Answer:
x=y+20
Step-by-step explanation:
y=x-20
Swap sides so that all variable terms are on the left hand side.
x-20=y
Add 20 to both sides.
x=y+20
We can get the Profit function P(x) from the Hint.
the Profit function is: P(x) = xp(x) - C(x) = -0.00041 x2 + 4x - 600
Attention: don't get confuse by the <span>big P of the profit with the small p of the price</span> To calculate the maximum profit, we need to find the derivative of P(x) then set it to 0 then find x: dP(x)/dx = -0.00082 x + 4 = 0 , so x = 4/0.00082 = 4,878 copies each month.
Your answer is the first choice,
x = 9/2
Hope this helped! (:
Hey mate,
We have,
st²-pqr
Given values,
p= -2,q=5,r= -7,s=0 and t=4
On substituting,we obtain:
→(0)(4)²-(-2)(5)(-7)
→16-(70)
→16-70
<u>→</u><u>-</u><u>5</u><u>4</u>
Answer:
Step-by-step explanation:
y= -5(10) + 30
y = -50 + 30
y = -20
x= 10
(10,-20)
this is the solution
