Answer:
26°,51°,103°
Step-by-step explanation:
sum of angles=180°
C. mate, mate, mate, i don't know man, imagine the -1 + 0.8 with out the negative in front of 1, 1- 0.8, you get 0.2, then add the negative back to make it negative 0.2. so c
all are linear eqns since they follow the formula y = mx + c
1) y = 2x +15
2) 2x -4y = 12 can be rewritten as...
4y = 2x -12 =》 y = 1/2 x - 3
3) 2x - 2y = 12 can be rewritten as...
2y = 2x - 12 =》 y = x - 6
4) 3z -4x =18 can b rewritten as...
3z = 4x - 18 =》 z = 4/3 x - 6
X^2 - 2x - 3 = 0
(x^2 - 2x + ) - 3 - = 0
(x^2 - 2x + 1) - 3 - 1 = 0
(x - 1)^2 - 4 = 0
(x - 1)^2 = 4
