Answer:
see below
Step-by-step explanation:
Package A
2n + 3m = 280
Package B
2n + 5m = 320
Using elimination to eliminate n since the coefficient is the same
Subtracting the A equation from the B equation
2n + 5m = 320
-2n - 3m = -280
------------------------
2m = 40
Divide by 2
2m/2 = 40/2
m = 20
Now finding n
2n+3m = 280
2n +3(20) = 280
2n+60 = 280
Subtract 60 from each side
2n +60-60= 280-60
2n = 220
Divide by 2
2n/2 = 220/2
n = 110
The cost per night is 110 and the cost per meal is 20
Answer:
4 Minutes. (Approx, to the nearest minute)
Step-by-step explanation:
24.2% of 680 is: 164.56
164.56 * 4(Minutes) = 658.24
164.56 * 5(Minutes) = 822.8
So since it's rounded up, 5 minutes is too long because it would be long gone by then, and the next highest amount of minutes that it can decay for but not reach LESS than 10 grams left, is 4 minutes.
Answer: My answer to the 1st one would be x=15/2 and the 2nd one -12/5
All of these functions start from the same function, f(x) = x^2, which has an axis of symmetry of x = 0, but they have all been shifted horizontally and vertically.
The first function has been shifted 1 unit to the right and 2 units up, having an axis of symmetry at x = 1.
The second function has been shifted 1 unit to the left and 2 units down, having an axis of symmetry at x = -1.
The third function has been shifted 2 units to the right and 1 unit down, having an axis of symmetry at x = 2.
<span>The fourth function has been shifted 2 units to the left and 1 unit down, having an axis of symmetry at x = -2.
As you can see, because the last function has been shifted 2 units to the left, its axis of symmetry is at x = -2.
Final Answer:
The fourth function, f(x) = (x+2)^2-1 has an axis of symmetry of x = -2.
