Agraph of an inequality includes an open circle and an arrow pointing left. explain how you would use that information to choose which symbol to use to write an inequality.

Since the circle is open, the symbol must be < or="">, because the boundary point is not included. The arrow points left, so the solution set includes all values less than the boundary point. I would use < in="" my="">

Whether the circle is open or closed determines whether the boundary point is included in the solution set.The direction of the arrow indicates whether the inequality involves greater than or less than.

Step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
