The table below shows the amount of a radioactive compound remaining after X years Sarah is compiling the data into a lab report
including a graph and needs to determine what scale to use which statement is true about her data.
A. the y-intercept of the graph is 900, and the X increases, f(x) approaches 100.
B. the amount of radioactive substance will continue to Decay at a constant rate over time until it reaches the x-axis.
C. the y-intercept of the graph is 900, andaz x increases, f(x) approaches infinity.
D. the x-intercept of the graph is 900, and as X increases, f(x) approaches 100.

Answer:
Step-by-step explanation:
It must end in (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is .
We want to make as low as possible because it's a higher digit than
.
If is as low as possible, we have that the sum is
. Uh-oh.
has to be even! So
doesn't work.
If , we have that the sum is
. Yay!
So, the answer is
