Question

can someone hell me please

Choose the correct description of the graph of the compound inequality

3x + 1 > 10 and 4x less than or greater to 20.

A number line with an open circle on 3, a closed circle on 5, and shading in between.

A number line with an open circle on 3, shading to the left, and a closed circle on 5, shading to the right.

A number line with a closed circle on 3, shading to the left, and an open circle on 5, and shading to the right.

A number line with a closed circle on 3, an open circle on 5, and shading in between

Answer 1

3x + 1 > 10 4x <= 20
3x > 10 - 1 x <= 20/4
3x > 9 x <= 5
x > 3

Learn this...
if there is an equal sign, it is a closed circle
if there is no equal sign, it is an open circle
if < less then, shading to the left
if > greater then, shading to the right

answer is A : open circle on 3,(because there is no equal sign), closed circle on 5,(because there is an equal sign), shading in between.(because x is greater then 3, shading goes to the right, and because x is less then 5, shading goes to the left.

Answer 2

thank you so much (: I appreciate it
