Which of the following is not a way to represent the solution of the inequality 3(2x - 1) greater than or equal to 4(2x - 3) - 3? x less than or equal to 6 6 greater than or equal to x A number line with a closed circle on 6 and shading to the left. A number line with a closed circle on 6 and shading to the right
help please
6*x - 3 >= 8*x - 15
12 >= 2*x
6 >= x
No, the last choice is correct
Tell us why...
it would be c
wait how is it c?
dont give the girl wron answers @cblrtopas its annoying
ok hold on lol
It's not wrong
ok....
could you both explain how you got the answer?
I simplified both sides of the inequality until I had x on one side and numbers on the other
well, your inequality looks like $$ 3(2x - 1) \ge 4(2x - 3) - 3 \implies 6x-3 \ge 8x-15 $$
The only answer that is not the right way to represent the solution is shaded circle at 6 with shading to the right...
now if you were to solve -> 6x-3 = 8x - 15 for "x" what would you get?
I.e. the last response
i woud get -2x=-12?
right, and x = 6, right?
yes
x is less than or equal to 6
ok, in an inequality is the same procedure, with the only difference that, when you multiply or divide or exponentialize by a negative number, like you just did now, you have to \(\color{red}{flip}\) the sign
yes i remember that u have to flip the sign
$$ 3(2x - 1) \ge 4(2x - 3) - 3 \implies 6x-3 \ge 8x-15\\ -2x \ge -12 \implies x \le 6 $$
so the answer would be the last choice?
|dw:1373148800458:dw|
|dw:1373148903985:dw|
???
see the solid line? see the shading?
yes
so, that's the \(x \le 6\)
ok
so wait im confused whats the answer
well, let's see the possible choices $$ \text{ A number line with a closed circle on 6 and shading to the} \color{red}{\text{ left}}\\ \\ \text{ A number line with a closed circle on 6 and shading to the} \color{red}{\text{ right}} $$ so, which one do you think?
the second one?
yes
its to the left but gl with that
ok the solution to the inequality is: x are all numbers less than or equal to the number 6.... Your question asks for what is the opposite of the solution to the inequality...essentially. The opposite of x <= 6 is of course x >= 6 and the statement: "A number line with a closed circle at 6 and shading to the right."
