y=(1/2)x-1

You have to set both to y and then add. After that you solve for y

So, just add

2x+y=4
3x-y=6 +
5x+0y=10

5x=10
divide 5
x=2

sub back
2x+y=4
2(2)+y=4
4+y=4
y=0

x=2
y=0
(2,0)

the result of adding the equation is 5x=10

To determine whether the inverse of a function is a function you can perform the horizontal line test.

iris [78.8K]

Answer:

$\boxed{\text{TRUE}}$

Step-by-step explanation:

If a horizontal line intersects the graph of a function in all places at exactly one point (the horizontal line test), the inverse of the function is also a function.

For example, the inverse of a hyperbola (like ƒ(x) =1/x) is a function, because every horizontal line intersects with the graph at exactly one point.

However, the inverse of a parabola (like ƒ(x) = x²) is not a function, because a horizontal line intersects with the graph at two points.
