It
is very easy to find the values for a, b, c, d and e. All you have to
do is use the Algebra vs. Geometry table to use the given values to
find the rest. Please see attachment to see the table. For example if
we want to find e we simply subtract 53 from 75. This way e = 22,
then use this to find the next value which will be b.
Let x be the number of students that like both algebra and geometry. Then:
1. 45-x is the number of students that like only algebra;
2. 53-x is the number of students that like only geometry.
You know that 6 students do not like any subject at all and there are 75 students in total. If you add the number of students that like both subjects, the number of students that like only one subject and the number of students that do not like any subject, you get 75. Therefore,
For the answer to the question above, z=6-(3/4)y-2x <span>z+(3/4)y+2x=6 </span>
<span>Just by connecting the three points on the graph, I got this equation by isolating each plane to figure it out. This equation only explains the plane bounded by these three points, though, so to draw it just plot the points and connect them.</span>
