Answer:
You will need 220 mL of the 60% solution and 80 mL of pure alcohol.
Step-by-step explanation:
Let 'x' be the amount of 50% alcohol solution and y the amount of pure alcohol.
Therefore:
(0.5x + y)/300 = 0.65 ⇒ 0.5x + y = 190
x + y = 300
Solving the sistem of equations:
x = 220 and y = 080
Therefore, You will need
220 mL of the 60% solution
and 80 mL of pure alcohol.
F)x) is shaped like a V with the vertex at the origin so its is one of the choices.
B is also one because its |x| moved up 3 unuts
So is D.
Looking at the graph above, you are able to tell which points are true to the equation.
C. (5/2, 5) is true to the equation because it is located within the red region.
