15% of 45 is 0.15 x 45 or 6.75 feet. That's how far the submarine descended in 1 minute. So, in 4 minutes the submarine would be 4 x 6.75 feet down which is 27 feet.
Hi there!
• g(x) = 6x - 3
Then,
if g(x) = y :-
y = 6x - 3
⇒6x = y + 3
⇒x =
According to th' question :-
g⁻¹(x) =
g⁻¹(9) =
g⁻¹(9) =
g⁻¹(9) = 2
Hence,
The required answer is g⁻¹(9) = 2
~ Hope it helps!
Answer:
20
Step-by-step explanation:
x-2y=6 and x+y=10
Multiply the second equation by 2
2x+2y = 20
