Which point gives the minimum value p3x-2y in the feasible region shown?

If you want to ask questions about the "region shown", then it would have helped if you could make sure that there is some region that is shown. However, given the limitations of the browser used by this site, you do not have much of a hope!


What exponent are all numbers are understood to have?

1, if the exponent is not shown.


What is the equal to or greater then symbol on a graph?

If the graph is a two-dimensional plane and you are graphing an inequality, the "greater than or equal to" part will be shown by two things: (1) a solid, not a dotted, line--this part signifies the "or equal to" option--and (2) which region you shade. Shade the region that contains the points that make the inequality true. By shading that region, you are demonstrating the "greater than" part.


Which property of addition is shown by 7 3 5 7 3 5?

Well, honey, those numbers are just showing the commutative property of addition - it doesn't matter what order you add them in, the sum remains the same. So whether you add 7 + 3 + 5 or 5 + 3 + 7, you still end up with 15. Math is like a good recipe, as long as you follow the steps, you'll get the right result.


How come you change a division sign into a multiplication sign for dividing fractions?

Flip the fraction around (the one after the division sign) and change it to a multiplication sign. (swap the numerator with the denominator) so 2/(3/10) = 2*(10/3) The reason you do so is if you think of multiplication and dividing revolving around the number 1, in multiplying if you are above 1 then you are increasing if you are lower you are increasing. The opposite is the same of division. Effectively, if you think about it multiplication is the inverse of division and the other way around as well, so by flipping the fraction you are inverting it, so instead of dividing by 0.5 you multiply by 2. I hope this makes sense, it could be shown algebraically, but it is probably easier to understand this way.
