Answer:
6x
Step-by-step explanation:
3x/y=x/2y
Since 2y is 2X greater than y, 6x is 2X greater than 3x.
So,
The answer is 6x.
To the nearest thousand, because when you are estimating numbers, you always round to the nearest higher place (like the nearest tenth if comparing 26 and 18).
3x^(2)+4x-3x-5-2=0
3x^(2)+x-7=0
Discriminat= b^(2)-4ac= 1^(2)-4(3)(-7)= 1-12(-7)=1+84=85
The discrimination is bigger than 0 (delta>0) therefore there are 2 real solutions
Answer:
Roots are complex numbers
Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If -----> The equation has only one real root
If -----> The equation has two real roots
If -----> The equation has complex roots
In this problem the discriminant is -8
so
-8 < 0
therefore
Roots are complex numbers
