y = 2x
Month Height
1 2 ft
2 4 ft
3 6 ft
4 8 ft
and then, plot these points on the graph:
(1,2) ... (2,4) ... (3,6) ... (4,8) ...
<u>Answer</u>:
The coordinates of point C' are (4, -2)
<u>here's</u> <u>why</u>:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y). So if we use this information with the problem, the original coordinates, (-4, -2), the new coordinates will be (4, -2).
Hope this helped.
Answer: 3
Step-by-step explanation:
V=whl
9x+13=2x+48
-2x -2x
7x+13=48
-13 -13
7x=35
/7 /7
x=5
y=9(5)+13
y=45+13
y=58
The answer to this problem is 12.
