26 + 6b ³ 2(3b + 4) A. all real numbers B. b £ C. b ³ D. no solutions
wow i see the problem the inequality you see is being replaced, when you copy and paste, by that little 3
what do you actually see on the computer?
I see the little 3 in my question on the test
hmmm then maybe it is your browser it should be either \(\geq\) or \(\leq \) i think
maybe you can try a different browser i can tell by the question that they want you to solve an inequality of some kind, but i cannot tell whether it is \(\leq \) or \(\geq\)
Well skip that one
you have the little 3 twice, and also that other symbol, so your browser is not reading the script properly it really doesn't make any sense
Solve the equation. Check for extraneous solutions. 2|7-7x|=2x+4
try chrome or firefox
im on firefox
\[2|7-7x|=2x+4\] divide both sides by 2 and get \[|7-7x|=x+2\] or to make it easier \[|7x-7|=x+2\]now you have to solve two equations \[7x-7=x+2\] and also \[7x-7=-x-2\] can you solve these?
No... :/
really? damn ok lets do this one \[7x-7=x+2\] you want to get \(x\) by itself so subtract \(x\) from both sides and get \[6x-7=2\]then add 7 to both sides and get \[6x=9\] and finally divide both sides by \(6\) to get \[x=\frac{9}{6}=\frac{3}{2}\]
try this one \[7x-7=-x-2\] this time you want to ADD \(x\) to both sides, then add 7 to both sides, then divide by \(8\)
x=5/8
you found it! so the two solutions are \[x=\frac{5}{8}\] or \[x=\frac{3}{2}\]
