Answer:
it flip it to the left side and it becomes a p
it flip it to the right side and it becomes a q
Step-by-step explanation:
Step-by-step explanation:
There is 1 root at x = 1, where the function crosses the x-axis.
There are 2 roots at x = -2, where the function touches the x-axis but does not cross.
So there are 3 real roots total.
The function is:
y = (x − 1) (x − (-2))²
y = (x − 1) (x + 2)²
Answer:
the price per pound she paid for the ground turkey = $10.515
the price per pound for the white fish
= $5.915
Step-by-step explanation:
Let x = cost of one pound of ground turkey.
Let y = cost of one pound of white
fish
Mrs.Willy bought 3 1/2 (7/2) pounds of ground turkey and 2 1/2(5/2) pounds of white fish and she paid a total of $51.59. This means
7x/2 + 5y/2= 51.59 - - - - - - -1
the white fish is $4.60 per pound cheaper than the ground turkey. This means
y = x - 4.60
To find the price per pound she paid for the ground turkey and the price per pound for the white fish,
substitute y= x - 4.60 in equation 1
7x/2 + 5y/2= 51.59
3.5x +2.5y = 51.59
3.5x + 2.5(x-4.6) = 51.59
3.5x + 2.5x - 11.5= 51.59
6x = 51.59+11.5= 63.09
x = 63.09/6 = $10.515
Substituting x = 10.515 in equation y = x - 4.60,
y = 10.515-4.60
= $5.915
