Answer:

See below

Step-by-step explanation:

The square root of a number is defined as \pm y=\sqrt[2]{x} where (\pm y)^{2} gives the original number. For example, \sqrt{4}=\pm2 because 2^{2}=2*2=4 and (-2)^{2}=-2*-2=4.

Example of Calculating Square Roots with Multiplication :

  • The square root of 9 is 3. The number 9 is an integer. This number comes from multiplying 3×3 which results in the number 9
  • The square root of 25 is 5. The number 25 is an integer. This number comes from multiplying 5×5 which results in the number 25
  • The square root of 81 is 9. The number 81 is an integer. This number comes from multiplying 9×9 which results in the number 81
  • The square root of 100 is 10. The number 100 is an integer. This number comes from multiplying 10×10 which results in the number 100

Example of Calculating Square Roots by Division

  • The square root of 4 is 2. The number that divides 4 is the number 2, like 4: 2 makes the number 2. It cannot be divided anymore and can be multiplied by itself.
  • The square root of 9 is 3. The number that divides 9 is the number 3, such as 9: 3 to produce the number 3. It cannot be divided anymore and can be multiplied by itself.
  • The square root of 25 is 5. A number that divides 25 is 5, as 25:5 makes 5. It is indivisible and can be multiplied by itself.

Solve the system of elimination -2x+2y+3z=0 -2x-y+z=-3 2x+3y+3z=5
Dahasolnce [82]

Answer:

x = 1 , y = 1 and z = 0

Step-by-step explanation:

-2x+2y+3z=0    ------(1)

-2x-y+z=-3     --------(2)

2x+3y+3z=5    ---------(3)

<u>To find the values of x,y and z</u>

(3) - (2)⇒ 2y + 4z = 2

y + 2z = 1   --------(4)

(1) - (2)⇒ 3y +2z =3   ---(5)

(5) - (4)⇒ 2y = 2

y = 1

Substituting the value of y in (4) we get z =0

Substituting the value of y and z  in (1) we get x = 1

Therefore x = 1 , y = 1 and z = 0

Solve 15 ≥ -3x or 2/5 x ≥ -2.
ipn [44]

Answer:

x ≥ -5

Step-by-step explanation:

15≥-3x

<em>switch sides</em>

<em>-3x≤15</em>

<em>Multiply both sides by -1 (reverse the inequality)</em>

<em>(-3x)(-1)≥15(-1)</em>

<em>Simplify</em>

<em>3x≥-15</em>

<em>Divide both sides by 3</em>

<em>3x/3≥ -15/3</em>

<em>Simplify</em>

<em>x≥ -5</em>
