Answer:+21
Step-by-step explanation:
21 + 0
The answer is D. 12
To find this you would add (5x+16) and (9x-4) and set them equal to 180, because angles on a straight line add up to 180:
5x+16+9x-4 = 180
Then you would solve that for x, and would get x=12
Hope this helps!

Answer:
Y = x - 9
Step-by-step explanation:
A slope of 1 = x
So we have
Y = x
To find y intercept we do
7 - (-2) = 9
So we have a y-intercept of 9
Y = x - 9
Answer:
9x + 5y
Step-by-step explanation:
Here, in 2x + 5y+ 7x, the 'like terms' are 2x and 7x, and the sum of these terms is 9x. Thus, 2x + 5y+ 7x becomes 9x + 5y.
