Question: Match them whether or not they are identities My reasoning: My reasoning to figure this out is to simply choose whatever value I'd like for a and b, then plug in it to the equation. The reason I am doing that is because "An identity is an equation true for all values of the variable". So then when I simplify/solve the equation, if they equal then I know it's an Identity, and if they dont equal then they're now an identity. (I chose a to equal 2 and b to equal 4, and did the work on a separate piece of paper)

Does that reasoning make sense? Because I've been on this slide for like 30 mins and it says I still havent sorted all the cards correctly .

Would really appreciate some help, thank you. (The photo is what I sorted, but still some are not sorted correctly.)​

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
