1) -149, -1; -148, -2; -147, -3
2) No, according to the commutative property of addition, it does not matter the order they are put in.
Hope this helps!
Answer:
72
Step-by-step explanation:
2*-5=-10
-10*-6=60
60-(-12)=60+12=72
1- not a function; 3 in the domain is repeated
2- a function
3- a function

Answer:
1. y= 25400(1 + 0.11)^x
2. 2019
Step-by-step explanation:
1. y = a(1 + r)^x <em> </em>
<em>(exponential growth formula :</em>
<em>a = initial value (the amount before measuring growth or decay)
</em>
<em>r = growth or decay rate (usually represented as a percentage and expressed as a decimal)
</em>
<em>
x = number of time units that have passed)</em>
y= 25400(1 + 0.11)^x
so in 1 year, in 1996, we would say
y=25400(1+0.11)^1
y=25400(1.11)
y=28194
2. I found the answer by plugging in numbers into x
with x = 24
y= 25400(1+0.11)^24
y= 310874
so in 24 years, the population will surpass 302438 which would be 1995+24= 2019
<span>t/(t-8)=(t+8)/30
(t+8)(t-8) = 30t
t^2 - 8^2 = 30t
</span>t^2 - 30t - 64 = 0
<span>(t-32)(t+2) = 0
so t = 32 and t = -2
answer: 2 solutions </span>t = 32 and t = -2<span>
</span>
