1/3.
Step-by-step explanation:
The slope of the given line = (-4 - -7)/(2-3)
= 3 / -1
= -3.
The line perpendicular to this has slope - 1 / (-3)
= 1/3.
(2,6) it’s where they cross. If there isn’t a graph make the two equations equal to each other to find x then plug in x to either equation to find y

10 liters of pure alcohol
Step-by-step explanation:
Create an equation where x is the number of liters of pure alcohol needed:
1x + (0.4)(20) = (20 + x)(0.6)
Simplify:
x + 8 = 0.6x + 12
Solve for x:
0.4x = 4
x = 10
So, 10 liters of pure alcohol have to be added
