Answer:
between x=-1.5 and x = 0
between x = 0 and x = 1.5
Step-by-step explanation:
For the interval -1.5 < x < 1.5, we can see that the slope is negative (i.e from top left to bottom right). Hence it can be said that the graph is decreasing during this interval.
For the other parts of the graph (as shown) the slope is positive (i.e from bottom left to top right). in those areas, the graph is increasing.
Answer:
6
Step-by-step explanation:
-X+11=-2X-7
11=3X-7
18=3X
18/3= 6
Answer:
1. JMN is perpendicularly bisected
2.JMK and JKN are right triangles
3.∠JKM is a right angle
4. ∠1 and ∠2 are complementary
Step-by-step explanation:
1. Reasoning: Given
2. Reasoning: Definition of a perpendicularly bisected triangle.
3. Reasoning: Definition of a right triangle
4. Reasoning: Triangle Sum Theorem.
Explanation of 4: Because of the Triangle Sum Theorem, which dictates the interior angles of a triangle add up to 180, the other two angles have to add up to 90 or face violating the theorem. Angles that add up to 90 are complementary.
