The time that elapses until half the element remains is__ years. It is expecting me to use Intersect on a graphing calculator to find the answer. The example for this problem says to use y sub 2=0.5, I found the function to be y=32-22e^-0.066890232x
(x is the t in the half life formula). I hope I am correct on this. I don’t k on how to find the half part of the graph and I tried using a graphing calculator online. Thanks for the help!

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
