Answer:
X=2y-6
Step-by-step explanation:
Y = 1/2 X+3
Y = X/2+3
Y = X+2•3/2
Y = X+6/2
2y = X+6
2y + (-6) = (X+6) + (-6)
2y-6 = X+6-6
2y-6 = X
Answer: X = 2y-6 I hope it helps....

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x² + 10x - 6
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute: f(-5) = -(-5)² + 10(-5) - 6
- Exponents: f(-5) = -(25) + 10(-5) - 6
- Multiply: f(-5) = -25 - 50 - 6
- Subtract: f(-5) = -75 - 6
- Subtract: f(-5) = -81
