Answer:

In 9 days will the second warehouse have 1.5 times more coal than the first one

Step-by-step explanation:

The coal left in warehouses after x days can be found using the equation:

  • first warehouse: 185 - 15x
  • second warehouse= 237-18x

Let the second warehouse have 1.5 times more coal than the first one after n days then  

  1. 1.5 ×(185 - 15n)=237-18n  which gives:
  2. 277,5-22,5n=237-18n and
  3. 40,5=4,5n
  4. 9=n

PLZ HELP ASAP I don’t know the answer and I keep getting it wrong

I believe the Slope- intercept formula is y = mx + b

Slope is your m = -4
Point: (2, -4)
x = 2
b is your y-intercept = -4

Answer: y = -4(2)+ -4 or -4(2)-4?

So sorry if it’s wrong but I hope this helps
