You are a school photographer taking individual and class pictures for 2 classes of 21 students each. on average, each individual picture takes 3 minutes and a class picture takes 10 minutes. about how long should it take you to get all of the pictures?

146 minutes

Step-by-step explanation:

2 class has 21 students each

2 class has students = 21+21=42

It takes time to click picture of 1 student = 3 minutes

It takes time to click picture of 42 student = minutes

                                                                      = minutes

It takes time to click picture of 1 class = 10 minutes

It takes time to click picture of 2 class = 20 minutes

So, total time = 126 minutes + 20 minutes = 146 minutes

Thus it will take 146 minutes to get all of the pictures

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
