Three different relationships between proportional quantities x and y are being described in the parts below. (look at the photo)

If each relationship is graphed with the same scale, then which graph will be the steepest?

Which graph will be the least steep?

choose a b or c

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2

Order the equations from least to greatest based on the number of solutions to each equation.-4^x -1 = 3^(-x) – 2 -3x + 6 = 2^x+13^x – 3 = 2x - 2
