Step-by-step explanation:
Given: (a+b)²
To prove: (a+b)² = a² + 2ab + b²
Proof:-
(a+b)² = (a+b)(a+b)
(a+b)²=a(a+b)+b(a+b)
(a+b)² = a²+ab+ab+b²
(a+b)² = a²+2ab+b².
Answer:
The inverse is 1/2x +3
Step-by-step explanation:
f(x) = 2x-6
y = 2x-6
Exchange x and y
x =2y-6
Solve for y
x+6 =2y
Divide by 2
1/2x +3 = y
The inverse is 1/2x +3
The distance is 5. Hope this helps!
