
we can suggest this equation:
10x-x=81
9x=81
x=81/9=9
The smaller number is 9
The larger number is : 10x=10(9)=90
Answer: the larger number is 90.
I can eyeball points (1/2, 8), (1,4), (2,1), (3,1/4)
The pattern is each increment of 1/2 in x divides by two.
Any of the points give k=16
Check: x=1/2 4^(3/2)=2^2=8 good
x=1 4^(2-1)=4 good
x=2 4^(2-2)=1 good
x=3 4^(2-3)=1/4 good
Answer:
A.
Step-by-step explanation:
6^(1-1) + 6^(2-1) + 6^(3-1) + 6^(4-1)
= 1 + 6 + 36 + 216
= 259.
Answer:
C
Step-by-step explanation:
plug in the points for the equation on C and you'll get see that it fits
