Answer:
Answer:
f(x) = - 4x + 4
Step-by-step explanation:
Step-by-step explanation:
A linear function has the form
f(x) = ax + b, thus
f(0) = a(0) + b = 4, that is
0 + b = 4 , hence b = 4
f(3) = 3a + b = - 8 ← substitute b = 4
3a + 4 = - 8 ( subtract 4 from both sides )
3a = - 12 ( divide both sides by 3 )
a = - 4, thus
f(x) = - 4x + 4
 
        
             
        
        
        
<h2>x = 1/4</h2><h2>y = -2</h2><h2>______________</h2>
<h2>Known : </h2>
 y = -8x 
4x - y = 3 
<h2>Asked: </h2>
Use the substitution method to solve the system of equations ?
<h2>Answered:</h2>
<h3>Substitution y</h3>
 4x - y = 3 
 4x - (-8x) = 3
 4x + 8x = 3
 12x = 3
 x = 3/12
 x = 1/4
<h3>
Substitution x</h3>
 4x - y = 3 
4(1/4) - y = 3
 4/4 - y = 3
 1 - y = 3
 -y = 3 - 1
 -y = 2
 y = -2
