I CAN HELP YOUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!1
lets distribute 7(x+3)
so 7(x)+7(3)
7x+21 or b
yay :)
You will need to run around 10 times because 3000m is 3km and 300*10 is 3000 :) i hope i helped
Answer:
14
Step-by-step explanation:
11 - n = -3
-n = -3 - 11 = -14
n = 14
OR
add n to both sides of equation and add 3 to both sides of equation:
11 - n + n + 3 = -3 + n + 3 ----> n = 14
Answer:
- Let p be the population at t be the number of years since 2011. Then,
![p=2000-50t](https://tex.z-dn.net/?f=p%3D2000-50t)
- The projected population of the high school in 2015=1800
- In <u>2019</u> the population be 1600 students
Step-by-step explanation:
Given: The population at Bishop High School students in 2011 =2000
Also, Every year the population decreases by 50 students which implies the rate of decrease in population is constant.
So, the function is a linear function.
Let p be the population at t be the number of years since 2011.
Then, ![p=2000-50t](https://tex.z-dn.net/?f=p%3D2000-50t)
So at t=0, p=2000
In year 2015, t=4, substitute t=4 in the above equation ,we get
![p=2000-50(4)\\\Rightarrow\ p=2000-200\\\Rightarrow\ p=1800](https://tex.z-dn.net/?f=p%3D2000-50%284%29%5C%5C%5CRightarrow%5C%20p%3D2000-200%5C%5C%5CRightarrow%5C%20p%3D1800)
Hence, the projected population of the high school in 2015=1800
Now, put p=1600 in the function , we get
![1600=2000-50t\\\Rightarrow50t=2000-1600\\\Rightarrow50t=400\\\Rightarrow\ t=\frac{400}{50}\\\Rightarrow\ t=8](https://tex.z-dn.net/?f=1600%3D2000-50t%5C%5C%5CRightarrow50t%3D2000-1600%5C%5C%5CRightarrow50t%3D400%5C%5C%5CRightarrow%5C%20t%3D%5Cfrac%7B400%7D%7B50%7D%5C%5C%5CRightarrow%5C%20t%3D8)
Now, 2011+8=2019
Hence, in <u>2019</u> the population be 1600 students
