Answer:
<em>The dimensions of the area will be 8 ft x 40 ft</em>
Step-by-step explanation:
<u>Area and Perimeter</u>
The perimeter can be understood as the distance measured around a shape. The area gives us the idea of the space occupied by the shape. Being w and l the width and length of a rectangle, the perimeter and areas can be computed as follows


The dog trainer has 96 ft of fencing to cover a  rectangular area. This means that
 rectangular area. This means that


A system of equations is formed

We divide the last equation by 2

solve for w

Replacing in the first equation

Operating and arranging


We have two possible answers

Which gives us

In any case, the dimensions of the area will be 8 ft x 40 ft

Answer:
y = -20x + 100
Step-by-step explanation:
As per your requirement For Part B, the solution is 
The equation in slope-intercept form to model the relations is below:-
To reach 2 points on the graph the line passes through
lets use p1(0, 100), p2(1, 80)
now we will compute the slope:


= -20
and now use line equation in form point-slope:
y - y1 = m(x - x1)
y - 100 = -20(x - 0)
y = -20x + 100
 
        
             
        
        
        
Answer: Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values,  and
 and  , that have the same output value y
, that have the same output value y
Note that the function  is not a one-to-one function
  is not a one-to-one function
When x=2  
When x=8  
Note that the function  is not a one-to-one function
  is not a one-to-one function
When x=1 
When x=-1  
Note that the function  is not a one-to-one function
  is not a one-to-one function
When x=1 
When x=-1  
Then the answer is the option B.
You can verify that The function  is a one-to-one function and therefore its inverse is a function
 is a one-to-one function and therefore its inverse is a function
 
        
             
        
        
        
Answer:
Bianca's height = 42 inches
Step-by-step explanation:
Let x be the Bianca height.
Given:
Meredith height = 60 inches
We need to find the Bianca height.
Solution:
From the given statement the Meredith's height is  of Bianca's height plus 32 inches, so the equation is.
 of Bianca's height plus 32 inches, so the equation is.
Meredith's height = 
Substitute Meredith's height in above equation.

Now we solve the above equation for x.


By cross multiplication.

28 divided by 2.
 
 

Therefore, the height of the Bianca is 42 inches.
