Best ResponseYou've already chosen the best response.2you're on the right track, but when we have absolute value signs, we must consider the positive and negative solutions to the equation so, going by what you have so far, we have:  7  3/2x  = 8, where   are the absolute value signs, with me so far?

Best ResponseYou've already chosen the best response.2So, going from there, we need to write two different equations 7  3/2x = 8 and 7  3/2x = 8

Vocaloid

Best ResponseYou've already chosen the best response.2then we solve each one separately so, let's tackle the first one 7  3/2x = 8 first, subtract 7 from both sides and tell me what you get

Vocaloid

Best ResponseYou've already chosen the best response.2yup, now we divide both sides by (3/2)

Vocaloid

Best ResponseYou've already chosen the best response.2yup, so x = 2/3 now, we're only halfway done, there's another value of x that works for the equation. now we solve 7  (3/2)x = 8 using the same process as before. start by subtracting 7 from both sides

Vocaloid

Best ResponseYou've already chosen the best response.2yup, so x = 10 and x = 2/3 are your two solutions, good work ready for the next one?

Best ResponseYou've already chosen the best response.0Solve. [x+8] +9=7 same as the one before

Vocaloid

Best ResponseYou've already chosen the best response.2ah, not quite, there's an important rule to remember when it comes to absolute values. the absolute value of a mathematical expression cannot be negative as an example, if we have x = a, then a must be a positive number in order to have a solution so, looking at our problem, we first subtract 9 from each side to get x + 8 = 2 the absolute value of any quantity must be positive, so this has no solution

Best ResponseYou've already chosen the best response.2does that make sense? are you ready to move to the next one?

Best ResponseYou've already chosen the best response.0Yes it does. I thought it was but wanted to make sure.. Solve using appropriate substitution. (x^2 6x)^2 11(x^2 6x) 30=0

Best ResponseYou've already chosen the best response.0I got 3+ square root 14 and 3+ square root 15 But its wrong...

Best ResponseYou've already chosen the best response.2huh, this is a tricky one, hold on a moment

Vocaloid

Best ResponseYou've already chosen the best response.2well, I'm not sure if this is the right approach but...I'm guessing it wants us to substitute a variable for x^2 6x so, if we let a = x^2 6x, then our equation becomes a^2  11a  30 after we apply the quadratic formula we get dw:1440800955390:dw

Best ResponseYou've already chosen the best response.0I factored (w5)(w6)

Vocaloid
 one year ago
Best ResponseYou've already chosen the best response.2I'm not really sure if my thinking is correct and that factoring doesn't work, that would only work for positive 30, not 30 (w5)(w6) = w^2  11w + 30

Best ResponseYou've already chosen the best response.2ah, I wish I could be of more help on this one :( I feel like I'm missing an obvious trick here @welshfella @SithsAndGiggles

Best ResponseYou've already chosen the best response.0Given that \(a^2  11a  30=0\) yields roots \(a=\dfrac{11\pm\sqrt{241}}{2}\), you can find the roots to \(x^2xa=0\) by applying the QF again.

Best ResponseYou've already chosen the best response.0w^211w80 = 0 i find 2 numbers is 5 and 16 this only solution of W w> x^26x we have find x now w=16 and w=x^26x> x^26x=16 and also for 5 we solve this equation x^26x16=0 and x^26x+5=0 and we find x

Destinyyyy
