Answer:
a)  The arithmetic sequence with common difference 2 that has 8 as the first term.
b) The arithmetic sequence of common difference -5 and first term 15.
Step-by-step explanation:
Let's use for example the arithmetic sequence with common difference 2 that has 8 as the first term. Then the first two terms of this sequence are:
8, and (8+2) = 10 Therefore the second term is 10.
Another arithmetic sequence of common difference -5 and first term 15. The firs two terms of this sequence are:
15, and  (15 - 5)  = 10. Therefore again a 10 as second term.

Answer:
Isosceles triangles have two sides with the same length, and one side that ... Similarly, if two angles of a triangle have equal measure, then the sides ... (2) Set up an equation and solve for x. ... x = 60/2 x = 30. Each base angle of triangle ABC measures 30 degrees. ... In isosceles triangle RST, angle S is the vertex angle.

Answer:
C.   (x, y) → (x, -y)
Step-by-step explanation:
The algebraic representation that correctly describes a reflection over the x-axis is (x, y) → (x, -y) 
Here's an example to show understanding 
Plot A is (4,6) and the reflection over the x-axis would be (4,-6)
