4

Step-by-step explanation:

Let b represent the number of birds. Then the cost of care for b birds and 16-b cats was ...

4.50b +6.50(16-b) = 96.00

-2.00b = -8.00 . . . . . . . . . . . . simplify, subtract 104

b = 4 . . . . . . . . . . . . . . . . . . . . .divide by -2

The number of birds at the shelter on Thursday was 4.

y=mx+b

step-by-step explanation:

m slope, b y-intercept

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
