Not sure if this is college math and what you're even asking, but if I'm understanding it right, it takes Eric 30 30 minutes. meaning 900 minutes. It takes his brother 20 20 minutes meaning 400 minutes. You're asking for the average time with them working together so 900+400=1300, 1300/2=650. It takes them 650minutes working together. 650 isn't a perfect square so I'd rather not expand on that part.

Which graft represent -3x+5y=-15
azamat

The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

-3x + 5y = -15

The above function shows a linear function we can write it as:

5y = 3x - 15

y = (3x - 15)/5

If x = 0, y = -3

x = 1, y = -2.4

x = 2, y = -1.8

x = -1, y = -3.6

x = -2, y = -4.2

Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.
