Answer:
a. 4
b. -8
c. -2
Step-by-step explanation:
Take any number x;
Its opposite is -x
The opposite of its opposite is x
Using the above statements, we can solve the following questions
Solving (a): -4
In this case:

The opposite; -x is


Solving (b): 8
In this case:

The opposite; -x is

Solving (c): -2
In this case:

The opposite; -x is


The opposite; -(-x) is


Answer:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. If they are inversely proportional, an increase in the value of one variable would cause a corresponding decrease in the other variable.
Looking at the given values, as x is increasing, y is also increasing. The constant of proportionality is
9/3 = 27/9 = 3
Therefore, the relationship is a direct variation and the function to model it is
y = 3x

Answer:
15.3 m/s
Step-by-step explanation:1) Find the gravitational potential energy using the equation :


2) Then use the equation for kinetic energy to solve for the velocity:


It's been such a long time, but I think (1) should be the addition property since your adding 5 to both sides.
And (2) should be the multiplication property due to multiplying both sides by 2.
