Question

Choose the correct description of the graph of the inequality -2x > 10.

Open circle on -5, shading to the left.

Closed circle on -5, shading to the left.

Open circle on -5, shading to the right.

Closed circle on -5, shading to the right.

Answer 1

-2x > 10
x < -5

Answer 2

huh?

Answer 3

Which part you do not understand?

Answer 4

wait now i understand what you said but i still dont know the answer

Answer 5

x < -5
The graph is shaded left and an open circle because it never includes -5

Answer 6

It is a closed circle if the inequality was x <= -5

Answer 7

how did the sign flip ?

Answer 8

When you multiply or divide by a negative number, the sign flips

Answer 9

Quick lesson on inequalities :
Inequality solving is about the same as equation solving except for some rules. One such rule is when dividing/multiplying by a negative, it changes the inequality sign.
If there is an equal sign involved in the inequality, then there will be a closed circle. If there is no equal sign, then it is an open circle. If the inequality sign is greater, shading will be to the right. If the inequality sign is less then, the shading will go to the left. It is that simple.

Answer 10

ok so is the answer b?

Answer 11

It's A... Since it's a open circle

Answer 12

ok i get it now thanks
