What is the Hodge conjecture? also plz solve this plz: (a^2 + b^2)/(ab + 1)
plz dont report this cause of the pics. i actually need to know this.

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∣∣

Read the equations in the table below. then drag a description of the situation and a table to represent each equation. indicate whether each of the relationships is proportional or non-proportional.

What’s the answer ? use the picture to see the problem
