Thus, Yuri made 947 more copies than Nathan.
Answer:

Step-by-step explanation:
We have been given the following expression;
-13/√x
In order to rationalize the denominator, we multiply the numerator and the denominator by √x;

Well 8 divided 4 equals 2 so it is 2 hours.
Answer:
f(x)= -(x+1)^2 -2
Step-by-step explanation:
f(x)=(x-h)^2 +k; (h,k)
Then you would substitute the x and y of the coordinate and solve.
-6= -(1+1)^2 -2
-6= -(4) -2
-6 = -6
