1. The following are examples of polynomials, EXCEPT a. x2 - 4x + 5
c. 3x4 -5x + 2x - 1
b. 4x3 + 8x2 + 10x - 7
d. x- y

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∣∣

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

This is about circle theorems. someone asap : (
