Answer:
Option c.
Step-by-step explanation:
It is given that the piecewise function represents the Social Security taxes for 2009.

We need to find Rachel's security tax if she earned $102,000 in 2009.
Since 102,000 lies in
, therefore

Put x=102000.


So, the Social Security tax is $6324.
Therefore, the correct option is c.
X^2/a^2+y^2/b^2=1
a^2=100 a=10
b^2=64 b=8
c^2=a^2-b^2
c=6
Answer:
AC = 25
Step-by-step explanation:
Since ∠A = ∠C then the triangle is isosceles, thus BC and AB are congruent, that is
BC = AB, substitute values
7x - 1 = 5x + 5 ( subtract 5x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Hence
AC = 6x + 7 = (6 × 3) + 7 = 18 + 7 = 25
