So first off, the answer to this is 24 now think of x as the  real or original sum or amount, also y as the new sum or amount.
y * 1.5 is x, and y+12 is x. Now flip that to figure out what is y, also which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to minus 12, which can help you get the answer which is 24.

Let's first take a look at function G. From the first to second row, the x-value increases by 2, and the y-value increases by 8.

Thus, function G has a rate of change of 8/2, or 4.

In function H, there is a "2" before the "x", which means function H has a rate of change of 2.

Thus, the statement that is true is:

  • Function G has a rate of change of 4, and function H has a rate of change of 2

Let me know if you need any clarifications, thanks!
