Answer:
$156.86
Step-by-step explanation:
136.40 multiplied by .15 equals 20.46
136.40 plus 20.46 equals 156.86

Price of
Computer(C) + Printer(P) + Scanner (S) = $2543
Price of Computer:
C = 1502 + P
Price of Printer:
P = 123 + S
So Price of computer now becomes:
C = 1502 + 123 + S (Here we replace P with 123 + S)
It is Algebra from here:
C + P + S = 2543
(1502 + 123 + S) + (123 + S) + S = 2543
1748 + 3S = 2543
3S = 2543-1748
3S = 795
S = 795/3
S = 265
C = 1502 + 123 + S
C = 1502 + 123 + 265
C = $1890

Answer:
The roots of the given equation is x=4,3i,-3i
Step-by-step explanation:
The given cubic equation is
![y=x^3-4x^2+9x-36](https://tex.z-dn.net/?f=y%3Dx%5E3-4x%5E2%2B9x-36)
To find the roots we have to equate the equation to zero
ie, ![x^3-4x^2+9x-36=0](https://tex.z-dn.net/?f=x%5E3-4x%5E2%2B9x-36%3D0)
It can be done by using Synthetic division method
Therfore [tex](x-1) is not a factor or root
now put x=-1
Therfore [tex](x-1) is not a factor or root
similarly let x=2,-2,3,-3 all not equal to zero so the are not roots.
let x-4 is a factor of given equation
then it satifies the equation ie (x-4) is a root
And it may be written as
[tex](x-4)(x^2+9)
answer:
$0.75
Step-by-step explanation:
the function can be represented as:
f(x)=0.25x+3.5
the function produces the following values for years 1, 2, and 3 respectively:
f(1)=0.25(1)+3.5=3.75
f(2)=0.25(2)+3.5=4.00
f(3)=0.25(3)+3.5=4.25
therefore,
there is a $0.75 increase per year
