closed circle on 4 and all numbers to the left shaded
while the left shaded part is true. If we have a > or < sign, it should be an open circle
should we have a \[\leq \] or \[\geq \] we have a closed circle. I don't see those signs for x<4
and if they give that like this Choose the true statement about the graph of 3x ≥ 6. closed circle on 2 and all numbers to the right shaded closed circle on 2 and all numbers to the left shaded open circle on 2 and all numbers to the right shaded open circle on 2 and all numbers to the left shaded
for that question, solve the inequality first. then since you have a \[\geq \] we have a closed circle
and graph according to the point of the symbol
for example if I want to graph x < 2 on a number line |dw:1437999382990:dw|
so it will be the second one
no.... not exactly... because our inequality symbol would have been \[\leq \] so that shading is going to the left.
\[3x ≥ 6. \] ok first solve this inequality by dividing 3 on both sides.
then we can obtain x by itself and since we have \[\geq \] we should be shading to the right with a closed circle
I'll give a similar example suppose we are given \[4x \geq 16 \] solving for x by dividing both sides by 4, we get \[x \geq 4 \] since we have a \[\geq \] sign we have a closed circle and based on the opposite direction of the symbol's mouth, we are shading to the right. |dw:1437999750344:dw|
