The LCM of 12 and 25 is 300
The function f(x) = (6/120) x + 40
= 0.05x + 40 where x is the excess mileage over 100
If we drive it for 300 miles x will be 300-100 = 200
so cost will be 0.05*200 + 40
= 10+40 = $50 answer
(A) Y= 2x+3
(B) Y= -x+6
(C) Independent. They are two distinct non-parallel lines that cross at one point.
here are A,B,& C not to sure about D
I believe it would be 6 units long since we are 2 units away 2-2 and 8-2 would be a 6 unit difference i hope this helps!
