Answer:
B
Step-by-step explanation:
Using the pythagorean triples: 3,4,5 you can determine the third side.
Using a right triangle you have a hypotenuse of 5, the height of the triangle would be 4, so then the base would be 3 but you have two right triangles together so you have to double it which equals 6.
Answer:

Step-by-step explanation:
You just need to take a couple of points from the graph and apply the slope formula.

Answer:
72 / 5
Step-by-step explanation:
( 12 / 5 ) + ( 6 / 5 )
= ( 12 + 6 ) / 5
= 18 / 5
[ ( 12 / 5 ) + ( 6 / 5 ) ] / ( 1 / 4 )
= ( 18 / 5 ) / ( 1 / 4 )
= ( 18 x 4 ) / 5
= 72 / 5
I would like more information please. What line are you referring to?
Answer:
6t = -21
Step-by-step explanation:
3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:
3t -5t -7 +7 = 5t-5t+7
-2t = 7
t = -7/2
Then 6t = 6*-7/2 = -21
