Answer:
C
Step-by-step explanation:
If you use substitution, you will figure out that x=350-y, and 3x=1050-3y. If you plug this into the equation, 1050-3y+7y=2050.
Simplifying, we get 1050+4y=2050, and 4y=1000.
Divide each side by 4 to get y=250.
The number line shows two points with coordinates negative 11 and positive 7.
A.
|–11 – 7|
B.
|–11 + 7|
C.
|7 – (–11)|
D.
–11 – 7
The measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees
Solution:
Given that exterior angle of triangle is 140 degrees
The exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles
Given that adjacent angles are congruent
Let one of the non adjacent interior angles be "x"
x + x = 140
2x = 140
x = 70
So the two interior angles are 70 degrees and 70 degrees
Let us find the third interior angle
The angle sum property of a triangle states that the interior angles of a triangle always add up to 180 degrees
70 + 70 + third angle = 180
third angle = 180 - 70 - 70
third angle = 180 - 140
third angle = 40 degrees
Thus the measures of all of the interior angles of the triangle are 70 degrees, 70 degrees and 40 degrees
-3+2 / -5+-1 /6+-4 / -2+-7
Answer: -3+2 = -1 / -5+-1 = -6 / 6+-4 = 2 / -2+-7 = -9

Answer:
The slope intercept is y=mx+b
y=-1x (you go down one over one from your y-intercept)
y=-1x-1 (It would be minus one because that is where it crosses the y-axis)
