The answer is $29.3 because you multiply 2.93 times the ten gallons of gas.
Multiply:
6•12=72
Then, you subtract 39 from 72:
72-39=33
33 containers would still need to be set up.
y -
y1 = m (x - x1)
where m is the slope and (x1 , y1) is the point given
m = (y2-y1)\(x2-x1)
we have <span>(-5,-3) and (6,1)
so: m = (1- -3) / (6- -5) = (1+3)/(6+5) = 4/11
and the equation of the line is:
</span>y -
y1 = m (x - x1)
y-1 = 4/11 (x-6)
simplify:
y = 4/11 x - 24/11 +1

I hope that
helps!
