Answer:
y = 0,5 x + (-3)
Step-by-step explanation:
We can see from the graph that when y = -3, the line crosses y axis, therefore
y = ? x + (-3)
We can also spot that when x = 6, y = 0
// now mark ? sign as a variable k and put the given x and y values into the previous expression
y = k * x - 3
0 = k * 6 - 3
k * 6 = 3
k = 3/6
k = 0,5

Answer:
Step-by-step explanation:
Let 25% solution is x liters, then 50% solution is (80 - x) liters.
<u>Acid content is going to be same:</u>
- 0.25x + 0.5(80 - x) = 80*0.4
- 0.25x - 0.5x + 40 = 32
- 0.25x = 8
- x = 8/0.25
- x = 32 liters
So 32 liters of 25% solution and 80 - 32 = 48 liters of 50% solution
