Quadrilateral ( trapezoid )
        
             
        
        
        
Answer:
look at analysis 
Step-by-step explanation:
11. 23.81
12.
part A 
y is 12 and x is 4
part B 
4
part C
5×12×4
240
 
        
             
        
        
        
You need to find what x is equal to for each equation, so you can sub why x is equal to in the place I'd x to eliminate the variable 
1. 6x-5y=-4
6x=5y-4
X=5/6y-2/3
2. 4x+2y=28
4x=-2y+28
X=-1/2y+7
Hope this helps!
        
                    
             
        
        
        
Answer:
yes
Step-by-step explanation:
5(8y-8) = 5*8y - 5*8 by distributive property. simplify that, you get 40y-40, which is equal to 40y-40.
I hope this helped, please give brainliest if this is correct! Thank you!
 
        
             
        
        
        
Answer:
A. y = 80x
B. g(x) = 80x
C. To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
Step-by-step explanation:
Part A:  
To write an equation, use y= mx where m is the slope, x is the number of days, and y is the rent cost.
x and y remain the same in the equation.
To find m, use the slope formula with (5,465) and (7, 625).

It costs $80 a day.
The equation is y = 80x.
Part B:  
Function notation replaces Y as g(x). So the equation is g(x) = 80x.
Part C:
To graph the equation, plot a point at (0,0) and a point at (1,80). Connect the points. Continue adding points by moving up $80 and over 1 day.
