Question

An illusionist needs up to 10 volunteers for a show. She needs no fewer than 4 female volunteers. Let x represent the number of female volunteers and y represent the number of male volunteers.

Which inequalities model the situation?

Choose exactly three answers that are correct.

A- x + y < 10
B- x + y ≤ 10
C- x > 4
D- x ≥ 4
E- y > 0
G- y ≥ 0

Answer 1

The answer is

x ≥ 4

x + y ≤ 10

y ≥ 0

Answer 2

For the answer to the question above,

B- x + y ≤ 10 => up to 10

D- x ≥ 4 => no fewer than 4

G- y ≥ 0 => x no fewer than 4, could be up to 10, then y=0
