Answer:
Option A
Step-by-step explanation:
Option A
f(x) = -3(x + 7)(x + 4),
Remember that to solve for the x-intercepts we equate y to 0,
-3(x + 7)(x + 4) = 0
Using the zero product property,
x + 7 = 0, x + 4 = 0
x = - 7, x = -4
x -intercepts: (- 7, 0) & (- 4, 0)
Hence proved.
Answer:
C. (15/2,9/2)
Step-by-step explanation:
To find the midpoint of two points
midpoint = (x1+x2)/2 , (y1+y2)/2
= (17+-2)/2, (1+8)/2
= 15/2, 9/2

(-1)(-1)(-1)(-5)=
(-1)(-5)=5
Answer:
a) 50S + 30C ≤ 800
b) 1) MAX = S + C
2) Max = 0.03S + 0.05C
3) Max = 6S + 5C
Step-by-step explanation:
Given:
Total space = 800 square feet
Each sofa = 50 square feet
Each chair = 30 square feet
At least 5 sofas and 5 chairs are to be displayed.
a) Write a mathematical model representing the store's constraints:
Let S denote number of sofas displayed and C denote number of chairs displayed.
The mathematical model will be:
50S + 30C ≤ 800
At least 5 sofas are to be dispayed: S ≥ 5
At least 5 chairs are to be displayed: C ≥ 5
b)
1) Maximize the total pieces of furniture displayed:
S + C = MAX
2) Maximize the total expected number of daily sales:
MAX = 0.03S + 0.05C
3) Maximize the total expected daily profit:
Given:
Profit on sofas = $200
Profit on chairs = $100
Max Expected daily profit =
Max = (200S * 0.03) + (100C * 0.05)
<em>Max = 6S + 5C</em>
