Question
what is -7b + 5b + 3b =
Answer:
<h2>
b</h2>
Step-by-step explanation:
-7b + 5b + 3b =
-2b + 3b =
b
2/3x +12/3 =7
2/3x + 4 =7
2/3x=7-4
2/3x=3
x=3*3/2
x=3
10y + 70= 12y
12y-10y=70
2y=70
y=70/2=35
The discriminant explains how many solutions the quadratic function has. It is found using this formula:

Using the formula, there are three rules. Let's say the discriminant=d:
d<0 - No solution ø
d=0 -ONLY 1 solution
d>0 -2 solutions
In the following graph, there are no solutions as the graph does not hit the x-axis at any point.
Thereafter, the discriminant MUST be less than zero. Let's view the options check which one agrees with our answer.
A - Discriminant is greater than 0, which means two solutions. This is WRONG.
B - Discriminant is less than 0, which means no solutions. CORRECT!C- Discriminant is equal to 0, which means one solution. WRONG!
Your answer is B.
This problem is far beyond my capability this problem is declared to be one of the toughest in the world due to it not agreeing with the quadratic formula
