What integer values satisfy both inequalities? − 2 < x < 3 − 2 ≤ x < 2

Answers

Given:

The inequalities are:

[tex]-2<x<3[/tex]

[tex]-2\leq x<2[/tex]

To find:

The integer values that satisfy both inequalities.

Solution:

We have,

[tex]-2<x<3[/tex]

[tex]-2\leq x<2[/tex]

For [tex]-2<x<3[/tex], the possible integer values are

[tex]x=-1,0,1,2[/tex] ...(i)

For [tex]-2\leq x<2[/tex], the possible integer values are

[tex]x=-2,-1,0,1[/tex] ...(ii)

The common values of x in (i) and (ii) are

[tex]x=-1,0,1[/tex]

Therefore, the integer values -1, 0 and 1 satisfy both inequalities.

4. THE LOV TEMPERATURES FOR A VEEK IN EDMONTON, ALBERTA ARE -15°C, -1200
-10°C, -12°C, -18°C, -20°C, AND_-25°C. WHAT IS THE MEAN LOV
TEMPERATURE FOR THE WEEK? SHOW YOUR WORK

Answers

Answer:

-16°C

Step-by-step explanation:

The lov temperatures for a week are :

-15°C, -12 , -10°C, -12°C, -18°C, -20°C, and -25°C.

We need to find the mean love temperature for the week.

Total no. of observations = 7

Mean = sum of observations/total no of observations

[tex]M=-\dfrac{15+12+10+12+18+20+25}{7}\\\\M=-16^{\circ} C[/tex]

So, the mean temperature is -16°C.

What is parallelogram?

A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.

Given:

ABCD is a parallelogram.

And BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6.

The two diagonals bisect each other.

AC = AE + EC

AC = 2AE

AC = 8x-12

The diagonals of a parallelogram are equal.

So,

BD = AC

5x+3 = 8x-12

x = 3

So, AC = 12

Therefore, the AC is 12 unit.
