Second one is the correct answer
Answer:
Step-by-step explanation:
y = -2x - 3
7x - 5y = -6
7x - 5(-2x - 3) = -6
7x + 10x + 15 = -6
17x = -21
x = -21/17
y = -2(-21/17) - 51/17
y = 42/17 - 51/17
y = -9/17
(-21/17, -9/17)
The inequality you require is
The number of bottles left at the end of each day is 48 - 3x. So it is:-
48 - 3x < 10
Solving the inequality to find the last part of question:-
-3x < 10 - 48
-3x < -38
x > 38/3 = 12 2/3
So answer is 13 days.
Slope is 3/2
The Y intercept is 12
