Using the properties of inequalities, write down the inequality that you will get if you: add the number –5; 2.7; 7; to both sid
puteri [66]

Answer:

See below

Step-by-step explanation:

1..........................

  • 18 >−7

Add –5; 2.7; 7 to both sides

  • 18 -5 > -7 - 5 ⇒ 13 > -12
  • 18 + 2.7 > - 7 + 2.7 ⇒ 20.7 > - 43
  • 18 + 7 > -7 + 7 ⇒ 25 > 0

2..........................

  • 5 > -3

Subtract 2; 12; -5 from both sides

  • 5 - 2 > -3 -2 ⇒ 3 > - 5
  • 5 - 12 > -3 - 12 ⇒ -7 > -15
  • 5 -(-5) > -3 - (-5) ⇒ 10 > 2

3..........................

  • - 9 < -6

Multiply both sides by 3; −3; −1

<em>When multiplying both sides of inequality by positive number the sign stays as is, when multiplying both sides of inequality by negative number the sign reverses</em>

  • -9 *3 < -6*3 ⇒ -27 < - 18
  • -9*(-3) > -6*(-3) ⇒ 27 > 18
  • -9*(-1) > -6*(-1) ⇒ 9 > 6

The following values of (x) and f(y) are given. Find the best value of (dy/dx) at
velikii [3]

Answer:

dy/dx at x=6 is 0.334

Step-by-step explanation:

The center difference method requires that the values of the function are given in equal intervals which is the case, and allows one to find the value for x = 6 using those of the function for x = 5.5 and for x = 6.5 as follows:

\frac{dy}{dx} =\frac{3.7436-3.4096}{6.5-5.5} =0.334

Find f(2) for the following functions: f(x) = x - 14
BaLLatris [955]

Answer:

<h2>f(2) = - 12</h2>

Step-by-step explanation:

f(x) = x - 14

To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2

We have

f(2) = 2 - 14

We have the final answer as

<h3>f(2) = - 12</h3>

Hope this helps you
