Solve the system if equations by subtracting:
We get 5L = 45
L = 9
Substituting for L in s = 20L + 75 gives s = 255
So the second choice I the correct one
Answer:
9

Answer:
No, they are not
Step-by-step explanation:
The rate can be described in terms of absences per day.
Now in the first 30 days, they were 17 absences. The rate would thus be number of absences divided by number of days and that is 17/30
In the second run, there were 42 absences in the recent 60 days, rate here would be 42/60 and that is 21/30
Thus, the rates are not equivalent
Answer:
option (a) y=|x-4| is correct.
Step-by-step explanation:
Solve the question by elimination method i.e. put values of x in the given equations and check if equality holds.
(b) if x=2, then y= |2| - 4 = -2 , which is wrong
(c) if x=2, then y = |2| + 4 = 6, which is wrong
(d) if x= 2, then y = |2 + 4| = 6, which is wrong
The equality holds for (a).
