Answer:
Step-by-step explanation:
The derivative of an addition/subtraction of terms is the addition/subtraction of the derivatives of these terms.
The derivative of a constant is 0.
The derivative of 
is 
. The derivative of 
is 
, for example.
The derivative of the ln function:
If we have:
The derivative is
In this problem, we have that:
So 
and 
So the derivative to this function is
Step-by-step explanation:
the relationship between x and y is defined by a constant factor.
you can "go" from x to y and from y to x consistently and without any interruptions by applying that constant factor.
that makes it a linear relationship (a line on a chart, hence the name).
proportional relationships are relationships between two variables where their ratios are equivalent. another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
so, yes, it is proportional.
and the table is then
x y
0 0
3 3×2/3 = 2
6 6×2/3 = 4
9 9×2/3 = 6
Answer: The answer is -15/7
Step-by-step explanation: Think of the 3 as 3/1. You then have the equation as -5/7 x 3/1. Multiply straight across so it would be 5 x 3 and -7 x 1. It doesn't matter what you do with the negative as long as it is in the final answer. It could be in the denominator or the numerator. So that answer is -15/7.

Answer:
Devin will donate <u>$67.5</u> to charity.
Step-by-step explanation:
Given:
Devin made 30 custom t-shirts to sell.
He will donate 1/8 0f his total sales to a local charity.
He sold all 30 t-shirts for $18 each.
Now, to find the amount Devin donate to charity.
Total number of t-shirts = 30.
Each t-shirts sold at = $18.
So, total amount of 30 t-shirts sold:
As, Devin will donate 
of his total sales to a local charity.
Now, to get the amount he will donate to charity:
Therefore, Devin will donate $67.5 to charity.
