Answer:
y = -4/5x + 4
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define</u>
Standard Form:   4x + 5y = 20
<u>Step 2: Rewrite</u>
- Subtract 4x on both sides:                    5y = 20 - 4x
- Divide 5 on both sides:                          y = 4 - 4/5x
- Rearrange:                                              y = -4/5x + 4
 
        
             
        
        
        
By the Pythagoras theorem:-
h^2  = x^2 + x^2   
    (where h = hypotenuse)
h^2 = 2x^2
h = sqrt2 x
        
             
        
        
        
Answer- 86 and 49
Step-by-step explanation: 86+49=135
                                               86-49=37
 
        
             
        
        
        
Answer:
0
Step-by-step explanation:
Assuming the six sided dice are numbered 1 through six
The max each could roll is 6
6+6 = 12
They cannot reach a sum of 13
