Answer:
The answer is (5,-6)
Step-by-step explanation:
it's the only point that's both on the line and and further away from point A
Answer: If they worked together, it would take 31.5 minutes
Step-by-step explanation:
There's a certain formula for equations like this:

t1= the time it took for the first person to complete the task.
t2= the time it took for the second person to complete the task.
tb= the time it took for both of them to complete the task.
We have the values for both t1 and t2, but not for tb.
t1= 45
t2= 105
tb= x

Now it's simple algebra, and all we need to do is solve for x
The LCM for both fractions is 315, so now we multiply BOTH sides of the equation by 315.

This will simplify nicely, so now we just need to get x on the other side.

2, since 2x 1/3 is 2/3, which is less than 3/4.
An expression equivalent is 1/3 x 10
