= cos(x-π/2)/sin(x-π/2)
= (cos(x)cos(π/2) + sin((x)sin(π/2)) / (sin(x)cos(π/2) - cos(x)sin(π/2)
= sin(x)/ (-cos(x)) .... cos(π/2) = 0; sin(π/2) = 1
= -tan(x)
idk if this is right but i tried
Let's solve ~
Assume width of rectangle be " x ", length = 3×width + 8 = 3x + 8 ~
Now, Perimeter of rectangle is :
Hence, width = x = 5 cm
And, length = 26 cm
The equation that shows the relationship between the number of round trips, x and the number of kilometers, y Scott walked is y = 3x
Each round trip = 3 km
x = number of rounds
y = number of km he has walked in all.
1 rounds = 3 km
Therefore,
x rounds = 3x km
Each round of trip covers 3km. This means for each round of trip a distance of 3km is covered. The total distance or number of kilometers is represented with y.
The equation to show the relationship between x(number of rounds) and y (number of km) can be represented below
