Y = 4x/3+19/3 move all terms that dont contain to y to the right then solve
Answer:
x -5
Step-by-step explanation:
f(x)= 2x+5, g(x)=x+10,
f-g (x) = 2x+5 - (x+10)
Distribute the minus sign
= 2x+5 - x-10
=2x-x +5-10
Combine like terms
x -5
Answer:
P=400
Step-by-step explanation:
0.8P=320
P=320/0.8
P=400
I assume the task is to simplify.
Answer:
<span>Don't forget S is measured in thousands of units so you are solving for :
100 < 74.5 + 43.75Sin(πt/6)
25.5 < 43.75Sin(πt/6)
Sin(πt/6) >25.5/43.75 = 0.582857
ASrcSin(πt/6) > 0.62224 radians
πt/6 > 0.62224
t > 6 x 0.62224/π = 1.1884 (4dp)
This initial value occurs when the sine value is increasing and it will reach its maximum value of 1 when Sin(πt/6) = Sinπ/2, that is when t = 3.
Consequently, monthly sales exceed 100,000 during the period between t = 1.1884 and 4.8116
[3 - 1.1884 = 1.8116 so the other extreme occurs at 3 + 1.8116]
Note : on the basis of these calculations, January is 0 ≤ t < 1 : February is 1 ≤ t < 2 :....May is 4 ≤ t < 5
So the period when sales exceed 100,000 occurs between Feb 6 and May 25 and annually thereafter.</span>
