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).
2x + 3y = 36
2x + 3*6 = 36
2x + 18 = 36
-18 -18
___________
2x = 18
/2 /2
___________
x = 9
Answer:
-6°
Step-by-step explanation:
x(original temperature)
t (time)
r (rate)
original x-(r×t)
Q) x-(2×-3)
=x-6
Step-by-step explanation: When the equation of a line is written in the form "y = a number," that line is a horizontal or flat line.
For example, y = 1, y = 8, and y = 96 are all horizontal lines.
Parallel lines have the same slope so any line
parallel to "y = a number" will also have a slope of 0.
