Answer:
a=2
Step-by-step explanation:
Slope is found by (y2-y1)/(x2-x1)
Using the points, that is (5-a)/(4a-2) = 1/2
multiply both sides by the denominator 4a-2
5-a = (1/2)(4a-2)
5-a=2a-1
put like terms on opposite sides by adding a to both sides so a terms on the right, adding 1 on both sides so numbers are on the left
6=3a
divide both sides by 3
a=2

Answer:
D. 10 square root 3 is your answer
Step-by-step explanation:
Here is what you do.
<em>square root 30 = 3 x 2 x 5 </em>
<em>square root 10 = 2 x 5</em>
Add them together.
<em>3 x 2 x 2 x 5 x 5 </em>
<em>3 x 4 x 25.</em>
4 and 25 can come out of the square root.
<em>2 x 5 = 10</em>
10 square root 3 is your answer.
Answer: x=35
The supplementary angle with 40 and 40 degrees tells me the triangles angle is 100 degrees (40 + 40 + 100 = 180 degree)
2x + 30 = 100
-30 -30 subtract 30 from both sides
___________
2x = 70 Divide both sides by 2 to isolate x
X = 35
