Answer:
$1.65.
Step-by-step explanation:
Let x represent cost of each bag of birdseed.
We have been given that Andy bought 3 bags of a new birdseed mixture on sale. Cost of 3 bags of birdseed would be .
The birds in his yard like it so well that his friend Mike bought 5 bags. Cost of 3 bags of birdseed would be .
We are also told that together they spent $13.20, we can represent this information in an equation as:
Therefore, the cost of each bag of birdseed would be $1.65.
Given :
Set of x-intercepts {-3,1,7},
point through which it passes (-2,54)
Now,
Step 1: Substitute value of x intercepts in equation, , we get,
... equation (1)
Step 2: substitute x an y with the point through which it passes,
∴
Step 3: Now, substituting value of a in equation (1), we have
(Requited cubic equation)
5.092in cubic and 1620π
divide by 2 on both sides.
3/2
x=1.5
