How do I solve this equation?
frosja888 [35]

Answer:

x=-3/11

Step-by-step explanation:

(x+3)/5 +2x=0

Multiply both sides by 5 to get rid of the fraction

5*( x+3)/5 +5*2x=0*5

x+3 + 10x =0

Combine like terms

11x +3 = 0

Subtract 3 from both sides

11x+3-3 =0-3

11x = -3

Divide by 11

11x/11 = -3/11

x = -3/11

dalvyx [7]

Matching each equation of the plecewise function represented in the graph will be:

  • 2 < x < 3 = 3 - x
  • 0 < x < 2 = 1
  • x = 2 = x
  • 3 < x < 5 = 5 - x

<h3>How to illustrate the information?</h3>

It should be noted that a domain simply means the set of inputs that are accepted by the function.

In this case, the equation of the piecewise function represented is given.

The graph is attached.
