Which representation of a transformation on a coordinate grid does NOT preserve congruence? O (x, y) -> (12x12y)
O(xy) --> (x, y)
O(x, y) -> (x + 12, x - 12)
(xy) -> (x, y)

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

b.
