Solve this system of equations by graphing. First graph the equations, and then type the solution.
1 answer:
Answer:
(x, y) = (1, 4) is the solution to the graph.
Step-by-step explanation:
Given the system of the equations
The solution graph is attached below.
From the attached solution graph,
- The red line is representing the equation y=3x+1
- The blue line is representing the equation y=5x–1
From the graph, it is clear that both lines intersect at x=1 and y=4. So, the point where two lines intersect or meet is called the solution to the graph.
Thus, the point of intersection is (x, y) = (1, 4)
Therefore, (x, y) = (1, 4) is the solution to the graph.

, with discontinuity at negative
, negative
Step-by-step explanation:
we have
Simplify
Step 1
Convert to a factored form the numerator
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
so
Step 2
Simplify the function f(x)
The domain of the function f(x) is all real numbers except the number
Because the denominator can not be zero
------> with a discontinuity at
The discontinuity is at point
