Answer:
Step-by-step explanation:
The question is not terrifically worded. What it means is "What is the y value when x = 8" That's what f(8) conveys to you.
The answer (though zero is not marked and should be) is 1 unit above 0.
The answer is f(8) = 1 He's heading back.
To prove that x = 2 in the equation given, first, we write the given.
(4) Given: (A) 12 - x = 20 - 5x
Then, add 5x to both sides of the equation,
(3) Addition property of equality: (B) 12 + 4x = 20
Then, subtract 12 from both sides of the equation
(2) Subtraction property of equality: (C) 4x = 8
Lastly, divide both sides by 4
(1) Division property of equality : (D) x = 2
