manager estimates the shelter's daily
expenses, assuming there is at least one dog
in the shelter, using the function E(x) = 30 +
2.40x.
Which statements regarding the function E(x)
are correct?
1. x represents the number of dogs at
the shelter per day.
II. x represents the number of
volunteers at the shelter per day.
III. 30 represents the shelter's total
expenses per day.
IV. 30 represents the shelter's nonfood
expenses per day.

Step-by-step explanation:

it represent the cost of a dog each day and they have about 30 dogs

Statements I & II

Step-by-step explanation:

If each dog costs about $2.40 in food expenses than you would multiply that by the number of dogs you have. So x represents the possible number of dgos.

The 30 represents the other daily expenses that the shelter has to each day.

i can answer this question sweetie!

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
