Answer: + or - (square root of 3)/2
Step-by-step explanation:
3-4x^2=0
Add 4x^2 on both sides
3-4x^2+4x^2=0+4x^2
3=4x^2
Divide both sides by 4
4x^2/4 = 3/4
x^2 = 3/4
Since it’s a square x can be a negative number or a positive number.
x = square root (3/4) = (square root of 3)/2
x = + or - (square root of 3)/2
So, first you subtract 10 from 38 which gives three times of the money spent for the movie. Then you divide 3 from it to give you the answer.
38-10 = 28
28/3 = 9.37 dollars
Move all terms that don't contain y to the right side and solve y=3x+4
