A quadratic equation is shown below:
x2  8x + 13 = 0
Which of the following is the first correct step to write the above equation in the form (x  p)2 = q, where p and q are integers?
Subtract 5 from both sides of the equation
Subtract 3 from both sides of the equation
Add 5 to both sides of the equation
Add 3 to both sides of the equation

Best ResponseYou've already chosen the best response.1do you know how to complete the square? let's practice do you think x^22x+1 can be written as a square?

Best ResponseYou've already chosen the best response.1can you write is as a square for me?

Best ResponseYou've already chosen the best response.1okay so if you do that then we have x^28x+13+3=0+3 x^28x+16=3

Best ResponseYou've already chosen the best response.1so are you think x^28x+16 can be written as square?

Best ResponseYou've already chosen the best response.1can you find the vertex for the first one?

myininaya

Best ResponseYou've already chosen the best response.1now the vertex is very important for consider the min or even the max for a parabola that is why i asked for the other graph i think a good way to approximate the vertex is just plot those points given

Best ResponseYou've already chosen the best response.1i want you to speculate on what you think the vertex is

myininaya

Best ResponseYou've already chosen the best response.1now it helped me to actually plot the points so i encourage you to do so

Best ResponseYou've already chosen the best response.1tell me what you think looks like the middle point of that graph

myininaya

Best ResponseYou've already chosen the best response.1now the y values for each of these points is the amount of min production cost from each graph

myininaya

Best ResponseYou've already chosen the best response.1aka lowest y value for each graph

myininaya

Best ResponseYou've already chosen the best response.1the question ask you to compare the y values basically it ask which one is greater

myininaya
 11 months ago
Best ResponseYou've already chosen the best response.1right because 899.5>55 so company 2 has a bigger min production cost
