100 balloons × 4 Minutes = 400minutes
400minutes ÷ 5people = 80 ...so 80 minutes is your answer.
Answer:
The correct options are;
1) "Greater/Less than or equal to" means the circle on the number will be SOLID
2)"Greater/Less than" means the circle on the number will be open
3) If It is "greater than", the line will be colored to the RIGHT of the number & if it is "less than", the line will be colored to the LEFT of the number line
Step-by-step explanation:
When a linear inequality is graphed on a number line, and the value of the inequality is "less than" or "greater than" the limit displayed on the number line, the limit of the inequality is indicated by an open
When the the limiting value of the inequality is specified as "less than or equal to" or "greater than or equal to" the value displayed on the number line as a SOLID circle.
The region where the inequality is valued on the number line is the colored region.
a² - b² = (a - b)(a + b)
49x² - 9 = (7x)² - 3² = (7x - 3)(7x + 3)
Step-by-step explanation:
using set notation
domain (-infinity, infinity)
range(-infinity, 3]
the domain is from negative infinity to infinity
the range is from negative infinity to three
