Answer:
x = 17.2
Step-by-step explanation:
since they are supplementary, when you add then together they equal 180
4x + 8 + 6x = 180
Combine like terms
10x + 8 = 180
subtract 8 from both sides
10x = 172
divide each side by 10
x = 17.2

Answer:
(2/3, 8/3)
Step-by-step explanation:
Using the line segment equation we get: (x,y)=(-6+2/3(4-(-6)), -4+2/3(6-(-4))=(2/3,8/3)
(b)
The 50 degree angle and angle b are vertical angles, which means they are congruent.
The 50 degree angle and angle c are a linear pair, which means that they are supplementary/add up to 180 degrees.
Angles a and c are vertical angles, which means they are congruent.
a = 130
b = 50
c = 130
(c)
The 90 degree angle and angle b are vertical angles, which means they are congruent.
The 50 degree angle and angle c are vertical angles, which means they are congruent.
The 50 degree angle, 90 degree angle, and angle d all form a line, which means that they are supplementary and add up to 180.
Angle d and angle a are vertical angles, which means they are congruent.
a = 40
b = 90
c = 50
d = 40
(e)
The measure of a circle is 360 degrees. These three angles form a circle, so therefore if we add them all up, they will equal 360 degrees.
3a + 4a + 5a = 360
12a = 360
a = 30
(f)
The measure of a circle is 360 degrees. These four angles form a circle, so therefore if we add them all up, they will equal 360 degrees.
3a + 4a + 5a + 6a = 360
18a = 360
a = 20

Answer:
y = x+2
Step-by-step explanation:
(x1,y1) is (-4,-2) and (x2,y2) is (2,4)
Slope intercept form is y = mx+b
m = slope
b = add on
Slope = 
Substitute numbers
Slope = 
Two negatives = one positive
Simplify
The slope is 1
We can substitute y, x, and the slope
4 = 2*1 + b
4 = 2+b
b = 2
Slope intercept form is y = mx+b
Answer is y = x+2
Hope this helps :)
