2. Another machine is used to make 10 mm long bolts. For this machine, the bolts must have an error of less than 0.1 mm to be accepted. This can be represented by |x – 10| < 0.1.a. Write this inequality as a compound inequality without absolute value bars.b. Solve the compound inequality.c. Graph the solutions on a number line.d. What do the solutions of the inequality mean for the bolt?3. Special precision bolts are made by another machine. These are for jobs that require more exact measurements. The bolts must be within 0.01 mm of 8 mm. This is represented by |x – 8| < 0.01. a. Write this inequality as a compound inequality without absolute value bars.b. Solve the inequality.c. Graph the solutions on a number line.d. What do the solutions of the inequality mean for the bolt?4. Suppose 1.5-inch long bolts are made by another machine and have to be within 0.125 inches of 1.5 inches.a. Write an absolute value inequality to represent this tolerance.b. Rewrite the absolute value inequality as a compound inequality without absolute value bars.c. Solve the compound inequality.d. What does the solution mean for the bolts?30 points!!! need help asape. Give an example of one acceptable length for a bolt.f. Give an example of one non-acceptable length for a bolt.

Line segment AB is shown on a coordinate grid: A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment AB is shown with A as ordered pair 1, 3 and B as ordered pair 5, 3. The line segment is rotated 270 degrees counterclockwise about the origin to form A'B'. Which statement describes A'B'? A'B' is parallel to AB. A'B' is half the length of AB. A'B' and AB are equal in length. A'B' is greater than twice the length of AB.
