First, replace f(x) with y . ...
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y . ...
Replace y with f−1(x) f − 1 ( x ) . ...
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Answer:
The answer is a 2
Step-by-step explanation:
Is a 2 because the point 1 is a 2 line
Answer:
it would be 5%
Step-by-step explanation:
10%÷2=0.05%
check the picture below.
recall that the sum of all interior angles in a triangle is 180°, and that a flat-line like the line C, D and E are sitting on, is always 180°.
X = width
2x - 3 = length
2w + 2l = perimeter
2(x) + 2(2x - 3) = 210
2x + 4x - 6 = 210
6x - 6 = 210
6x = 216
x = 36
2(36) - 3 = y
72 - 3 = y
69 = y
width = 36 cm
length = 69 cm
