Answer:
Step-by-step explanation:
12(n/12 = 8 + n)
n = 96 + 12n
-11n = 96
n = -96/11
Answer:
The first one is 13x and second is 2x
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
To find the maximum we need to find the vertex. We can do this by writing the equation in vertex notation by completing the square.
A(w) = -w(w - 80)
= -w² + 80w
= -(w² - 80w) = -(w - 40)² + 160
The vertex is then (40, 160) and since we are looking for the value of w it will be 40.
Answer:
60y+48
Step-by-step explanation:
Answer:
Option B) minimum value at −10
Step-by-step explanation:
we have
This function represent a vertical parabola open upward (because the leading coefficient is positive)
The vertex represent a minimum
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Divide the coefficient of term x by 2
10/2=5
squared the term and add to the right side of equation
Remember to balance the equation by adding the same constants to the other side
rewrite as perfect squares
----> function in vertex form
The vertex of the quadratic function is the point (5,-10)
therefore
The minimum value of the function is -10
