Hope that helps? Sorry if it doesn’t...
(-5, 0) and (-1, 0) are the solutions of -2(-x - 3)² + 8 = 0
Step-by-step explanation:
- Step 1: Find the solutions of -2(-x - 3)² + 8 = 0.
Solutions are the intersecting points of y = -2(-x - 3)² + 8 and y = 0.
⇒ Solutions are (-5, 0) and (-1, 0)
- Step 2: (-5, 0) and (-1, 0) are solutions of -2(-x - 3)² + 8 = 0
Answer:
y = 9 - 3x
Step-by-step explanation:
9x + 3y - 27 = 0 ( add 27 to both sides )
9x + 3y = 27 ( subtract 9x from both sides )
3y = 27 - 9x ( divide through by 3 )
y = 9 - 3x
