Step-by-step explanation:
its either you explain it wrong or the answer is jenny doesn't need to spend anymore money to have more baseball cards then you because she already has more then you.
You bought baseball cards at $8 for 12 cards and added them to your collection of 128 baseball cards
128+12=140
Jenny bought baseball cards at $6 for 8 and added them to her collection of 150 baseball cards
150+8=150
150>140
All we have to do is multiply $64.70 times 48 to get the total amount paid.
The answer is $3,105.60. Hope that helps!
Answer:
Step-by-step explanation:
By the conjugate rule, if -4i is a root, then so is +4i. So we have 2 roots, thus, we have a second degree polynomial (namely, a quadratic). If
x = -4i, then
x + 4i is a root.
If
x = 4i, then
x - 4i is a root.
Having (x - 4i)(x + 4i) as roots, we can now FOIL them together to get a polynomial of least degree.
FOILing gives us
Notice that the +4ix and the -4ix cancel each other out, leaving you with
Since
we can make the substitution:
which simplifies to
In function notation form:
