Let h = the number of horses in the field
Let c = number of cows in the field
There are 2 more horses than cows in the field. Therefore
h = c + 2
or
c = h - 2 (1)
There are 15 animals in the field. Therefore
h + c = 15 (2)
Substitute (1) into (2).
h + (h - 2) = 15
2h - 2 = 15
Answer:
The correct equation is
2h - 2 = 15
Full price of popcorn: $3.50
Price of popcorn after half the movie: $1.75
price of drinks: $1.35
The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over."
$1.75*3=$5.25
$1.35*3=$4.05
the price of the 3 orders of popcorn would be $5.25
The price of the 3 orders of drink would be $4.05
5.25 + 4.05 = $9.30
In total the 3 orders of popcorn and 3 orders of drink would cost $9.30
Hope this helps! :)
Answer:
Step-by-step explanation:
A polynomial function is given by the form:
Where a is the leading coefficient, and <em>p</em> and <em>q</em> are the roots (more can be added if necessary).
Our zeros are 3 and (-2 + 2i).
And our leading coefficient <em>a </em>= 1.
Furthermore, by the Complex Root Theorem, if (-2 + 2i) is a zero, then (-2 - 2i) must also be a zero.
So, by substitution, we acquire:
Simplify:
Expand the second and third factors:
Therefore, our polynomial function of least degree and the given zeros will be:
A represents it, since it’s on the negative side
