Answer:
-1.1, 6.1
Step-by-step explanation:
-2X^2+10X+14=0
(-2X^2+10X+14)/-2=0
X^2-5X-7=0
Then use the quadratic formula because you can't factor
Fill in the equations and solve. One should have the plus and the other should have the minus and that's how you get the 2 different answers.
A=1
B=-5
C=-7
Use a calculator
Just look up how to find unit rates and it should be easy
Answer:
you would receive 12.5% of the discount
Step-by-step explanation:
20% off of 62.50 is 50; so you would pay $50
Answer:
a) $50,880
b) $48
c) 1060
Step-by-step explanation:
a)
-320x^2 + 1920x + 48000 = 0
This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)
x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3
The maximum revenue, y, is the value of the function evaluated at x = 3.
f(x) = -320x^2 + 1920x + 48000
f(-3) = -320(3)^2 + 1920(3) + 48000
f(-3) = 50,880
The maximum revenue is $50,880
b)
Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48
c)
$50,880/$48 = 1060
