Write an equation of a line that passes through the point (3,0) and is perpendicular to the line y=−1/2x−4.

Step-by-step explanation:

perp. 2

y - 0 = 2(x - 3)

y = 2x - 6

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
