(x1,y1)=(0,6)
(x2,y2)=(6,0)
slope=(0-6)/(6-0)=0
Answer:
The answer is D. Hope this helps!
Answer:
165 cards left
Step-by-step explanation:
x + 221 = 386
-221 from both sides
x = 165
Answer:
A) The model exists: f(x) = -3x^2 +4x -4
Step-by-step explanation:
A quadratic model will always exist for 3 given points, provided they are not on a line. In that case, a linear model is appropriate.
Here, the slope between -1 and 0 is positive, and the slope between 0 and 3 is negative. Thus, we know these points are not collinear, and a model must exist.
The model is most easily found using a quadratic regression tool. Such is shown in the attachment. It tells us that ...
f(x) = -3x^2 +4x -4
