Y/z dosent belong on it I even think its not a number.Lol hope this helps :)
<span>Set up a proportion so 12/5= 30/x so cross multiply 5 times 30 is = to 12x now divide 150 (which is 30 times 5) by 12 and you get 12.5. So 12.5 is your answer
</span> y 12 - x 5
y 30 - x ?
x= 30 × 5 ÷ 12
<span>x = 12.5</span>
The intervals refer to the x values where the function (graph) is increasing which means the y values are getting larger from left to right. Parantheses are used not brackets (parantheses means it doesn't include the value and brackets mean it does) so here the intervals would be
( negative infinity , -3)U( -3, 0 )
