Answer:
9) e=-40 10) k=9
Step-by-step explanation:
9) e/4-10=-20 add 10 on both sides
e/4=-10 Multiply everything by 4
e=-40
10) 0.4k-4+1.6k=14 combine like terms
2k-4=14 Add 4 on both sides
2k=18 divide both sides by 2
k=9
Direct variation is is when the x and y a direct relation
without constants added or subtracted
With being times by each other
so the only one that meets the definite is the first one
y = 0.5x means y is equal to half of x. So you know that every y is directly related to half of x
Answer:
The population of interest is all the students at the University, to find their parking times.

Here, the population of interest is all New York state residents.
An administrator inconspicuously followed 250 students and carefully recorded their parking times.
Sample of 250 students at the University.
So the population of interest is all the students at the University, to find their parking times.
You'd take the 1 and separate it from the 3/4
