3x+3y=-3 solve using the elimination

Mathematics
1 answer:
timofeeve [1]3 years ago
5 0

Simplifying

3x + 3y = -3

Solving

3x + 3y = -3

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

3x + 3y + -3y = -3 + -3y

Combine like terms: 3y + -3y = 0

3x + 0 = -3 + -3y

3x = -3 + -3y

Divide each side by '3'.

x = -1 + -1y

Simplifying

x = -1 + -1y

Andreas93 [3]

Answer:

  • Minimum 100 bicycles
  • Minimum cost is 13500

Step-by-step explanation:

<u>Given function:</u>

  • C(x) = 3x^2- 600x + 43500

a.

Minimum cost is obtained at vertex.

Vertex is determined by formula x = -b/2a, in standard form of

f(x) = ax^2 + bx + c

<u>Vertex of the given function is:</u>

  • x = -(-600)/(2*3) = 100

b.

<u>Cost at vertex is:</u>

  • C(100) = 3*100^2 - 600*100 + 43500 = 13500
