Answer:
A rational expression that has the nonpermissible values
and
is
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of
, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
(1)
Then, the factorized form of
must be:
(2)
If we know that
, then the rational expression is:
(3)
A rational expression that has the nonpermissible values
and
is
.
i would pick number C) since i think it would be the correct answer
Answer:
(4*10)+(7*1/100)=40+7/100=40 7/100
Step-by-step explanation:
We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:
(1) x + y = 39
(2) 4x + 7y = 204
x- number of DVDs; y - number of CDs
solving, x= 23 DVDs
y = 16 CDs
