Mathematics

Answer:

(- 3, 4 )

Step-by-step explanation:

x + y = 1 ( subtract x from both sides )

y = 1 - x → (1)

2x - y = - 10 → (2)

Substitute y = 1 - x into (2)

2x - (1 - x) = - 10 ← distribute parenthesis and simplify left side

2x - 1 + x = - 10

3x - 1 = - 10 ( add 1 to both sides )

3x = - 9 ( divide both sides by 3 )

x = - 3

substitute x = - 3 into (1)

y = 1 - (- 3) = 1 + 3 = 4

solution is (- 3, 4 )

Find the area of the shaded polygons<br> PLS HELP ASAP AGAIN!!!
Rama09 [41]

Answer:

  9 square units

Step-by-step explanation:

Pick's theorem is a useful relationship in circumstances like these. It tells you the area is ...

  A = i + b/2 - 1

where i is the number of interior points (8), and b is the number of points on the border (4).

The area of this figure is ...

  A = 8 + 4/2 -1 = 9

The area of the polygon is 9 square units.

_____

You can also get there by realizing the bounding rectangle is 4 units square. From that, corner triangles are cut. CW from upper left, those triangles have (base, height) dimensions of (3, 2), (1, 3), (3, 1), and (1, 2). So, the total of their areas is (1/2)(6 +3 + 3 +2) = 7 square units. The shaded area is then 16-7 = 9 square units, same as above.
