plug in -4 in for x. then solve.
h(-4)=1/2(-4)-1
h(-4)= -3
The standard form of a quadratic equation is
,
where 
, 
, and 
are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.
In this case, the given equation is
Since 
is on the right side of the equation, we subtract that from both sides. The resulting equation is
Looking at the standard form equation , we can see that
Answer: 23.4 is the answer
s= p+3
(number of sports drinks= s)
(pizza slices= p)
