Answer:
x = -7.5
Step-by-step explanation:
P = 600 + 1,500x − 100x^2
P = − 100x^2 + 1,500x + 600
x = -b/2a
1500/ (2 x -100)
x = -7.5
Answer:
-12
Step-by-step explanation:
First, solve in parentheses.
2(-2-4)
=
2(-6)
Next, multiply 2 by -6.
Which equals -12.
So therefore using the distributive property shown above, the answer would be -12.
Answer:
Vertex: (5, -9)
Step-by-step explanation:
fix = (x-8)(x-2)
fix = x^2 - 2x - 8x + 16
fix = x^2 - 10x + 16
a = 1, b = -10, and c = 16
To find vertex:
x = -b/2a
x = -(-10)/2(1)
x = 10/2
x = 5
y = 5^2 - 10(5) + 16
y = 25 -50 + 16
y = -9
Vertex: (5, -9)
Answer:
Step-by-step explanation:9 1/2 cups / (1/4 cups/bowl) = 19/2 cups x 4 bowls/cup = 76/2 bowls = 38 bowls. QED.
