For every 7 glasses wearers in a classroom, there are about 13 non glasses wearers. if there are 32 students in a entire class how many students are non glasses wearers

21 With glasses

Step-by-step explanation:

32/20=1.6

1.6•7=11.2 Without Glasses

1.6•13=20.8 With Glasses

20.8 rounded to nearest whole number=21

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
