Step-by-step explanation:
A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution. A negative discriminant indicates that neither of the solutions are real numbers.

</h2>
Step-by-step explanation:
We have,
To find, the product of the rational expressions = ?
∴
= 
= 
= 
=
Thus, the product of the rational expressions =
C because it is to the nearest tenth I think
Answer:
Answer is first line
Step-by-step explanation:
-7(x+9) >= 37+3x
Going to solve for x:
-7x - 63 >= 37 + 3x
-7x - 3x >= 37 + 63
-10x >= 100
x <= 100/-10 (notice the change in equality because we divided by negative)
x <= -10
15a =6a - 90
Move all the numbers with variables to one side
15a - (6a) = 6a -(6a) -90
9a = -90
9a/9 = -90/9
a = -9
Hope this helps
