Five students came for after-school tutoring. lin’s teacher assigned each of them the same number of problems to complete. then he assigned each student 2 more problems. 30 problems were assigned in all. use x as the variable.

The number of problems assigned initially to each student by Lin’s teacher is 4

According to the problem

Five students came for after-school tutoring.

Lin’s teacher assigned each of them the same number of problems to complete.

Then he assigned each student 2 more problems.

30 problems were assigned in all.

we have to  use x as the variable.

Total number of problems assigned by Lin's teacher  to students = 30

Let the  total number of problems assigned  to each student initially  be x

So, the number of problems assigned   to  all the  students  initially = 5x

Also it is given that  Lin's teacher assigns 2 more problems to each student

which means he gives 10 more problems to solve

So the total number of problems given to the students can be written in the form of equation (1)  

 So, The number of problems assigned initially to each student by Lin’s teacher is 4.

Step-by-step explanation:

x = total problems

x / 5 + 5(2) = 30

x / 5 + 10 = 30

x / 5 = 20

x = 20 * 5

x = 100 <

the answer is 175.4379

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
