I would say 2.5 becasue there are two lines between the -2 and -1 so it would be half. SO my awnser is 2.5
i hope this helped you
Have a good day
if it is wrong tell me
Answer:
y= -3x + 4
Step-by-step explanation:
I: 12x-5y=0
II:(x+12)^2+(y-5)^2=169
with I:
12x=5y
x=(5/12)y
-> substitute x in II:
((5/12)y+12)^2+(y-5)^2=169
(25/144)y^2+10y+144+y^2-10y+25=169
(25/144)y^2+y^2+10y-10y+144+25=169
(25/144)y^2+y^2+144+25=169
(25/144)y^2+y^2+169=169
(25/144)y^2+y^2=0
y^2=0
y=0
insert into I:
12x=0
x=0
-> only intersection is at (0,0) = option B
1.94 / 8 = 0.2425 rounds to 0.24....so unit price is 24 cents per gallon
