Someone help me please:)

   (12, 4)

Step-by-step explanation:

The point (12, 4) is the only one in the doubly-shaded area of the graph. Of the choices offered, it is the only one that is a solution.

I prefer to use a graphing calculator to draw the graph and plot the points. That is more interesting to me than evaluating the inequalities over and over.

Here, we find the first inequality is only satisfied by the first point. We can rewrite it so we're not messing with fractions.

  y ≥ -5/6x +2

  6y ≥ -5x +12 . . . . multiply by 6

  5x +6y ≥ 12 . . . . . add 5x

Now, to check the points:

  (12, 4) -- 5(12) +6(4) ≥ 12 . . . true

  (0, -2) -- 5(0) +6(-2) ≥ 12 . . . not true

  (6, -7) -- 5(6) +6(-7) ≥ 12 . . . not true

  (-12, 7) -- 5(-12) +6(7) ≥ 12 . . . not true

Just to make sure, we can use the first point in the second inequality:

  (12, 4) -- 4 ≤ 5(12) -1 . . . true

The point (12, 4) would be a solution to the two inequalities.

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
