Answer:
2x-2=-4
5/8x3/5= 15/40 then u simplify and get -4 3/8
2
This means for every 1 can of black paint there are 2 cans of white paint in the mix
Step-by-step explanation:
The constant of proportionality is the gradient of line which can be evaluated as follows;
Gradient = delta y / delta x
Gradient = (y2 – y 1) / (x2 – x1)
We shall pick two points on the line graph in (x,y) format;
(3. 6) and (1, 2)
We evaluate the gradient now be repalivn the points on the formula;
Gradient = (2 – 6) / 1 – 3
Gradient = - 4 / - 2
Gradeint = 2/1 = 2
= 2
This means for every 1 can of black paint there are 2 cans of white paint in the mix

<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>
