Answer:
d.) 81
Step-by-step explanation:
f(2) would be 27 and 27x3 is 81.
81/3=27
27/3=9
Answer:
Its either A or C
Step-by-step explanation: times the 45.00 x 0.15 and then try 45.00 x 1.14 it will give you the answer :D
<h3>Slopes of perpendicular lines.</h3>
Let k: y = a₁x + b₁ and l: y = a₂x + b₂. Then
<h3>k ║ l ⇔ a₁ = a₂</h3><h3>k ⊥ l ⇔ a₁ · a₂ = -1</h3>
We have the line y = -x + 5 ⇒ a₁ = -1.
Therefore
a₂ · (-1) = -1
-a₂ = -1 I<em>change the signs</em>
<h2>a₂ = 1</h2>
