Answer:
u= -8/17 [-8, ∞)
Step-by-step explanation:
solve it like regular equation
17u≥-8
divide 17 on both side
then you get u≥-8/17
so, (u) is any value greater than or equal to -8/17
less than equal means solid dot on number line i think its called also mean ([) meaning it includes this value too. It is a multiplication so it can be any number above -8 or -8 itself. Thus, the interval notation will be [-8, ∞). Infinite is not a fix number so we use this (). hope this helps good luck
