Answer:
-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
Hello!
This question is about which values you are changing when you are transforming an equation.
Let's go through the parent function for an absolute value equation and its various transformations.

Since we are only looking at horizontal and vertical transformations, we only need to worry about the c and d values.
The c value of a function determines a function's horizontal position, and the d value of a function determines a function's vertical position.
One thing to note here is that the c value is being subtracted from the x value, meaning that if the function is being transformed to the right, you would actually be subtracting that value, while the d value behaves like a normal value, if it is being added, the function is transformed up, and vice versa.
Now that we know this, let's write each expression.
a) 
b) 
c) 
d) 
Hope this helps!
If in 2000 there were 430 folksk, 2010 is 10 years later, thus t = 10
Answer:
250 square feet
Step-by-step explanation:
This problem can be easily solved using ratios.
It says that
pound covers 375 sq. ft.
So, how much would 1 pound cover?
Let 1 pound cover "x" pounds. We can setup up two ratios and equate them. Then cross multiply and solve for x.
Note: Pounds on numerator and Square Feet on denominator

Hence, 1 pound of wildflower seeds will cover an area of 250 square feet
