Your basically building a new equation with the two functions given to you.
(sqrt(3x + 7)) + (sqrt(3x - 7)) = 0
Then just open up the brackets and simplify further.
sqrt(3x + 7) + sqrt(3x - 7)= 0
Nothing to special really happened there, just removed the brackets. Now you move one of the radicals to the other side so you can square the whole equation.
sqrt(3x + 7) = - sqrt(3x - 7)
Then go ahead and square both sides to remove the radical.
3x + 7 = 3x - 7
Now if you kept trying to isolate x, you find that both sides will just cancel each other out and you are left with,
7 = -7
Since that statement isn't true your answer will be that there is no solution to this equation.
x ∈ Ø
Answer:
55.5 seconds
Step-by-step explanation:
The distance between the deer and bear is increasing at the rate of ...
(7 ft/s) +(3 ft/s) = 10 ft/s
The total distance apart we're interested in is ...
(185 yd)(3 ft/yd) = 555 ft
The time required to make a gap that large is ...
time = distance/speed = (555 ft)/(10 ft/s) = 55.5 s
It will be 55.5 seconds until the animals are 185 yards apart.

I think it would reflect y less than x as we start x^2 for f(x) and usually 1 or 2 is the answer in quadratics. Once we have found y we can work out x
