How do you graph the inequality of 4x-2y≤6 ?
Orlov [11]

4x - 2y ≤ 6      <em>subtract 4x from both sides</em>

-2y ≤ -4x + 6     <em>change the signs</em>

2y ≥ 4x - 6     <em>divide both sides by 2</em>

<h3>y ≥ 2x - 3</h3>

y = 2x - 3 - it's a linear function. We need only two points to plot the graph.

Choose any two values of x and calculate the values of y:

for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)

for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

Please help me with this geo problem
Over [174]

Answer:

  • x = 1.25
  • y = 1.75

Step-by-step explanation:

Find x

  • 8/10 = 5/(5 + x)          Cross multiply
  • 8*(5 + x) = 10*5          Combine on the right
  • 8(5 + x) = 50              Remove the brackets on the left.
  • 40 + 8x = 50              Subtract 40 from both sides.
  • 40-40 +8x = 50-40    Combine
  • 8x = 10                        Divide by 8
  • 8x/8 = 10/8                 Divide
  • x = 1.25

Find y

  • 7/(7 + y) = 8/10                    Cross multiply
  • 8*(7 + y) = 10 * 7                  Combine the right
  • 8(7 + y) = 70                        Remove the brackets.
  • 56 + 8y = 70                       Subtract 56 from both sides
  • 56 - 56 + 8y = 70 - 56       Combine
  • 8y = 14                                Divide by 8
  • y = 1.75
