y= x2 + 8x - 1 is y=(x+4) 2-17
Step-by-step explanation:
First find - b/2 = - 4, so -4 will be added to x inside the parenthesis.
Next , find c - b2 to find the value you added at the end
y= (x- b2) 2 + c - b2
y= (x+4) 2 - 17
Answer:
No
Step-by-step explanation:
Please write: "Determine whether y+x=1 shows direct variation."
No, it does not, because of the constant term, 1.
If we were to eliminate the 1 and write y + x = 0, then yes, this would represent direct variation.
