(X^2+8x)-(x-8)=0
x(x+8)-1(x+8)=0
(X-1)(x+8)=0
X= 1
X= -8
Answer:
The price of price of the stock after it has been owned for 12 weeks is $92.55
Step-by-step explanation:
Given: The price of a particular stock is represented by the linear equation
y = -0.91x + 103.47
where x represents the number of weeks the stock has been owned and y represents the price of the stock, in dollars.
We have to find the price of price of the stock after it has been owned for 12 weeks.
Since , x represents the number of weeks the stock has been owned.
Thus, by substitute, x = 12
We get the value of y , the price of stocks.
Thus, y(x) = -0.91x + 103.47
⇒ y(12) = -0.91(12) + 103.47
⇒ y(12) = -10.92 + 103.47
Solving , we get,
⇒ y(12) = 92.55
Thus, the price of price of the stock after it has been owned for 12 weeks is $92.55.
Multiplicity is how many times the root (or zero) is repeated
example, in

the root b has a multiplicity of n and the root d has a multiplicity of m
first we need to get the roots into

for (3x+5), we need to force factor out the 3 to get

factor the other one

but it is

which is equivilent to

which simplifies to

so we get

so the roots are -5/3 multiplicity 1 and 3 multiplicity 4
3 has a multilicity of 4
