Hi there!

So first off, here are little definitions you need to know in order to be able to answer your question :

Constant means that the rates of change are the same.

Variable means that the rates of change are different.

But from what I can see, you don't even need those definitions because you got both answers right!

Continue your great work! If there's anything just let me know! :)

Describe what happens when two intersecting lines form a linear pair of congruent angles. Explain how you can get eight congruen

Charra [1.4K]

The angles diagonally opposite each other are congruent while those adjacent to each other add up to 180 degrees. You can get eight congruent angles with a transversal if the two lines are parallel, because each angle would be 90.

A number line is shown. Which expression represents the distance between two points, X and Y, on the number line?

IrinaK [193]

Answer: C. |-4 - 3|

Step-by-step explanation:

x = -4

y = 3

The distance between them is the difference. The mathematical operation for difference is subtraction.

Distance is a unit of measurement. Measurements cannot be negative so the absolute value sign is used to ensure the difference is positive.

Help, will give brainlist!!

Answer:

Fred.

Started hang gliding at a height of 700 ft and descends 15 feet every seconds

Gene

Started hang gliding at a height of 575 ft and descends 10 feet every seconds

Step-by-step explanation:

The function that models Fred's hang gliding is $f(x)=-15x+700$

The initial value is 700 feet. This Fred was 700 feet above see level before he starts descending.

The rate of descent is -15 ft/s. This means Fred descends 15 feet in one second.

From the table the initial height is 575 ft. This means Gene was 575 feet above sea-level at the beginning of the hang gliding.

The rate of descent is $\frac{565-575}{1-0} =-10$ ft/s.

This means that in every seconds, Gene descends 10 feet.
