3x+3y=33 notice how in the bottom equation you can multiply y by 3 to get
2x+y=19 what is on top. This sets you up for an easy case of elimination! Multiply everything on the bottom by -3 to start.
3x+3y=33 Then you can cross out the y's (because they're opposite) and
-6x-3y=-57 combine equations
-3x=-24 From there it is pretty straight forward to find x: Just divide -24 by -3
x=8 Then plug it back into any of your original equations and find y
3(8)+3y=33 You should find that y=3
Answer:
A. 12 only.
Step-by-step explanation:
We have been given a graph of a function. We are asked to find the value of 
.
The will be the point, where our given graph crosses y-axis.
Upon looking at our given graph, we can see that our graph crosses y-axis at 
.
Therefore, 
and option A is the correct choice.

As the word suggests, a quarter-sphere is a quarter of a sphere, and thus the volume of a quarter-sphere is a quarter of the volume of the sphere.
The volume of a sphere is computed as
So, the volume of a quarter-sphere is
