ANSWER
The linear equation is: y = 80x + 65
Te cost for 40 football jerseys: $3265
EXPLANATION
Let 'x' be the number of jerseys and 'y' the cost of x jerseys.
Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.
Therefore, the cost 'y' of x jerseys is:
Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:
Step-by-step explanation:
The standard equation of a circle is
Center = (h, k)
#1
Center = (0,2)
h = 0
k = 2
r = 5
#2
Center = (-4,-5)
h = -4
k = -5
r =
#3
Center =(-1,3)
h = -1
k = 3
r = 8
#4
Center: (9,0)
h = 9
k = 0
r =
