Perpendicular to y=3x5; passing through the point (-6,-4)

You and a friend race across a field to a fence and back. your friend has a 50-meter head start. the equations shown represent you and your friend's distances dd (in meters) from the fence tt seconds after the race begins. find the time at which you catch up to your friend. you: d=∣−5t+100∣d=∣−5t+100∣ your friend: d=∣−313t+50∣∣

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

Do,h = (7, 9) (14, 18) the scale factor is
