and a 0 slope is a line parallel to the x axis
The answer is 12+3r because 4 times 3=12 then the 3r which you cannot add because they are no others variables that are r
Answer:
Takin LHS
cot²a . cos²a
cos²a/sin²a-cos²a
cos²a -cos²a.sin²a/sin²a
cos²a(1-sin²a)/sin²a
cot²a.cos²a LSH=RHS PROved

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 9(3)ˣ
x = -1
<u>Step 2: Solve</u>
- Substitute: f(-1) = 9(3)⁻¹
- Evaluate: f(-1) = 9(1/3)
- Multiply: f(-1) = 9/3
- Divide: f(-1) = 3
