You work as a lab assistant. Each morning you are responsible for grouping the correct number of test tubes for each experiment that will be conducted that day. Today 40 test tubes will be used for 12 experiments. The first two experiments will require 4 test tubes each. Six of the experiments will require 3 test tubes each, and 2 of the experiments will require 2 test tubes each. Each of the two remaining experiments will use exactly the same number of test tubes.

Which calculation is appropriate to perform first when determining the number of test tubes that will be used for each of the two remaining experiments?

A)

10

2

B)

40 − 30

C)

40 − 12

D)

2(4) + 6(3) + 2(2)

D

Step-by-step explanation:

40 - [(2)(4) + (6)(3) + (2)(2)]

40 - 30

10 for the remaining two

Each of the 2:

10/2 = 5

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
