Answer:
The answer is letter A.
Step-by-step explanation:
y=mx+b
-3=(-1)(0)+b
-3=0+b
0 0
-3=b
y= -1x-3
Answer:
the slope is 0
Step-by-step explanation:
You first do -9--9 and then divide 14-8
It will be 0.073. because the 73 is in the 1000 place
The answer to your question is
f(x) =x(x+1)^2 (x-1)
Price elasticity is defined as

.
Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0
We calculate

by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)
Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)
