Answer:
The graph increases then decreases
Step-by-step explanation:
If you look at point G it is increasing until it gets to the x value of 0. From there on it is decreasing to K.
Answer:
$57
Step-by-step explanation:
$380x0.85=$323
$380-$323=$57
Answer:
price = $190
quantity = 950 tickets
Step-by-step explanation:
revenue = price * quantity
n = number of $10 price reductions
price = 300 - 10n
quantity = 400 + 50n
r = (300 - 10n)(400 + 50n)
recognize these as the factors of a quadratic that opens down
the vertex will therefor be the maximum revenue
the roots are:
300 - 10n = 0
300 = 10n
n = 30
400 + 50n = 0
50n = -400
n = -8
vertex is at mid point of the roots
n = (-8 + 30)/2
n = 11
price = 300 - 10n
price = 300 - 10(11)
price = 190
quantity = 400 + 50n
quantity = 400 + 50(11)
quantity = 950
Answer:
From the origin , move 3 units to the right and 2 units up. B
The answer is Y=11, X=-1
Here's my work:
x=-12+y
-6(-12+y)+2y=28
6*12= 72
72 -6y +2y=28 (now we combine like-terms)
72-4y=28 (now divide by -4)
-18+y=-7 (add 18 to both sides)
y=11
next part we find x:
x=-12+(11)
x=-1
