350 cm^2 (A for connections academy)
Answer:
discriminant=0
Number of real solutions=1
Step-by-step explanation:
Given the equation:
-9x^2-6x-1=0
Let a: coefficient of x^2
Let b: coefficient of x
Let c: constant
a=-9
b=-6
c=-1
The formula of the discriminant is given by:
discriminant= b^2 - 4ac
discriminant= (-6)^2 - 4(-9)(-1)
= 36 - 36 = 0
We know that:
If discriminant<0 then the equation has no real root
If discriminant=0 the equation has one real root
If discriminant>0 the equation has 2 real roots
Here we got discriminant=0 so the quadratic equation has 1 real root.
Answer:
Step-by-step explanation:
Use the slope-intercept form to find the slope and y-intercept
Any line can be graphed using two points.
Select two values, and plug them into the equation to find the corresponding
values.
Graph the line using the slope and the y-intercept, or the points.
Then you are able to substitute in X and it can have a infinite number of values catered to the question.
