x² + y² – 10x + 6y + 18 = 0 x² – 10x + y² + 6y + 18 = 0 x² – 10x + 25 - 25 + y² + 6y + 9 - 9 + 18 = 0 (x-5)² + (y+3)² -16 = 0 (x-5)² + (y+3)² = 16 (x-5)² + (y+3)² = 4² Center at (5,-3) radius = 4 Part 2 1. Complete the square for x and y 2. Put in the format for a circle. (x-h)² + (y-k)² = r², center at (h,k) with radius = r

camelback mountain has an elevation change of 1,264 feet. how many pennies would it take to make a stack that high ? show all wo
gtnhenbr [62]

              Camel back Mountain = 15,168 inches (1,264 feet)

  • 1 Penny = 0.061 (.0610) Inches
  • 10 Penny = 0.61 (.610) Inches
  • 100 Penny = 6.1 (6.10) Inches
  • 1,000 Penny = 61 (61.0) Inches
  • 10,000 Penny = 610 (610.0) Inches

                                                   <u>-SOLVING-</u>

10,000 Penny = 610 inches PLUS

1,000 Penny = 61 inches AND 61 inches x 5 = 305 (5,000 Penny)

100 Penny = 6.1 inches PLUS

10 Penny = 0.61 inches AND 0.61 inches x 6 = 3.66 (60 Penny)

1 Penny = 0.061 inches AND 0.061 inches x 8 = 0.488 (8 Penny)

                                            -<u>FINAL ANSWER-</u>

610 + 305 + 6.1 + 3.66 + 0.488 = 925.248 Penny it would take.

The length of the line segment <br><br> AB equals 3x+1<br><br> BC equals 4x-5<br><br> AC equals 8x-9
yanalaym [24]

Answer:

X = 5

Step-by-step explanation:

Here is what I am picturing (not to scale)

A ----------------B-----------C

We are given the information of AB (which equals 3x + 1), BC (which equals 4x - 5), and AC (which equals 8x - 9).

With reference to the line, AB + BC = AC

So,

3x + 1 + 4x - 5 = 8x - 9

7x - 4 = 8x - 9

5 = x

I need help on this one
bulgar [2K]

Answer:

16 months

Step-by-step explanation:

Look at the chart on the left and look at what number of months is closest to 15,000. 16 is at 15,034

To solve mathematically:

y is the balance that his account would have. You want to find the amount of months it will take before it becomes $15,000, so 15000 is your y value

15,000= - 440.91x+22,060.7

-7,060.7= - 440.91x    Subtract 22,060.7 from both sides

16.0139=x   Divide both sides by - 440.91
