Answer:

y ≤ -14/3 or y ≤ - 4 2/3

Step-by-step explanation:

y/4 -y - 1/2 ≥ 3

- 3/4 y - 1/2+1/2 ≥ 3 + 1/2

- 3/4 y ≥ 7/2

- 3/4 y*4/3 ≥ 7/2*4/3

- y ≥ 14/3

y ≤ -14/3 or y ≤ - 4 2/3

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

y = 2x - 4

y = -x + 5

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    2x - 4 = -x + 5
  2. Add <em>x</em> to both sides:           3x - 4 = 5
  3. Add 4 to both sides:           3x = 9
  4. Isolate <em>x</em>:                              x = 3

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = -x + 5
  2. Substitute in <em>x</em>:                       y = -3 + 5
  3. Add:                                        y = 2

What is 4/5 - 2/3?<br> Someone please answer.<br> I have to write up to 20 characters so yh.
disa [49]
Change 4/5 - 2/3 so that the denominator is th same. Let’s try 15.
So, 12/15 - 10/15.
Then, subtract to get 2/15.

Hope it helped :)
