I think I get 2 and 4, for that one. I think you are supposed to make up an equation, such as xy ≤ x²
Answer:
288

Answer:
{4, - 1}
Step-by-step explanation:
Given
2y² - 6y - 8 = 0 ← in standard form
with a = 2, b = - 6, c = - 8
Using the quadratic formula to solve for y
y = ( - (- 6) ± ) / (2 × 2)
= ( 6 ± ) / 4
= ( 6 ± ) / 4
= ( 6 ± 10 ) / 4
x = = = 4
OR
x = = = - 1
Solution is { 4, - 1 }
Find the lcm of 7 and 5.
7: 7, 14, 21, 28, 35,
5: 5, 10, 15, 20, 25, 30, 35
so they got to see each other every 35 days.
It would be an open answer
