Answer:
Adult tickets=275
Step-by-step explanation:
form 2 equations from the given info.
x+y=611
y=x+61
x being the adults and y being the students tickets
then substitute the y equation into the first equation.
x+x+61=611
2x+61=611
2x=550
x=275
and you can check by putting 275 back into the original equations :)
Answer:
Step-by-step explanation:
Hi student, let me help you out!
<u>.............................................................................................................</u>
<u></u>
First, let's recall the slope formula: 
, where y2 and y1 are y-coordinates; x2 and x1 are x-coordinates.
Plugin the values: 
.
Upon simplifying, we obtain 
.
Upon simplifying this further, we obtain 
.
0 divided by anything results in 0.
✨ ∴, the slope of this particular line is 0, and this line looks something like this: 
.
See, it's a horizontal line, with a rise of 0, meaning that it goes up 0 units.
Hope this helped you out! Ask in comments if even the slightest queries arise.

Answer:
See below ~
Step-by-step explanation:
<h3>What is the rat population in 1993?</h3>
⇒ Number of years since = 0 ⇒ <u>t = 0</u>
⇒ Apply in the formula
⇒ n(0) = 73e^(0.02 × 0)
⇒ n(0) = 73e⁰
⇒ n(0) = 73,000,000 rats
=============================================================
<h3>
What does the model predict the rat population was in the year 2009?</h3>
⇒ Number of years since 1993 : 2009 - 1993 = 16 ⇒ <u>t = 16</u>
⇒ Applying in the formula
⇒ n(16) = 73e^(0.02 × 16)
⇒ n(16) = 73e^(0.32)
⇒ n(16) = 73 × 1.37712776 × 10⁶
⇒ n(16) = 100.530326 x 10⁶
⇒ n(16) = 100,530,326 rats
