Answer:

  x ∈ {-3, 1.2, 1.25}

Step-by-step explanation:

"Solve" is non-specific as to the solution required. We assume you want the x-intercepts.

A graph shows the zeros to be ...

  • x = -3
  • x = 1.2
  • x = 1.25

The equation can be factored as ...

  y = (1/2)(x +3)(4x -5)(5x -6)

What is the distance between the points (5,5) and (2,9)? Question 3 options: 5 units 25 units 36 units 6 units
aleksklad [387]
Use distance formula:

d = √( (x₁ - x₂)² + (y₁ - y₂)² )

Here you have x₁ = 5, x₂ = 2, y₁ = 5, y₂ = 9

So that would be √( (5-2)² + (5-9)² ) = √( (3)² + (-4)² ) = √(9+16) = √25 = 5

Final answer: 5 units
