c. t = 18h
is the appropriate expression for t equals 18 times h.
D (2 and 4), vertical angles oppose eachother, and are always congruent (identical).
Answer:
B) Isosceles
Step-by-step explanation:
The given triangle has vertices at A(-1,2), B(4,2) and C(3,-1).
We must first determine the length of the sides of the triangle, before we can classify it.
We apply the distance formula to find length of the sides.




.
The length of side BC




The length of side AC

We simplify to obtain;





Since
, the given triangle is an isosceles triangle.
The correct answer is
Answer:
Y = -1/2x + 7/2
Step-by-step explanation:
slope = -1/2
