Answer:
12.5
Step-by-step explanation:
In order to solve, we need to add 9 to both sides of the equation:
<u>Our sum applied:</u>
b=12.5
Answer:
Y=77/x
Explanation:
Y varies inversely with x meaning
adding a proportionality constant gives
Now, we are told that y = 11 and x = 7; therefore, the above gives
Solving for k gives
Therefore, the function that models the inverse variation is
which is our answer!
Answer:
Step-by-step explanation:
c(t)=40:0≤t≤400
=40+0.50 (t-400):t≥400
3/8 = 0,375
5/12 = 0,416
5/12 is bigger
