Answer:
no
Step-by-step explanation:
y = –5x + 4
Substitute the point into the equation
0 = -5(4) +4
0 = -20+4
0 = -16
This is not true so it is not a solution to the equation

Answer:  a = ¹/₂ (4 + b)</h2>
<h3>
Step-by-step explanation:</h3>
To solve for 'a' we have to make it the subject of the equation. Since there are two unknowns ('a' & 'b'), we won't get a numerical value of 'a', but an expression in terms of the second unknown 'b'.
Since 2a - b = 4                    <em> [add 'b' to both sides]</em>
then          2a = 4 + b             <em>[divide both sides by 2 = multiplying by  ¹/₂]</em>
                    a = ¹/₂ (4 + b)
 
        
        
        
The greatest common  factor of 8,27,35 is 1.
