You can get the different results for the same equation if one of the results is a variable. This is because, in this problem, x=12.
Answer:
8 capsules
Step-by-step explanation:
The 100 mL of solution requires 4 capsules for its preparation. (4 × 150 mg = 600 mg). So, twice as much solution (200 mL) will require twice as many capsules. It will take 8 capsules to make 200 mL of solution.
Answer:
y = -1/4x - 5/2.
Step-by-step explanation:
I am assuming you mean y = -1/4x + 5.
This has slope of -1/4 so the required equation has the same slope ( as they are parallel).
Using the point-slope form of the equation of a line:
y - (-3) = -1/4(x - 2)
y + 3 = -1/4(x - 2)
y = -1/4x + 1/2 - 3
y = -1/4x - 5/2
Wouldn’t it be 7*4/2? so the answer would be 14
