Solve the following one step inequality for the unknown variable

1. x/2>9

2. x/-2> 9

3. x-7 > 14

4. x-7 > -14

5. 5x< 10

6. -5x < 10

7. X-3 < 9

8. x-3 < -9

Answers

Answer 1

Answer:

1. x>18    2.x<-18     3. x>21     4. x>-7     5. x<2     6. x>-2     7. x<12    8.x<-6

Step-by-step explanation:

1. x/2>9 Pretend the inequality is an equal sign...

x/2=9 *2            x=18

If x>18; 20>18

20/2 = 10

10>9 so it works

If x<18      10<18

10/2 = 5

5<9 so it dosent

2. x/-2>9

x/-2=9

x=-18

If x>-18

0>-18

0/-2=0

0<9 so it doesent work.

x<-18; x=-20

-20/-2=10

10>9 So it works

3. x-7>14 --> x-7=14 ---> x=21

If x>21; x=22 --> 22-7=15; 15>14 (it works)

If x<21; x=20 --> 20-7=13; 13<14 (so it does not work)

4. x-7>-14 --> x-7=-14 --> x=-7

If x>-7; x=0 ---> 0-7=-7 --> -7>14 (so it works)

If x<-7; x=-10 ---> -10-7=-17 --> -17<14 (so it does not work)

5. 5x<10 --> 5x=10 --> x=2

If x>2 x=3 --> 5*3=15 15>10 (does not)

If x<2 x=1 --> 5*1=5 5<10 (works)

6. -5x<10 -5x=10  x=-2

If x<-2 x=-3 -3*5=-15 -15<10 (no)

If x>-2 x=0 5*0=0 0<10 (works)

7. x-3<9  x-3=9 x=12

if x>12 x=13 13-3=10 10>9

If x<12 x=10 10-3=7 7<9 (works)

8. x-3<-9 x-3=-9   x=-6

if x>-6; x=13; 13-3=10 10>-9

if x<-6 x=-10 -10-3=-13   -13<-9 (works)

Step-by-step explanation:

If a parallelogram has at least one right angle, this means that the opposite angles also measures 90 degrees because opposite angles are congruent in a parallelogram. Also, The other angles will then add up to 180 degrees but due to them being equal, they also will measure 90 degrees.

Hence, A parallelogram with at least one right angle is a rectangle.

Answer:

option B

Step-by-step explanation:

A parallelogram ABCD

To find : Which graph shows a method for finding the image of point D if the parallelogram is reflected across the dashed line?

Since forming the reflected image follows Every point on the image will be the same distance as its corresponding point from the pre-image.  

This distance will be perpendicular to the line of reflection i.e. dashed line  

And the second option shows the correct image .

In the second image the perpendicular was draw along the axis of reflection .

Hence the option B is correct .

Answer:

The interquartile range (IQR) of the data set is:

                                3.5

Step-by-step explanation:

The data points are given as follows:

       0, 1 1/2, 2 1/2, 3, 4, 4, 4, 7, 7 1/2

i.e.   0 , 1.5 , 2.5 , 3 , 4 , 4 , 4  , 7 , 7.5

There are a total of 9 data points and we know that the median of the data is the central tendency of the data and it always exist in the middle of the data.

Here we have 9 data points.

and hence the median exist at the the 5th place.

Hence, Median of data of Middle quartile i.e. = 4

Also, the  lower set of data is:

                 0 , 1.5 , 2.5 , 3

and the first quartile or the lower quartile i.e.  is the median of the lower set of data.

i.e.  

The upper set of data is:

                 4 , 4  , 7 , 7.5

and the third quartile or the upper quartile i.e.  is the median of the upper set of data.
