Answer: x = -5 and y = -5
Step-by-step explanation:
They drew the linear graph for the simultaneous equations on the graph already
The answer the the equations is the intersection of the lines which is (-5,-5) or x = -5 and y = -5
The given function is

with
t = time, hours
f = temperature, °C
Because the maximum and minimum values for the Sine function are +1 and -1 respectively,
The maximum value of f = 33 - 20 = 13.
The minimum value of f = -33 - 20 = -53.
The period, T, is given by

Answer:
Maximum: 13°; Minimum: -53°; period: 4 hours
Start off by stating your facts. You have a maximum of $8.75. We know that each quarter is 25 cents so we multiply 25x26 equaling 650. Yet we need a decimal so it would be $6.50. Each nickel is worth 5 cents so then you would minus $8.75 and $6.50 getting us to $2.25. Now divide it by 5 cents and you should get 45 nickels. You can also do this by stating that 10 nickels is 50 cents and go until you get 45
$285×15/100
= $42.75 and this is the discount
$285-42.75 = $242.25
Sally will buy the bicycle at $ 242.25
4/500=0.008
