Answer:
Fourth option: 30 days
Step-by-step explanation:
We three path to complete the project:
Path A:
A1 → A2 → A3
10 days → 8 days → 9 days = 27 days
Path B:
B1 → B2 → B3
2 days → 7 days → 3 days = 12 days
Path C:
C1 → C2 → C3
10 days → 8 days → 12 days = 30 days
Then the duration of the critical path is 30 days, we can't conclude the project until each path has finished
Linear functions have no exponents higher than 1, and a graph that looks like a straight line. non-linear functions have at least one exponent higher than 1, and a graph that isn't a straight line
F(x) = 1 - x
f(-3) = 1 - (-3)
f(-3) = 4
By definition, we have
So, we have to solve two different equations, depending of the possible range for the variable. We have to remember about these ranges when we decide to accept or discard the solutions:
Suppose that 
In this case, the absolute value doesn't do anything: the equation is
We are supposing 
, so we can accept this solution.
Now, suppose that 
. Now the sign of the expression is flipped by the absolute value, and the equation becomes
Again, the solution is coherent with the assumption, so we can accept this value as well.
Answer:
y=3/4x-4
Step-by-step explanation:
The form is y=mx+b so isolate y
-4y=16-3x
y=-16/4-3x/-4
y=3/4x-4
