We can use the distance formula to find the distance between these points.

Distance formula: \sqrt{(x.2 - x.1)^{2} + (y.2 - y.1)^{2}}

√(-5 - 6)² + (-3 - (-3))²

√121 = 11

The difference between the points is 11.

sweet [91]

Answer:

(-1, 1)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

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

3 + 2x - y = 0

-3 - 7y = 10x

<u>Step 2: Rewrite systems</u>

3 + 2x - y = 0

  1. Add <em>y</em> to both sides:                    3 + 2x = y

<u>Step 3: Redefine systems</u>

y = 2x + 3

-3 - 7y = 10x

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                     -3 - 7(2x + 3) = 10x
  2. Distribute -7:                        -3 - 14x - 21 = 10x
  3. Combine like terms:            -14x - 24 = 10x
  4. Add 14x on both sides:        -24 = 24x
  5. Divide 24 on both sides:     -1 = x
  6. Rewrite:                                 x = -1

<u>Step 5: Solve for </u><em><u>y</u></em>

  1. Define original equation:                    -3 - 7y = 10x
  2. Substitute in <em>x</em>:                                     -3 - 7y = 10(-1)
  3. Multiply:                                                -3 - 7y = -10
  4. Add 3 to both sides:                            -7y = -7
  5. Divide -7 on both sides:                      y = 1

<u>Step 6: Graph</u>

<em>Check the solution set.</em>

Answer:

x = (h-12y-2)/4

Step-by-step explanation:

Here, we want to make x the subject of the formula

We have this as:

h = 4x + 12y + 2

4x = h-12y-2

x = (h-12y-2)/4

An airplane flies 810 km in 1.5 hours. How far will the plane fly into. Two hours if it maintains the same airspeed
nadezda [96]

It would help to first find the unit rate. We know that the plane flies 810 km per 1.5 hours. Divide by 1.5 on both sides:

810/1.5 = 540 km/hour

Then, multiply both the hour and the distance by 2:

540 * 2 = 1080 km/2 hours.

You have inherited a large collection of audio compact discs and decide to purchase a HiFi system to play them. At the retailer
leva [86]

Answer:

24

Step-by-step explanation:

Since at the retailer you find a choice of 4 CD players, 2 amplifiers and 3 sets of speakers. We have 4 different ways of selecting the CD players, we also have 2 different ways of selecting the amplifiers and 3 different ways of selecting the 3 sets of speakers.

So, the total number of different HiFi systems are available to purchase from this retailer is 4 × 3 × 2 = 24 .

So we have 24 different HiFi systems are available to purchase from this retailer
