The enrollment of a school was 1200. Since then, it has increased at a rate of 35 students per year. Write an equation to repres

Romashka [77]

The general equation to represent the enrollment of the school each year after 2000 = 1200 +35 n

where n = number of years after 2000.

Step-by-step explanation:

Here, according to the question:

The initial number of students enrolled in the school = 1200 students

The number of students increased each year = 35 students

Now if the initial year is 2000, then the number of student in the first year

= Initial enrollment + ( n x Number of students increasing each year )

where n : The total number of years after 2000

So, the number of students in first year after 2000 for n = 1 is

1200 + ( 1 x 35) = 1235

The number of students in second year after 2000 for n = 2 is

1200 + ( 2 x 35) = 1270

The number of students in third year after 2000 for n = 3 is

1200 + ( 3 x 35) = 1305

Hence, the general equation to represent the enrollment of the school each year after 2000 = 1200 +35 n where n = number of years after 2000.

Answer- y = - x/2 + 5

Step by step - Replace f (x) with y.

Y = - 2x + 10

Interchange the variables.

x= -2y + 10

Solve for y.

Multiple-Choice The average distance

murzikaleks [220]

Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).

If you do $\frac{meters}{meters/second}$ , your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
