Answer:
x=-5
Step-by-step explanation:
-2x=3+7
or,-2x=10
or,x=-10/2
x=-5
Step-by-step explanation:
its .86 which is closer to .87
so choose the first one
In the 
plane, we have 
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the 
plane, we have 
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the 
plane, 
, so
which is a circle centered at (0, -10, 3) of radius 
.
Proportions are the comparison of two equal ratios. Therefore, proportional relationships are relationships between two equal ratios. So yes, it does matter.. I<span>nterval: all the numbers between two given numbers.</span>
