143o
interior angles of a triangle always add up to 180o
Answer:
The slope would be 2
Step-by-step explanation:
Your slope-intercept form is always y=mx + b
The <em>b </em>is always your <em>constant</em>
The <em>mx </em>is your <em>slope</em>
The<em> y </em>is your<em> output</em>
The correct answer for the problem above is -23 .
Explanation
1. collect the like terms
2x + x - 11 + 3 - 7x = 15
2x , x , & -7x are like terms
-11 & 3 are like terms
2x + x -7x = -4x
-11 + 3 = -8
2. Move constant to the right-hand side and change its sign .
-4x = 15 + 8
-4x = 23
3. Make the signs on both sides of the equation
-4x = 23 turning into 4x = -23
answer =
4x = -23
Answer:
<em>Y = -4/3</em>
Step-by-step explanation:
Subtract 1 from -1/3.
Y = -1/3 - 1
Y = -1/3 - 3/3
Y = -4/3
