Answer:
-9 1/5 - 10 + 2/5 + 2(14 1/2 - 7) = -3.8
Step-by-step explanation:
Answer:
x=31
y=6
Step-by-step explanation:
2x+3y=80
x+y=37
solve by elimination:( multiply second equation by 2) to eliminate x
2x+3y=80
2x+2y=74
subtract the two equations:
2x+3y-(3x+2y)=80-74
2x+3y-3x-2y=6
y=6 (3 point basket)
substitute: x+y=37, x=37-6=31
x=31 (2 point shot)
Answer:

Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0.
The derivative of
is
. The derivative of
is
, for example.
The derivative of the ln function:
If we have:

The derivative is

In this problem, we have that:

So
and 
So the derivative to this function is
