8mL i'm pretty sure because you subtract 25.1 from 33.1
Domain is the years from 2000 through 2020 inclusive
<span>at 2000, t = 2000-2009 = -9 </span>
<span>at 2020, t = 2020-2009 = 11 </span>
<span>Domain: -9 ≤ t ≤ 11 </span>
<span>P(t) = 80(0.98)t </span>
<span>Since population models are almost always exponential, I'll assume you meant the "t" to be an exponent and the model should be: </span>
<span>P(t) = 80•0.98^t = 80 → t = 0 </span>
<span>The population is 80 at t = 0. The year corresponding to t = 0 is 2009</span>
Answer:
x = 9
y = 12
Step-by-step explanation:
-5x + 4y = 3
x = 2y - 15
Manipulate the equations such that the coefficients of two variables are additive inverses
-5x + 4y = 3
x = 2y - 15
Inverse operations
-> 4y - 3 = 5x
-> 2y - 15 = x (*(-5))
->4y - 3 = 5x
-> -10y + 75 = -5x
Now add the equations to eliminate a variable,
4y - 3 = 5x
-10y + 75 = -5x
-6y + 72 = 0
Inverse operations
-6y + 72 = 0
72 = 6y
/6 /6
12 = y
Back solve to find (x)
2y - 15 = x
2(12) - 15 = x
24 - 15 = x
9 = x
The integers that are greater than -6 and less than 5 are: -5, -4, -3, -2, -1, 0, 1, 2, 3, 4. Because it says greater/less than
