F(t)= 7.00 x t + 55
A reasonable domain is (0,1,2,3).
The range is ($55,$62,$69,$76)
A) 2007
b) 120
c) the donations are decreasing as years increase
The question can't be solved because we can't have negative sign under square root
Step-by-step explanation:
2x+3y=23 2x+3.7=23 2×1 + 3×7 = 23
3y= 23 2×+21= 23 2 + 21 = 23
23÷3 = 7 2x= 23-21
y=7 2x= 2
x= 1
5x+3y=17 5×4+3y=17
5x=17+3 20+3y=17
5×=20 20=17+3y
14÷5 = 4 20=20+y
x=4 y=20-20
y=0
