Step-by-step explanation:
6x-12=x+3
6x-x=3+12
5x=15
x=15/5
x=3
Answer:
Volume of the similar sphere be 64 :343 .
Option (D) is correct.
Step-by-step explanation:
Formula
As given
The volumes of two similar spheres given that the ratio of their radii is 4:7 .
Let us assume that the x be the scalar multiple of the radi .
Radius of first sphere = 4x
Radius of second sphere = 7x
Putting the values in the formula
Thus
Therefore the ratio of the volume of the similar sphere be 64 :343 .
Option (D) is correct .
Answer:
The 3rd answer is correct!
Step-by-step explanation:
The figure is being reflected over the x axis (horizontal axis). Any y coordinate that is negative becomes positive, and vice versa. The x coordinate stays the same.
If we have some point (x,y) as the original point, then it would turn into (x,-y). Note how the y coordinate has a negative on it now.
So we can say
which is what choice C is saying.
Choice C is the answerChoice D is NOT the answer because the words "y axis" under the 'r' should be "x axis" instead.
