Graph the system below and write its solution. <br> 2X+Y=-6<br> Y= -1/3X-1
puteri [66]
2x + y = -6
y = ⁻¹/₃x - 1

2x + (⁻¹/₃x - 1) = -6
     2x - ¹/₃x - 1 = -6
          1²/₃x - 1 = -6
                  + 1  + 1
               1²/₃x = -5
                1²/₃    1²/₃
                    x = -3

y = ⁻¹/₃x - 1
y = ⁻¹/₃(-3) - 1
y = 1 - 1
y = 0
(x, y)= (-3, 0)

elixir [45]

Answer: 2r(0)/3.

Step-by-step explanation:

So, we are given one Important data or o or parameter in the question above and that is the function of the form which is given below(that is);

S(r) = (r0 - r) ar^2 -----------------------------(1).

We will now have to differentiate S(r) with respect to r, so, check below for the differentiation:

dS/dr = 2ar (r0 - r ) + ar^2 (-1 ) ---------;(2).

dS/dr = 2ar(r0) - 2ar^2 - ar^2.

dS/dr = - 3ar^2 + 2ar(r0) ------------------(3).

Note that dS/dr = 0.

Hence, - 3ar^2 + 2ar(r0) = 0.

Making ra the subject of the formula we have;

ra[ - 3r + 2r(0) ] = 0. -------------------------(4).

Hence, r = 0 and r = 2r(0) / 3.

If we take the second derivative of S(r) too, we will have;

d^2S/dr = -6ar + 2ar(0). -------------------(5).

+ 2ar(0) > 0 for r = 0; and r = 2r(0)/3 which is the greatest.
