1. Explain what positive and negative intervals are and how you find them in a table or a graph. 2. Explain how to find a positive and negative interval when given an equation.

3. Explain what increasing and decreasing intervals and maximum and minimum are and how you find them in a table or a graph.

4. Explain how to find an increasing and decreasing intervals and maximum and minimum when given an equation.

5. Explain the differences between a positive interval versus an increasing interval and a negative interval versus a decreasing interval.

just took the test and my answers down below!

step-by-step explanation:

check the pic :

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
