Hello!
Your "8 x 4 x 2/8 x 7" needs a bit of work to become clear. Please use " * " to indicate multiplication, not " x, " which used to represent an unknown quantity.

2
(8 x 4 x 2/8 x 7_ => (8*4* * 7) is my interpretation of what you typed.
8

This simplifies to (4*2*7), or (56).

Would you please treat "8^0/7^-3" in the same way. For 7^-3 please substitute:

1
7^(-3) or
7^3
1
Similarly, your "7^-9" should be rewritten as 7^(-9) or
7^9.

Try to get all of your exponents to be +

See what you can do with this info. If you write back I'd be happy to comment.

Answer from: Quest

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.
