y = 3(-x - 2)
Any horizontal transformations or reflections you make to y = x must be within the parentheses.
We have a + b = 180 and a = 12 + b;
Then, 12 + b + b = 180;
12 + 2b = 180;
2b = 168;
b = 84;
a = 12 + 84;
a = 96;
Answer:
158.4 degrees.
Step-by-step explanation:
A line is 180 degress in total so subtract 21.6 from 180. Then you get 158.4
1.4 repeating?
3x+3=5x-10+7x
3x+3=12x-10
3=9x-10
13=9x
1.4 repeating=x
Because 1 * 21 = 3 * 7 ( 21 = 21 ) , 1/3&7/21 form a proportion.
