Question

If x is equal 1 what number is y

Answer 1

Hello there!

Our equation is this:
y =
`(5)/( x^(2) + 1)` - 1

If x = 1, we can plug it in and then try to solve for y.
Let's plug in 1 for x.

y =
`(5)/( 1^(2) + 1)` - 1
y =
`(5)/(1 + 1)` - 1
y =
`(5)/(2)` - 1
y = 2.5 - 1

y = 1.5

I hope this helps!

Answer 2

y = 5 / x² + 1 -1 x= 1

y = 5/ (1)² + 1 -1

y = 5/ 1 + 1 -1

y = 5/2 -1

y = 2.5 -1

y = 1.5
