<h2>
Answer:</h2>
is 3 ohms
<h2>
Step-by-step explanation:</h2>
In a circuit containing two resistors
and
connected together in parallel, the total resistance
is given by;
---------(i)
<em>Make </em>
<em> subject of the formula;</em>
=>
=> 
=>
---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=> 

= 3Ω
Therefore, the value of
= 3 ohms or
= 3Ω
Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
You substitute the y from the second eqaution to the y in the first equation
Well the remainder more possible dividing by six would be 9.3 I hope i helped.
