Answer:
Step-by-step explanation:
you need the formula (y-y1) = m(x-x1) that uses a slope and a point
m=(y1-y2)/(x2-x1)= 6-1/6+6=5/12
now pic any poit out of the 2 given ones
Answer:
(y-6) =(5/12)(x-6)
same for all the other
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left
Five hinder and fourty six and two hundred and ten
Since 2+8 =10 you would just have 3 left to add so it would be 10+3=13
