Answer:
Minnie and Amanda have the same amount of posters.
Step-by-step explanation:
Add 16 and 25 posters and Minnie will have a total of 41 posters.
Add 25 and 16 posters and Amanda will have a total of 41 posters.
Each have the same amount of posters regardless if they are new or old.
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
Answer:
If x = 3y and 3y = x, then y = 1/3x.
