Amber should’ve added -3 and 5 first instead of adding 5 and 4.
Answer:
$205.35
Step-by-step explanation:
First, divide 38.85 by 7. You should get 5.55 for every 1 hour.
Then, multiply 5.55 by 37. You should get 205.35
So for 37 hours, Jim will earn 205.35
Hope this helped!

Answer:
Period=6
Step-by-step explanation:
Given:
t=1cos(1.05h)+37
Using acos(bx-c)+d to find the period of the given function
amplitude= a
period= 2π/Bb
phase shift=c (positive is to the left)
vertical shift=d
comparing with t=1cos(1.05h)+37, we get
a=1
b=1.05
c=0
d=37
period= 2π/b
=2π/1.05
=5.983
=6
Period of function is 6, after every 6 hours the refrigerator sensor will reach its maximum temperature and the cycle will move towards reducing temperature i.e it'll reach the minimum temperature then again the cycle will move upwards raising the temperature to maximum and so one period will be completed!
Answer:
x = 3 - 3/2y
y = 2 - 2/3x
Step-by-step explanation:
2x + 3y = 6
2x = 6 - 3y
x = 3 - 3/2y
2x + 3y = 6
3y = 6 - 2x
y = 2 - 2/3x
