Answer:
10 liters.
Step-by-step explanation:
Let the volume of 2% acid be x liters.
Then the volume of the 8% solution will be (x + 30) liters.
Work in amounts of pure acid: amount of acid in the 10% solution = 30 * 0.1
= 3. So we have the equation:
0.02x + 3 = 0.08(x + 30)
0.08x - 0.02x = 3 - 0.08*30
0.06x = 0.6
x = 10
So the answer is 10 liter of the 2% solution.
f(x) + n - move the graph n units up
f(x) - n - move the graph n units down
n · f(x) - stretch by n in the y-direction
1/n · f(x) - compress by n in the y-direction

Second:
Solute = what is dissolved
solvent = that which dissolves or can dissolve
You take it from here.
Answer:
We'll use this equation:
b = y - mx then we solve for b by inputting the slope (-2) into "m" and use the "x" and "y" values from the given point. (0, 3)
b = 3 --2*0
b = 3
Then we enter "b" into this equation:
y = mx +b
y = -2x + 3
