Can you with this problem 5×-(14-×)=-30-2×
now eliminate the y by adding the two equations together to get
then solve for y.
30 / 0.350 = 85.7
you can fill up 85 bottles.
use the formula y^2 - y^1/x^2 - x^1
so, it would be 9-4/-2 - (-6).
this equals to 1.25.
use the formula y=mx+b to find the y intercept.
take a point, (-2, 9) and substitute x and y.
you do inverse operation and add 2.5 to each side of the equation.
your final answer should be y=1.25x+11.5.
