List the integers that satisfy both of these inequalities 2x+9<0 x>-12 put the answers on one line

lbvjy [14]

Answer:

Step-by-step explanation:

Given the inequality expressions

2x+9<0 and x>-12

2x+9<0

2x< 0-9

2x < -9

x < -9/2

x < -4.5

Since x >-12

-12 < x

Combining both inequalities

-12 <x < 4.5

<em>The integers between the intervals are -11, -10, -9, -8, -7, -6 and -5 </em>

Which expressions are in simplest fom? Check all that apply.

Llana [10]

Answer:

(1/x4), (w7/x2), (a-9), (1?b5)

Step-by-step explanation:

x3+y3 can be simplified by factoring out a 3.

=3(x+y)

1/a2+b2 can be simplified by finding a common denominator

=1/a2+a2b2/a2

=1+a2b2/a2

Hope this helped!

Quadrilateral RPQS is a rectangle. Label the missing measures.

Taya2010 [7]

Answer:

Part 1) $PR=9\ units$

Part 2) $PQ=12\ units$

Part 3) $PS=15\ units$

part 4) $QR=15\ units$

Part 5) $RT=7.5\ units$

Step-by-step explanation:

we know that

In a rectangle opposite sides are parallel and congruent

The measure of each interior angle is 90 degrees

The diagonals are congruent and bisect each other

step 1

Find the length of side PR

we know that

$PR=QS$ ----> by opposite sides

we have

$QS=9\ units$

therefore

$PR=9\ units$

step 2

Find the length of side PQ

we know that

$PQ=RS$ ----> by opposite sides

we have

$RS=12\ units$

therefore

$PQ=12\ units$

step 3

Find the length of diagonal PS

we know that

$PS=2PT$ ---> the diagonals bisect each other

we have

$PT=7.5\ units$ ---> given problem

therefore

$PS=2(7.5)=15\ units$

step 4

Find the length of diagonal QR

we know that

$QR=PS$ ---> the diagonals are congruent

we have

$PS=15\ units$

therefore

$QR=15\ units$

step 5

Find the length of RT

we know that

$QR=2RT$ ---> the diagonals bisect each other

we have

$QR=15\ units$

substitute

$15=2RT\\RT=7.5\ units$
