Answer: The answers are
(i) The local maximum and local minimum always occur at a turning point.
(iii) The ends of an even-degree polynomial either both approach positive infinity or both approach negative infinity.
Step-by-step explanation: We are given three statements and we are to check which of these are true about the graphs of polynomial functions.
In the attached figure (A), the graph of the polynomial function 
is drawn. We can see that the local maximum occurs at the turning point P and local minimum occurs at the turning point Q. Also, the local maximum is not equal to the x-value of the coordinate at that point
Thus, the first statement is true. and second statement is false.
Again, in the attached figure (B), the graph of the even degree polynomial 
is drawn. We can see that both the ends approaches to positive infinity and in case of 
, both the ends approch to negative infinity.
Thus, the third statement is true.
Hence, the correct statements are first and third.
Answer:
9)x=11 y=3
11)x=18 y=5
Step-by-step explanation:
9) 9x+25=13x+19 13x-19+17y+5=180
9x+44=13x 129+17y=180
44=4x 17y=51
11=x y=3
11) 49+3x=7x-23 3x=11y-1
Answer:
Time for a round trip = 12.5 hours
Step-by-step explanation:
Mother's house = 250 miles
Total distance for the round trip = 250 + 250 = 500 miles
Given speed = 40 mph
<em><u>Find time .</u></em>

It depends on the shape it may be rotation
Answer: 34 degrees
Step-by-step explanation:
The starting temperature was -5 degrees at 5am, and after two hours, the temperature was 34 degrees at 7am. The temperature increased by 39 degrees, how did we get this answer?
You add -5 and 39
-5 + 39 = 34
A tip for adding negatives:
When you get a problem similar to -5 + 39, you can actually flip them around if you need an easier understanding. So it would be 39 - 5. Both equations still equal 34 as long as you keep the values of each number!
