Answer:
-2y
Step-by-step explanation:
Let's simplify step-by-step.
x−y−(x+y)
Distribute the Negative Sign:
=x−y+−1(x+y)
=x+−y+−1x+−1y
=x+−y+−x+−y
Combine Like Terms:
=x+−y+−x+−y
=(x+−x)+(−y+−y)
=−2y
Given that x=number of days
To model the expressions we use the exponential growth given by:
y=a(b)^nx
where:
a=initial value
b=growth factor
n=24 hours
thus Colby's experiment will be:
y=50(2)^(1/2*24*x)
y=50(2)^(12x)
N/B we multiply by 24 so as to convert days into hours
b] <span>Jaquan's starts with 80 bacteria that double every 3 hours.
a=80, b=2
thus
y=80(2)^(1/3</span>×24×x<span>)
simplifying the above we get:
y=80(2)^(8x)</span>

I already answered
2(x + 1) – (–x + 5) ≤ –18
2x + 2 + x - 5 <= -18
3x - 3 <= -18
3x <= -18 + 3
3x <= -15
x <= -15/3
x <= -5
Answer: its 130 degrees
Step-by-step explanation: if you reflect it over the line and translate it up a little to be on top of the other image it will be the same and have 130 degrees in the same spot
Answer:
64
Step-by-step explanation:
80*0.2
16
80-16 = 64
