Note: I may not be correct on all of them. Some of them were confusing a little bit, so I just wanted to let you know. Please don't come after me in the comments if I am wrong with one of the answers. In reality, you should be doing this. Either way, I hope this helps! Please, please, PLEASE mark brainliest.

Answer: 360minutes
Step-by-step explanation:
Speed = space/time ; time = space/speed
space = 600km
speed: 100km/h
time = 600km/100km/h = 6hours
Since 1hour = 60minutes
6hours = 6x60minutes = 360 minutes

<h2><em>Spymore</em></h2>
Answer:
The answer is <u><em>7</em></u>!
Step-by-step explanation:
(x-4) (x) = 21, x^2 - 4x = 21, x^2 - 4x - 21 = 0, (x - 7) (x + 3) = 0, x = 7 and -3; x can't be negative so the answer is 7!
x = 7 and x - 4 (other side) = 3
Answer:
The inverse function is g(x) =
Step-by-step explanation:
You can find the inverse of any function by switching the g(x) value (or whatever the function value is labelled) and the x value. Then solve for the new g(x) value. The result will be your inverse function.
g(x) = 15x - 10 ---> Switch the g(x) and x
x = 15g(x) - 10 ---> Add 10 to both sides
x + 10 = 15g(x) ----> Divide both sides by 15.
= g(x) ----> Switch the order
g(x) =
And that would be your inverse function.
Answer:
The answer is 17
Step-by-step explanation:
To find the answer, we first have to put the values in for a and b.
√225 + ║2 - 3(1/3)(4)║
√225 + ║2 - 4║
√225 + ║-2║
√225 + 2
15 + 2
17
