Answer:
$12,921.09
Step-by-step explanation:
1. 9,000*1.041(added 4.1 percent to whole debt)=$9369
2. 9,369*1.041=9,753.13
3. 9,753.13*1.041=10,153.01
4. 10,153.01*1.041=10,569.28
5. 10,569.28*1.041=11,002.62
6. 11,002.62*1.041=11,453.73
7. 11,453.73*1.041=11,923.33
8. 11,923.33*1.041=12,412.19
9. 12,412.19*1.041=12,921.09
$<u>12,921.09</u>
x ≤ 7
1. add 4 to both sides x-4+4 ≤ 3+4
2. simplify x ≤ 7
an=1*2.5^(n-1)
=2.5^(n-1)
Complete question below:
What value, written as a decimal, should Lena use as the common ratio? Lena is asked to write an explicit formula for the graphed geometric sequence. On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2.5), (3, 6.25).
Solution
Point (1, 1), (2, 2.5), (3, 6.25).
a=1
ar=2.5
ar^2=6.25
From ar and ar^2
r=6.25/2.5
=2.5
r=2.5
an=ar^(n-1)
Therefore, the explicit formula is
9514 1404 393
B 2(−10x+2y−1)
The greatest common factor is 2. Factoring that out gives the factorization shown in choice B.
2(-10x +2y -1)
__
You could factor out -2. Doing that would give ...
-2(10x -2y +1) . . . . . . . doesn't match choice C
