In 1998 there were 305 students who graduated from high school. In 2019, there were 356 students. What is the rate of change in the number of students? 1. About 1 student per year
2. about 51 students per year
3. about 2 students per year
4. about 5 students per year

3. about 2 students per year

Step-by-step explanation:

The rate of change would be the difference in the number of students divided by the number of years passed.

So, rate of change =

=

So it's around 2 students per year.

I hope this is correct and helps!

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

good luck on ur quiz test or homework. have a good day : )
