<h2>
Answer: Line 1 should be x = y² + 12y NOT (x = y² + 12 x)</h2>
<h3>
Step-by-step explanation:</h3>
solving for the inverse of y = x² + 12x
Line 1: x = y² + 12 x.
Line 2 y² = x - 12 x. <em> </em>
Line 3 is y²= - 11 x.
Line 4 is y = √(- 11x) for x ≥ 0.
The error lies in Line 1. All x's have to be switched with y's and vice versa for the method to work.
As such Line 1 should be x = y² + 12y NOT (x = y² + 12 x)
Since Line one is wrong, it messes with all the other lines.
Answer:
27
Step-by-step explanation:
Let's set this up as an equation.
We know that dividing with exponents means we subtract the exponents. 15-12 = 3.
