Radar indicates a car is traveling at 90 miles per hour. how fast is the car traveling in kilometers per hour? (use this conversion formula: 1 mile = 1.609 kilometers)

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

How far is x from 5 on a number line?

Sorry guys but as you have a small brain
