Answer:
The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60

Step-by-step explanation:
Answer:
3x^2-6x+3=0
x^2-2x+1=0
x^2-x-x+1=0
x(x-1)-(x-1)=0
(x-1)(x-1)=0
x=1,1
so x has only one answer
so it intersects only one time
