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
Answer:
5
Step-by-step explanation:
6x-2 = 56°/2
6x-2 = 28
6x = 28+2
6x = 30
x = 5
Answer:
y = -7x + 16 and y = -2x - 9
Step-by-step explanation:
Of the five equations the only ones that exist at the point, (5, -19) are y = - 7x + 16 and y = -2x - 9 (Test them out yourself!).
Hope this helps :)
