Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
Answer:
AB = 4
Step-by-step explanation:
Since the line is horizontal then its length is the difference of the x- coordinates, that is
AB = | 8 - 4 | = 4 , or
AB = | 4 - 8 | = | - 4 | = 4
7+49n-63 that is the answer to the question
R= 40
pr!(5,r)= 40
hope this helps
X + y = 6 does NOT demonstrate direct variation, because the graph of this line does not go through the origin (0,0).
y-x=0, or y=1x, DOES demo direct var. The graph goes through the origin.
