(multiple choice) 2. solve for x. |x| = 6 a) x = 6 b) x = -6 c) x = 6 or x = -6 d) no solution 3. given the equation, -5|x + 1| = -10, the isolated absolute value equation would be |x + 1| = -15. a)true b) false 4. given the equation, 2|x + 4| = 8, the isolated absolute value equation would be |x + 4| = 4. a)true b)false 6. solve for x. |x| = -5 a) x = 4 and x = 0 b) x = -15 and x = 9 c) x = -4 and x = -2 d) x = -3 and x = 1 e) no solutions 7. solve for x. |2x + 6| - 4 = 20 a) x = 4 and x = 0 b) x = -15 and x = 9 c) x = -4 and x = -2 d) x = -3 and x = 1 e) no solutions

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.

step-by-step explanation:

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
