Answer:
The answer is B.
Step-by-step explanation:
To obtain the inverse of a relation you simply interchange the x and y coordinates of each pair.
Here:
(3,1) becomes (1,3)
(3,1) becomes ((1,3)
(7, -7) becomes (-7,7) and
(12, -15) becomes (-15, 12)
Answer:
A.
by the SAS postulate.
Step-by-step explanation:
We have been two triangles. We are asked to determine the theorem by which both triangles could be proven congruent.
We can see that side DF of triangle DEF is equal to side AC of triangle ABC.
We can also see that side BC of triangle ABC is equal to side EF of triangle DEF.
The including angle between sides AC and BC of triangle ABC is equal to the including angle between sides DF and EF of triangle DEF.
Since both triangles have two sides and their included angles equal, therefore, triangle ABC is congruent to triangle DEF by SAS (Side-Angle-Side) congruence and option A is the correct choice.
Answer:
0.8 hr = 0.8*3600 seconds = 2880 seconds
d = 30*2880 meters = 8640 meters
d = 8.64 km

.............................................................................................
Y^2 + y
y^2 + y + 0.25 <=== the constant term is 0.25
(y + 0.5)(y + 0.5) =
(y + 0.5)^2
to find the constant, u take half of ur y coefficient (not the y^2 coefficient)....y^2 + 1y....ur y coefficient is 1......half of it is 0.5....u then square it....(0.5^2) = 0.25 ....this is ur constant
