Lin was looking at the equation 2x-32+4(3x-2462)=14x. she said”i cant tell right away there are no solutions, because on the left side, you will have 2x+12x and a bunch of constants, but you have just 14x on the right side.” do you agree with lin? explain your reasoning.

When an equation don't have solution, it's because variables are cancelled or eliminated.

In this case, if we operate left side, we will have a term 14x, and the right side of the equation there's also 14x, that means that variable will be eliminated, like this:

As you can see, the equation ends in a false result, that means it doesn't have any solution, and we can tell by just seeing the first line of the equation like Lin says.

So, totally disagree with Lin, she can tell from the beginning that the equation doesn't have a solution.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

any options?
