Answer:
y = -x+5
Step-by-step explanation:
slope intercept form

and the y intercept is 5 ( 0,b)
y = -1x+5
y = -x+5
Answer:
370
Step-by-step explanation:
The venn diagram corresponds to students who were sick in January at a Chicago high school.
Students who had only fever= n(A) = 80
Students who had only headache= n(B) = 90
Students who had only cough = n(C) =60
Students who had both cough and fever = n(AC) = 10
n(AB) = 40:n(BC) = 30 n(ABC) = 20
Hence total students = 800
no of students who were absent due to other reasons = 100
REmaining students = 700
Students who were sick = sum of all =330
So no of students who were at school = 700-330 = 370
