Answer:
-2
Step-by-step explanation:
15x+6=6x-12
15x-6x=-12-6
9x=-18
x=-2

For the statement to be true, 'a' and 'b' must be equal
*First expand the binomial using FOIL, then set it equal to whats given "2abi".
Then you can find the relationship between a and b.
Answer:
they are congruent so 47 is also the measurement for its corresponding angle(aka the corner that doesn't have a variable)
and in a triangle, interior angles add to 180 so 47+x+y=180
90 + 43 = 133
+47= 180
so your answer is a
hope this helps!!
A reflection across the x-axis has the rule:
(x,y)→(x,-y).
Then:
- A(-1,-1)→A'(-1,1),
- B(0,1)→B'(0,-1),
- C(4,2)→C'(4,-2),
- D(6,0)→D'(6,0),
- E(3,-3)→E'(3,3).
Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
