Question

other than a no solution set, use interval notation to express the solution set and then graph the solution set on a number line. 2x + 4 < 10. select the correct choice below and, if necessary, fill in the answer box to complete your choice. a. the solution set is (-∞,3). (type your answer using interval notation.) b. the solution set is ∅. choose the correct graph below. a. number - line graph with arrow pointing left and ending at 3 with a closed - circle b. number - line graph with arrow pointing right and starting at 3 with a closed - circle c. number - line graph with arrow pointing left and ending at 3 with an open - circle d. the solution set is ∅.

Explanation:

Step1: Isolate the variable term

Subtract 4 from both sides of $2x + 4<10$. We get $2x+4 - 4<10 - 4$, which simplifies to $2x<6$.

Step2: Solve for x

Divide both sides of $2x<6$ by 2. So $x < 3$, which in interval - notation is $(-\infty,3)$.
The graph of the solution set $x < 3$ is a number - line with an open circle at 3 and an arrow pointing to the left.

Answer:

A. The solution set is $(-\infty,3)$
A.
