Step-by-step explanation:
(8y + 5) - 2z
y = 3, z = 9
Let's plug in the given values.
(8(3) + 5) - 2(9)
First let's multiply.
(24 + 5) - 18
Now simplify within the parentheses.
29 - 18
Subtract.
11
This is your answer.
Hope this helps!

Answer:
cot . (x- π/2)= - tanx
Step-by-step explanation:
cot . (x- π/2)= - tanx
cot .x - cot π/2= - tanx
cot π/2= 1/tanπ/2
But tan π/2= ∞
cot π/2 = 1/∞= 0
cotx - 0= - tanx
cot x = - tanx
cosx/sinx= - sinx/cosx Putting values of cot and tan
cosx/ sinx ( sinx/cos x) = -sinx/cos x (sinx/cos x )
Multiplying both sides with sinx/cos x
1= - sin²x/cos²x
cos²x= - sin²x as cosx = -sinx
