Answer:
1. X= 56
2. X= -11/2 (When you solve you get this if you need it as a mixed number it's X= -5 1/2
Step-by-step explanation:
simplifying  means: Reducing to lowest terms.
To solve for  x  simplify both sides of the equation, then isolate the variable.
 
        
             
        
        
        
Answer:
y=(5/4)x-5/4
Step-by-step explanation:
First we need to find the slope:

=
=5/4
The SLops is 5/4
point-slope forum is
y=(5/4)x-5/4
(i think)
 
        
             
        
        
        
3.2 is the answer.

The answer is: 12 centimeters.
 The explanation is shown below:
 1. By definition, all four sides of the square are equal and the diagonals are equal too. 
 2. Keeping the information above on mind, you know that AC and BD are equal:
 
 3. Then, the length of BD is twice BE. So, you can calculate it as following:
 
 
 4. Therefore, the lenght of AC is:
 
 
        
             
        
        
        
Answer: the x-intercept is (-10,0), the y-intercept is (0,45/2)
Explanation: 
First, we need to determine the function describing the line. 
From the table, it is obvious that the y values increase by 9 every increase of 4 of the x values. So, the slope is 9/4 and the function looks like this:

with the y-intercept (or bias) b still unknown. This can be determined by using one of the point from the table, like so:

The above function form makes it easy to read off the y-intercept, which is (0,45/2) or (0,22.5). The x-intercept is obtained by setting y = 0 and solving for x:

The x-intercept is (-10,0)
