8-2 and then 3 divided by 6 which will give you 0.5 so x=0.5
The simple interest rate equation is I = Prt
I = interest
P = principle ($54,000)
r = rate (3.875%)
t = time (3 months, so .25 years)
I = Prt
I = (54,000)*(.03875)*(.25)
I = $523.125
Figure out slope by using:
(y2-y1)/(x2-x1)
Plug in values:
29.98-15.49/50-25
Simplify:
14.49/25 = 0.5796
Then, use this ratio for the 40 lbs bag. So, then:
40*0.5796 = 23.184
So, your price for the 40 lbs bag should be $23.18 because cents only go up to 2 decimal places (otherwise, it would be $23.184).
A = (2+9)/2
a = 11/2
a = 5.5

b = (4+4)/2
b = 4

d = √(9-2)²+(4-4)²
d = √7²+0²
r = 3,5
____________________
(x-a)² + (y-b)² = r²
(x-5.5)² + (y-4)² = 3,5²
(x-5.5)² + (y-4)² = 12.25
I am not to sure about this one
