Vertex of the equation is (-2.5, -2.25) 

y=x^2+5x+4 ----> find x using -b/2a

-5/2=-2.5

Now plug it in the equation to find the y-value

(-2.5)^2+5(-2.5)+4=-2.25

Alton had $725 for Medicare, $3000 for state income tax, and $3100 for
ella [17]

Answer:

\$6825

Step-by-step explanation:

Amount deducted for Medicare = $725

Amount deducted for state income tax = $3000

Amount deducted for Social security = $3100

To find: Total amount deducted from Alton's pay for FICA last year

Solution:

Total amount deducted from Alton's pay for FICA last year = Amount deducted for Medicare + Amount deducted for state income tax + Amount deducted for Social security   = 725+3000+3100

On adding 725 and 3000, we get 725+3000=3725

On adding 3725 and 3100, we get 3725+3100=6825

So, amount deducted = \$6825
