Step-by-step explanation:
Let x be the required number of hours for which the total fee charged by the companies the same.
Given: Peppy Pets charges a flat fee of $15 plus $3 per hour .
So Total charge = 15+3x ( in dollars)
Happy Hounds charges a flat fee of $21 plus $1 per hour.
So Total charge = 21+x ( in dollars)
When the total charge for both companies are the same, then
Hence, the correct option is d) 3 hours.
Answer:
x = -1 ± √3
Step-by-step explanation:
3x² − 2x − 1 = x² − 6x + 3
Move everything to one side.
2x² + 4x − 4 = 0
Divide by 2.
x² + 2x − 2 = 0
Solve with quadratic formula, or by completing the square.
x² + 2x = 2
x² + 2x + 1 = 3
(x + 1)² = 3
x + 1 = ±√3
x = -1 ± √3
