Answer:
b) 
Step-by-step explanation:
We can use the discriminant 
to determine how many real solutions a quadratic equation in the form 
has.
- discriminant > 0 ⇒ 2 real solutions
- discriminant = 0 ⇒ 1 real solution
- discriminant < 0 ⇒ no real solutions

Answer:
m= rise/ run
Step-by-step explanation:
We can find the slope by
m= rise/ run
= change in y/ change in x
= ( y2-y1)/(x2-x1)
= vertical change/ horizontal change
Answer:
27 cubic feet
Step-by-step explanation:
A pyramid is always 1/3 of a cube when it has the same base as a pyramid.
ALSO, thats why the volume of a square pyramid has 1/3 in it.
So, if the volume of this pyramid is 9 cubic feet then:
9 x 3 = 27 cubic feet
Hope this helps!
To factor the given function, find a term that is divisible by both terms. For this problem, the factor would be 2, since 2x^2 and -18 are both divisible by 2.
2(x^2 - 9)
You could further factor out x^2 - 9 because it is factorable by (x - 3) and (x + 3). Thus, it would be
2(x -3)(x+3)
