Answer:
<em>The rate of the equation is r when r is a constant</em>
Step-by-step explanation:
We need to solve for the rate of the equation
d = rt
Differentiating on both sides with respect to time
= 
Considering r as a constant
= r×
where,
= 1
= r
<em> The rate of the equation is r when r is a constant</em>
<em> </em>
Answer: x = 14/23
Step-by-step explanation:
3x-6=4(2-3x)-8x
3x-6=8-12x-8x --> Expand 4(2-3x)
3x-6=8-20x --> Collect like terms
3x-6+6=8-20x+6 --> Add 6 to both sides, to remove it from the right side
3x=-20x+14
3x+20x=-20x+14+20x --> Add 20x to both sides, to remove it from the left side
23x=14
--> Divide both sides by 23
x = 14/23
We are given the following function:

We are asked to do the following tranformations:
1. Shift down 5 units and left 77 units.
First, to shift a function down a number "n" of units we follow the next rule:

And, to shift a function "m" units to the left we use the following rule:

Applying both rules simultaneously we get:

2. Reflect about the y-axis.
The rule to reflect a function about the y-axis is the following:

The means that we will change "x" for "-x" in the function we are going to reflect. Applying the rule we get:

3. Compress vertically by a factor of 2.
To compress a function vertically by a factor "m" we multiply the entire function by 1/m, like this:

Applying the rule we get:

And thus we get to the final function.
