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: 10
Step-by-step explanation:
Hope this helps!
Answer:
yes
Step-by-step explanation:
because -8+3=-5, and -8-(-3) has to cancel out the 2 negatives which will change it to -8+3 which makes it the same question
4.293
=4+(293/1000)
=(4000/1000)+(293/1000)
=4293/1000
The answer is actually 37/36, or 1 1/36. The error was that when Mario multiplied 9 by 4, he only added the 4 to 4 instead of multiplying 4 by 4. <span />
