Answer:
The answer to your question is Katie had 15 rocks and Oliver 45 rocks.
Step-by-step explanation:
Conditions
Katie has x amount of rocks
Oliver has 3x amount of rocks
The final amount of rocks
Oliver = 3x + 75
Katie = x + 105
Now, they have the same amount of rocks, then we can equal both equations
3x + 75 = x + 105
Solve for x
3x - x = 105 - 75
2x = 30
x = 30/2
x = 15
Conclusions
At first Katie had 15 rocks and Oliver had 3(15) = 45 rocks
So you’ll take $11.50-$4.75=$6.75 then you’ll divide this answer by 3 6.75/3=2.25 so it was $2.25 per movie to rent
Answer:
Well, the function is F(x)=x^(2)-6x=C so the domain would be found infinite.
All of the numbers are real except where the expression is undefined but in this case, there is no real number that makes the expression undefined.
Hope this helped, if not, message me and I'll try to explain further.
