Just multiply the 12 miles by two and the gallon by 2 to get an equivalent unit rate
24 miles per 2 gallons
17.83 times 1.1
=19.613
17.83+19.613
=37.443
=37.5 dollars
The ODE appears to be
It's separable; we can write
and integrating both sides yields
Answer:
I think the answer is m= -1/3 b=7/3
Explanation:
so first, you need to make equations using the info that the question gave.
f(-2)= m(-2)+b f(4)= m(4)+b
= -2m+b =4m+b
f(-2)= 3 f(4)= 1
-2m+b= 3 4m+b=1 -(2)
b= 3+2m -(1)
substitute (1) into (2) : 4m+(3+2m)=1
4m+2m+3=1
6m=1-3
6m= -2
m= -2/6
m= -1/3
Substitute m= -1/3 into (2)
4(-1/3) + b=1
-4/3 +b =1
b= 1+ 4/3
b= 7/3
Therefore, m= -1/3 b=7/3
and that's how you do it
