Answer:
x = -1/3
Step-by-step explanation:
Move 5 to the other side of the equation
3x = 4-5
3x = -1
x = -1/3
ANSWER
x coordinates of the intersection points
EXPLANATION
The given system of equations is:


We want to use the graph of these functions to solve

The point of the intersection of the graph gives the solution to the simultaneous equation above.
Hence the x-coordinates of the intersection points gives the solution set of

The last choice is correct.
Step-by-step explanation:
number2 the answer is a and
number 3 the answer is letter b
The domain of the function is \[A \ge0\] If A is negative we get an imaginary number for the radius. This makes sense because the area of a circle cannot be negative.
