Answer:
b = 28/3 or 9.3
Step-by-step explanation:
b-8+2b=20
3b-8=20
3b=20+8
3b=28
Answer:
yes, i agree. the right angle is 90 and 90+90=180. The law of the congruent angle states that if one angle in a the plane is right then the other connected must be as well, making line L 180.
Step-by-step explanation:
i badly explained it however you should get the answer correct with that. i think... use your brain in addition to mine.
Answer: B' is (3, -3)
Step-by-step explanation:
When we have a point with coordinate (x, y) and we do a dilation (around the center) with a scale factor of A, the coordinate of the new point will be:
A*(x,y) =(A*x, A*y)
Here our point is (1, -1) and the factor is 3, so the new point will be:
(3*1, 3*-1) = (3, -3)
