This is 4x=2x-2 as a graph
Let x is the odd integer
x +2 is the next odd integer
so sum of an odd integer and the next odd integer:
x + (x+2)
The answer to the question
Answer:
Step-by-step explanation:
I'm not exatcly sure what is meant by magnitude but if it is the slope it is simply -7 if it is asking about the actual magnitude or length of the vector then we use pthagorean theorum which is:

when adjusted to solve for the answer is

which is c = sqrt (1^2) + (-7)^2 =
would be the exact answer
They would need 22 teachers to have 15 students per teacher because 22*15=330
