Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of 'x>3 or x<-3' which can be confusing.
We simplify through bxc^2;
We obtain bc^2;
All we have to do here is to express numbers 40 and 5 in each of equations. Note that first number in brackets is always x coordinate and second number is y coordinate
First equation:
5 = 40*8 false
Second
5 = 5*40 false again
Third:
5 = 40/8 = 5 True
checking for just in case last one:
5 = 40/5 = 8 False
Correct one is C)
