Answer:
<u>40°</u>
Step-by-step explanation:
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:
C. y = 600x + 2200
Step-by-step explanation:
2800-2200 = 600 = slope
2200 (y value) has the x value 0, so 2200 is the y-inercept
hope this helps :)
True: adding two polynomials will always result in another polynomial
Answer:
720
Step-by-step explanation:
Since there are six coordinates, the polygon must be a hexagon.
Sum of angles in a polygon= (n-2)×180
= (6-2) × 180
= 720
