Answer:
I believe B is the correct answer ?
Step-by-step explanation:
Since the is a negative sign already there that turns the -3 into just 3 so the equation turns into 3-6 which is -3 so...
3-6<3.5
Answer:
The domain is the interval [5,∞)
Step-by-step explanation:
we have
we know that
The radicand (number under a radical) must be greater than or equal to zero
so
solve for x
Adds 5 both sides
therefore
The domain is the interval [5,∞)
All real numbers greater than or equal to 5
The graph crosses the x axis where g(x) = 0 , so:-
x^2 - 5 = 0
x^2 = 5
x = sqrt5 or -sqrt5
so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)
Answer:
50 minutes
Step-by-step explanation:
Use proportions
=
Solve for x
3x = 150
Divide by 3
x = 50 minutes
