Answer:
not the matrix equation but this works
x=4, y=1
Step-by-step explanation:
2x-4y=4 (original equation)
2(3x+2y=14) (do this so that you can subtract or add- it's still equal)
2x-4y=4 (original equation)
6x+4y=28 (after multiplying)
8x=32 (add 2 equations together to cancel out 4y, can also subtract)
x=4 (division)
2(4)-4y=4 (substitution)
8-4y=4 (multiplication)
4y=4 (addition/subtraction)
y=1 (division)
Answer:
The value of the missing angle, x° is 115°
Step-by-step explanation:
The sum of the interior angles in a polygon is given by the formula (n - 2)×180, where, 'n', is the number of sides in the polygon
The number of sides in the given polygon, n = 10 sides
Therefore;
The sum of the interior angles in the polygon is (10 - 2)×180 = 1440°
The given angles of the polygon are;
107°, 126°, 325°, 125°, 95°, x°, 90°, 280°, 47°, and 130°
Therefore, we have;
107° + 126° + 325° + 125° + 95° + x° + 90° + 280° + 47° + 130° = 1440°
x° = 1440° - (107° + 126° + 325° + 125° + 95° + 90° + 280° + 47° + 130°) = 115°
The value of the missing angle, x° = 115°.

Answer:
1. (-3,2) and (-1,2)
Step-by-step explanation:
Reflection over x axis results in change y-coordinates to opposite sign and x-coordinates remain as is
<u>So the coordinates become:</u>
- A(-3, -2) → A'(-3, 2)
- B(-1, -2) → B'(-1, 2)
Correct option is the first one
