Ahh yes, negative exponents always give us a scare once and a while. All the negative means is to flip the position of its base. For instance, if x has a negative exponent and x in the denominator, all you would have to do is move x to the numerator with the same power (except it's no longer negative). Before we substitute x and all the other variables which the values given, let's eliminate the negatives first.
After flipping positions/eliminating the negative exponents it should look like this:

which simplifies to

now that everything is simplified, and all negative exponents are eliminated we can substitute x with 2, and y with (-4).

which simplifies to

Answer:
532m squared is the answer
Step-by-step explanation:
Split the shape into two shapes
one will be a square and the other one a triangle
1) since the length and the width of the square is 18m just Multiply
18x18=324m squared
2) look carefully the width of the square you split is equal to the base of the triangle, so you connect the 18 and the 8 together.
18+8=26m squared
3) Now solve the triangle since you know the height which is 16m squared.
A=lw/2
26x16=416
416 divided by 2 is 208
4) finally just Add
208+324=532m squared

Answer:
y = - 1/2x - 4.5
Step-by-step explanation:
Step 1:
x + 2y = - 9 Equation
Step 2:
2y = - x - 9 Subtract x on both sides
Answer:
y = - 1/2x - 4.5 Divide 2 on both sides
