A liquid solution is slowly leaking from a container. The graph shows the
milliliters of solution, y, remaining in the container after x minutes.
What is the y-intercept of the line and what does it represent in this scenario?

If 1 is divided by the sum of y& 4. the result is equal to 3 divided by 4 .find the value of m?

Can someone check if i did this correct. it’s number 4 if you’re wondering.

Each person in an it department of 25 people works on at least one of 3 major projects: system security, program implementation, platform development. 10 people work on system security, 13 work on program implementation, and 12 work on platform development. 4 people work on system security and platform development, 5 people work on program implementation and platform development, and 2 people work on all three projects. how many people work on system security and program implementation?
