Alg 2 CP Practice Review 1.4-1.5

Solve for x.

 $3-2x\ >\ 11\ \ or\ \ \ 3x\ +1\ >\ 16$  


(Just type both inequalities that you get with or in the middle. DO NOT USE ANY SPACES, not even for the word or!)

Solve for x.
 $-10\ <\ 2x\ -6\ <\ -4$  

(Just type the inequality that you get.  Do not use spaces.)

Solve the following absolute value equation for x.

 $-9\left|3x+3\right|+10\ =\ -17$  

(Do not write x= in your answer. Just type the answer(s) that you get. If you get more than one answer just list them in the answer box using a comma in between but NO SPACES!If your answer is no solution, type no solution)

Evaluate the following absolute value expression.

 $-4\left|a\ -12b\right|\ \ \ if\ \ \ a\ =\ -6\ \ and\ \ b\ =\ \frac{1}{4}$  

(Just type the number that you get. Do not use spaces)

Solve the following absolute value equation.

 $7\ -\ \left|4-2x\right|\ =\ 21$  


(Do not write x= in your answer. Just type the answer(s) that you get. If you get more than one answer just list them in the answer box using a comma in between but NO SPACES!If your answer is no solution, type no solution)

Solve the following absolute value equation. Check for extraneous solution(s).

 $\left|2x-6\right|\ =\ 4x$  

(Do not write x= in your answer. Just type the answer(s) that you get. If you get more than one answer just list them in the answer box using a comma in between but NO SPACES!If your answer is no solution, type no solution)

On the graph of   $-5\ \le\ x$  , there would be

• an open circle at -5, shaded to the right

• an open circle at -5, shaded to the left

• a closed circle at -5, shaded to the right

• a closed circle at -5, shaded to the left

True or False.    If    $x<3\ \ or\ \ x>\ 11$ , then  $x\ =\ 8\$  is a solution to this inequality. 

• True 

• False
