Answer:
$1315.15
Step-by-step explanation:
x=901 * 0.15
Original price * the discount gives you your original price
You can use substitution and solve y-x=2 for y which is y= x+ 2 and plug it into the y of the other equasion and you get x=5 y=7
The weight of the heaviest fish is 15.2 pounds
•since the average is 13.2, we will multiply 13.2 by 5 because there is 5 total fish. this makes a total of 66 pounds between the 5 fish. then we will subtract the weights of the 4 fish given to us from the total of 66, to get the remaining weight of 15.2 pounds. that also happens to be the heaviest weight, so 15.2 is the correct answer
Answer:
y=120
Step-by-step explanation: 60 x 2 = 120
15x + 120
Try this solution+explanation:
1. the common formula for this graph is y=A*cos(Bx), where A - the amplitude, B - the frequency of the given function.
2. The max. and min. vertical values are 4 and (-4), it means that the amplitude is 4 (A=-4*),
for the function y=cosx the period is 2π, it means for the given function the period is π/2, it is for its frequency 2π/(π/2)=B=4.
* if to see to the suggested graph, the max. of cos4x are in points π/4+πn, and the min. are in π*n/2, it means that it need to add '-' in the equation of the function.
3. answer: y=-4cos4x.
