Answer:
y = one-half x + three-fourths
Step-by-step explanation:
The 2-point form of the equation of a line can be used for starters.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (11/12 -19/20)/(1/3 -2/5)(x -2/5) +19/20 . . . . fill in given values
y = ((55 -57)/60)/((5 -6)/15)(x -8/20) +19/20 . . simplify a little
y = (-1/30)/(-2/30)(x -8/20) +19/20 . . . . . . . . . . and a little more ...
y = 1/2x -4/20 +19/20
y = 1/2x +15/20
y = 1/2x +3/4 . . . . line in slope-intercept form
Answer:
Step-by-step explanation:
In 5 liters, there is 4% salt.
Lets find liters of salt.
First, converting 4% to decimal (dividing by 100):
4% = 4/100 = 0.04
0.04 * 5 = 0.2
So, there is 0.2 liters of salt.
Now, x liters of water is added to total, so total is now:
5 + x
The concentration of salt will be amount of salt divided by amount of salt water solution.
Amount of salt = 0.2 (as seen above)
Amount of new salt water solution = x + 5
So,
Concentration of salt in new solution is 
2nd choice is right.

Answer:
A. p = $17.95n - $1,250.00
Step-by-step explanation:
Profit (p) = net revenue - expenditure
Net revenue = charge for transfer of n videos - expense for n blank DVD
charge per video transfer = $20.40
charge for n video transfer = $20.40 × n = $20.40n
expense per blank DVD = $2.45
expense for n blank DVD = $2.45 × n = $2.45n
Net revenue = $20.40n - $2.45n = $17.95n
expenditure = $1,250.00
Therefore, p = $17.95n - $1,250.00
