5 0

Answer:

-2<x<9

Step-by-step explanation:

−21<−3x+6<12-21<-3x+6<12

Move all terms not containing xx from the center section of the inequality.

Tap for more steps...

−27<−3x<6-27<-3x<6

Divide each term in the inequality by −3-3.

−27−3>−3x−3>6−3-27-3>-3x-3>6-3

Divide −27-27 by −3-3.

9>−3x−3>6−39>-3x-3>6-3

Cancel the common factor of −3-3.

Tap for more steps...

9>x>6−39>x>6-3

Divide 66 by −3-3.

9>x>−29>x>-2

Rewrite the interval so that the left value is less than the right value. This is the correct way to write an interval solution.

−2<x<9-2<x<9

The result can be shown in multiple forms.

Inequality Form:

−2<x<9-2<x<9

Interval Notation:

(−2,9)

Zina [86]

Answer:

Step-by-step explanation:

you want maximum height reached?

\frac{dy}{dt} =46-32t\\\\at max. height velocity=0\\ 0=46-32t\\32 t=46\\t=46/32=23/16\\y=t(46-16t)\\ at t=\frac{23}{16} \\ y=\frac{23}{16}(46-16*\frac{23}{16} )\\\\y=\frac{529}{16} ft
