hat is the value of the discriminant for the quadratic equation 0 = x + 2 + x2? Discriminant = b2 – 4ac –9 –7 7 9
2 answers:
For the general quadratic equation ax^2 + bx + c = 0 the discriminant is b^2 - 4ac.
So, for x^2 + x + 2 = 0, a = 1, b = 1, and c = 2, therefore
b^2 - 4ac = 1^2 - 4(1)(2) = 1 - 8 = - 7.
Answer: - 7
Answer:
(B)-7

Answer:
C.60
Step-by-step explanation:
4×12=48
18-12=6
6×2=12
48+12=60
I think the first one is 4x=3
3). y = -1/3x + 5
4). y = -1x +5
Slope intercept form: y = mx + b
m = slope
b = y intercept
