Novay_Z [31]

The true option about the solution to the system of inequalities shown is  B. The second line has a positive slope and goes through (0, negative 3) and (1, 0).

<h3>How to explain the inequality?</h3>

Plot these ordered pairs on a coordinate plane and connect them by straight lines.

The sign of both inequalities is "<"which means both lines are dotted and everything below the lines is shaded.

From the below graph it is clear that all values are satisfied.

Add the fractions together to find the portion who like basketball, soccer and football.

=1/3 + 1/8 + 5/12
need a common denominator (24)

=8/24 + 3/24 + 10/24
=21/24

simplify by 3
=7/8 like basketball, football & soccer

7/8 is the total for basketball, soccer and football. If 8/8 represents the whole class, then subtract 7/8 from 8/8 to find the number who like baseball.

=8/8 - 7/8
=1/8 of the remainder likes baseball


ANSWER: 1/8 of the students like baseball

Hope this helps! :)
