Answer:
the answer would be:
3 (t+2)
Step-by-step explanation:
$1.75 + $0.25x <span>≤ $15; x < 53
So the first one. Because you must pay the flat fee, and then for x miles you must pay $0.25. When you do (15-1.75) / 0.25 the answer is 53.</span>
Solutions to the equation are 5, -6
Step-by-step explanation:
- Step 1: Equation is √(x² + 2x - 25) = √(x + 5). Square both sides to simplify the equation
⇒ x² + 2x - 25 = x + 5
⇒ x² + x - 30 = 0
⇒ x² + 6x - 5x - 30 = 0
⇒ x(x + 6) - 5(x + 6) = 0
⇒ (x - 5)(x + 6) = 0
⇒ x = 5, -6
Distribute through the parentheses
Cancel equal terms on both sides of the equation Divide both sides of the equation by and it would be x=1
