Which of the following has no solution ?

ANSWER

{x|x<0} and {x|x>0}

EXPLANATION

If the two inequalities have an intersection,then it has a solution.

If the two inequalities have no intersection, then there is no solution.

The inequality {x|x<0} and {x|x>0} has no intersection, there is no solution.

The inequalities

{x|x≤0} and {x|x≥0},

{x|x≤0} or {x|x≥0}

both have intersection, therefore have solutions.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
