Interpreting Solutions:

Darina [25.2K]

We have that
solution is
x <-10 or x>=25

for
x < -10
the solution is the interval (-∞, -10)

and
for
x>=25
the solution is the interval [25,∞)

therefore
the solution for
x <-10 or x>=25
is
(-∞, -10) ∪ [25,∞)

<span>the solution is any value of x less than -10 or greater than or equal to 25</span>
