Answer:

  • \sqrt{h^2 + k^2}

Step-by-step explanation:

  • Point O has coordinates (0, 0)
  • B has coordinates (h, k)
  • C has coordinates (h, 0)

<u>Use the distance formula to find the length of OB:</u>

  • OB = \sqrt{(h-0)^2 + (k-0)^2} = \sqrt{h^2 + k^2}

Find the value of x.
Colt1911 [192]

Answer: x=4

Step-by-step explanation: write down 11x-2+9x+1=19x+3, then combine the like terms... 20x-1=19x+3, then subtract 19x from both sides which will give you x-1=3, and 4-1=3 so x=4

Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

4x - 12 ≤ 16 + 8x

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

  1. Subtract 4x on both sides:                    -12 ≤ 16 + 4x
  2. Subtract 16 on both sides:                     -28 ≤ 4x
  3. Divide 4 on both sides:                          -7 ≤ x
  4. Rewrite:                                                   x ≥ -7

Here we see that any value <em>x</em> greater than or equal to -7 would work as a solution to the inequality.

∴ our answer is -7.
