Step-by-step explanation:
The sum of adjacent angles traversed by a line must equal 180 degrees.
128+x=180
x=52
It's the first one because all the y's are the same number. That means that when you graph the chart you would get a horizontal line. Horizontal lines on graphs always have a slope of zero....unlike a verticals slope is undefined.
Answer:
x = 3
Step-by-step explanation:
Write equation.
4x + 6 = 18
Subtract 6 from both sides.
4x = 12
Divide 4 to get x alone.
x = 3
