Best ResponseYou've already chosen the best response.01. it would be 2x/5 because the 9's cancel each other out. ================================= 2. 2  x + 2   1 = 5  add 1 to both sides 2  x + 2  = 6  divide both sides by 2  x + 2  = 3.....we basically wanted to get the absolute value and everything in it by itself and everything else on the other side of the equal sign. Now we can set up 2 equations. x + 2 = 3 (x + 2) = 3 x = 3  2 x  2 = 3 x = 1 x = 5 x = 5 so...x = 1 and x = 5 ================================= 3.  4b  8  +  1  b^2  + 2b^3.....when b = 2 first we sub in our 2 for b  4(2)  8  +  1  (2^2)  + 2(2^3) =  8  8  +  1  (2^2)  + 2(2^3) = 0 +  1  4  + 2(8) = 0 +  5   16 =.....absolute values are positive even when they say negative 0 + 5  16 =  11 You might need a second opinion on this one ================================= 4. ??...sorry ================================= 5. f(x) =  2x  1  + 10.....when x = 5 sub in 5 for x f(5) =  2(5)  1  + 10 f(5) =  10  1 + 10 f(5) =  11  + 10....absolute values are positive f(5) = 11 + 10 f(5) = 21 ================================== 6. 5x  12y = 11 .... add 5x to both sides 12y = 5x + 11  divide both sides by 12 y = (5/12)x  11/12  slope intercept form Now, in y = mx + b form, the slope is in the m position and the y intercept is in the b position. So your slope is 5/12 and your y int is 11/12
