Answer:
2
Step-by-step explanation:
Look here!
9x + 4= 5x + 20 (alternate interior angles)
9x-5x =20-4
4x = 16
x= 16/4
x= 4
No, it's not.
15/28 equals to (about) 0.54 while 25/45 is (about) 0.56.
They are close, but not equivalent.<span />
Answer:

And replacing the value of
we got:

Step-by-step explanation:
For this case we have the long who represent the height 10 cm and the diameter is 6cm. So then the radius is given by:

And the surface area for a cylinder is given by this formula:

And replacing the info given we got:

And replacing the value of
we got:

Graph 1: y= -3/4, which means its (x,y) coordinate is (0, -3/4).
Graph 2: y= 3/4, which means its (x,y) coordinate is (0, 3/4).
Graph 1 would be the point -3/4 on the y-axis, while graph 2 would be the point 3/4 on the y-axis.
Therefore, graph 1 and graph 2 are symmetrical about the x-axis.
Hope this would help~
