On a school field trip, the school requires that there are 6 teachers for every 90 students. if 135 students attend the trip how many teachers are needed? write and solve a proportion showing your work. (3 points)

the answer is 9 teachers

Step-by-step explanation:

step one is 135-90=?

step two is if  1 teachers for 15 students

2 techers are for 30 students until you get to 135

9 teachers.

Step-by-step explanation:

We can visualize the information given as follows:

Students        teachers

   90         ⇒        6

   135        ⇒        x

Which tells us that for 90 students 6 teachers are needed, and for 135 students we have the unknown quantity of teachers x.

To find x we multiply the two cross quantities, and divide by the remaining amount

x = (135)(6) ÷ 90

x = 810 ÷ 90

x = 9

9 teachers are needed for 135 students.

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 )
