Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

3(4x - 5) - 4x + 1 = -6

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 3:                    12x - 15 - 4x + 1 = -6
  2. Combine like terms:       8x - 14 = -6
  3. Isolate <em>x</em> term:                 8x = 8
  4. Isolate <em>x</em>:                          x = 1

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    3(4(1) - 5) - 4(1) + 1 = -6
  2. Multiply:                               3(4 - 5) - 4 + 1 = -6
  3. Subtract:                              3(-1) - 4 + 1 = -6
  4. Multiply:                               -3 - 4 + 1 = -6
  5. Subtract:                              -7 + 1 = -6
  6. Add:                                     -6 = -6

Here we see that -6 does indeed equal -6.

∴ x = 1 is the solution to the equation.

Can someone explain thoroughly how I am meant to solve this?
BartSMP [9]

Answer:

I got x<equal to -11 or x>equal to4

Step-by-step explanation:

x^2+15x+44=0

(x+4)(x+11)=0(Factor left side of equation)

x+4=0 or x+11=0(Set factors equal to 0)

x=−4 or x=−11

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x<−11(Works in original inequality)

−11<x<−4(Doesn't work in original inequality)

x>−4(Works in original inequality)

Answer:

x<−11 or x>−4

Find by means of a vector( quantity) diagram . The resultant of two forces of 7 newton and 3 newton acting at right angle to one
8090 [49]

Answer:

The resultant of two forces of 7N and 3N acting at a right angle to one another is √58 N.

Step-by-step explanation:

Let the magnitude of the force of 7N be denoted as “F₁” on the x-axis and the magnitude of the force of 3N be denoted as “F₂” on the y-axis.

We are given that the two forces make an angle of 90° to one another as shown in the figure attached below.

Also, in the figure, we can see that the resultant force is denoted as “F”.

Now,  

The magnitude of the resultant force can be calculated by using the Pythagoras theorem,  

 

∴ F = √[F₁² + F₂²]

⇒ F = √[7² + 3²]

⇒ F = √[49 + 9]

⇒ F = √[58] N

What is the measure of x?
expeople1 [14]

Answer:

Step-by-step explanation:

Use similar triangles and proportions to solve:

\frac{4}{6}=\frac{10}{6+x} and cross multiply:

4(6 + x) = 60 and

24 + 4x = 60 and

4x = 36 so

x = 9
