What you should see in this case is that you have a third degree polynomial because you have three different zeros.
We have then that the generic form factorized for a polynomial of third degree is:
(x-a) * (x-b) * (x-c)
where,
a, b, c: real numbers.
For our case:
(x + 10) * (x + 4) * (x-1)
answer:
a polynomial function in factored form is
(x + 10) * (x + 4) * (x-1)
Answer:
x = 3, y = 8
Step-by-step explanation:
by substitution
4x + (x+5) = 20
5x + 5 = 20
x = 3
y = x + 5 = 3 + 5 = 8
A=p (1+I/k)^kn
A future value 160000
p present value ?
I interest rate 6/100=0.06
K compounded semiannual 2
T time 18-7=11years
160000=p (1+0.06/2)^(2×11)
Divide each side by (1+0.06/2)^(2×11)
P=160,000÷(1+0.06÷2)^(2×11)
P=83,502.8
Hope it helps:-)
Use the formula y=C(1-r)^x
=135(1-what the rate of change is )^5*7
36/3=12
12*30=360
i'm pretty sure that's the answer
