13+x greater than or equal to 20
Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis
Answer: C final income
Step-by-step explanation: I might be wrong but im pretty sure that its C.
Good Luck!
None
the slope of the suggested lines is either 1 or -1
and none of the equal to the slope of the red line in the graph wichc is 2
