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

can you write is as a square for me?

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

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

now 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
 5 months ago

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

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

that is very great

now the y values for each of these points is the amount of min production cost from each graph
 5 months ago

myininaya Group TitleBest ResponseYou've already chosen the best response.1
aka lowest y value for each graph
 5 months ago

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

kristinak Group TitleBest ResponseYou've already chosen the best response.2
company 2?
 5 months ago

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