I'm pretty sure you already solved this by now, but I'll say the answer anyway. This problem has already been solved by another as a verified answer.
This is the concept of financial algebra, we are required to calculate the value of stock ABC which follows the model given by:
y=12.21x+37.42
given that x=62 days,
the value of th estock after 62 days will be given by:
y=12.21(62)+37.42
y=757.02+37.42
y=794.44
ABC will be worth $794.44
I take no credit for this answer. It was solved by CastleRook.
Answer:
Answer is A
Step-by-step explanation:
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
