Answer:
-4 y>-2/3x-4
Step-by-step explanation:
-3y>2x+12 y> -2/3x-4
Okay, the first thing to do is to make it so you're multiplying everything instead of dividing by that last fraction. To divide by a fraction, you just multiply by its reciprocal. So then, it's 15/124 x 230/30 x 124/230. After that, let's organize it into one single giant fraction since order of operations allows us to arrange division and multiplication however we want. Then it's 15x230x124 / 124x30x230. Then, you'll notice that the 230s and 124s can both be canceled out, leaving 15/30. After simplifying, your final answer is 1/2.
You're correct: the logical OR operator is true whenever one of the two options is true.
So, the sales of shoes OR socks is given by the 52 and 9%, which together evaluates to 
I don’t know for sure if this is right but I got f(-3)=1.
f(-3)= -x - 2
f(-3)= -(-3) - 2
The 2 negatives cancel each other out and make a positive.
f(-3)= 3-2
f(-3)=1
