We can complete the square to get a standard form quadratic into vertex form. First, add Y and 34 to the right side of the equation. You’ll get -5x^2 + 30x = y + 34.
Next, you need to factor out a -5 from the left side, so you’ll get -5(x^2 -6x) = y + 34. Then, complete the square on the left. You’ll get -5(x-3)^2 = y - 11. Finally, add 11. The answer is y = -5(x-3)^2 + 11

Answer: Marci: 60 minutes
Bobby: 30 minutes
Max: 90 minutes
Step-by-step explanation:
50% of 60 is 30.

27.5 and 22.5 are the two numbers
Answer:
Step-by-step explanation:
3x + 3y = -3 given
3x = -3y - 3 subtract 3y from both sides
x = -y -1 divide everything by 3
hope this helps <3
