To do 4x> 12, you divide 4x by 4 to isolate variable then divide 12 by 4, because if you do something on one side you have to do on the other so... x= 3 ..hope that helped . Also 75% of 96 Its 72.. its just 75/100 = x/96 then use cross products to find out that
Answer:
the second one........the shape of the conic section os circle
The relationship is linear because x is increasing at a constant rate of 6, and y is decreasing at a constant rate of 3.
The equation of the line is y+4=-1/2(x-1).
The answer is A
Find

where

<span>So to find the left sided limit, you need to plug in -8, into x+9
and to find the right sided limit, you need to plug in -8, into -7-x.
</span>
<span>If the two sides of the limit are no equivalent, then </span>

Since both sides are equal to 1, the limit is 1.
