The equation that models the number of students who live in apartments will be 6n + 15
<h3>How to illustrate the equation?</h3>
Total number of students T = 17n + 23
Students who live in dorm rooms on campus D = 11n + 8.
Therefore, the students who live in apartments will be:
= 17n + 23 - (11n + 8)
= 6n + 15
In order to predict the number of students who will live on campus in 2020, we will need the students that do not share dorm rooms.

Answer:
<h2>14mph</h2>
Step-by-step explanation:
Given the gas mileage for a certain vehicle modeled by the equation m=−0.05x²+3.5x−49 where x is the speed of the vehicle in mph. In order to determine the speed(s) at which the car gets 9 mpg, we will substitute the value of m = 9 into the modeled equation and calculate x as shown;
m = −0.05x²+3.5x−49
when m= 9
9 = −0.05x²+3.5x−49
−0.05x²+3.5x−49 = 9
0.05x²-3.5x+49 = -9
Multiplying through by 100
5x²+350x−4900 = 900
Dividing through by 5;
x²+70x−980 = 180
x²+70x−980 - 180 = 0
x²+70x−1160 = 0
Using the general formula to get x;
a = 1, b = 70, c = -1160
x = -70±√70²-4(1)(-1160)/2
x = -70±√4900+4640)/2
x = -70±(√4900+4640)/2
x = -70±√9540/2
x = -70±97.7/2
x = -70+97.7/2
x = 27.7/2
x = 13.85mph
x ≈ 14 mph
Hence, the speed(s) at which the car gets 9 mpg to the nearest mph is 14mph

Answer:
120
equation: 40+8(10)=120
Step-by-step explanation:
The math for this is $40 initial plus $8x the 10 weeks which equals 80 so
40+80=120
