Answer:
b=-3
Step-by-step explanation:
This is simple, its obviously 420ohms c:
if the equation is y+=1/2 (x-3) the slope is wrong. the slope is actually 6. that was the error that Sydney made. i hope this help some of my people out:)
Step-by-step explanation:
now you got this go kill that essay:))))
Step-by-step explanation:
Plot the four zeroes as points on the x-axis (y = 0) then draw a positive quartic curve.
Answer:
Since b^2 -4ac = -31 we have 2 complex roots
Step-by-step explanation:
2x^2+ 5x+7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =2 b=5 and c=7
(5)^2 - 4(2)(7)
25 - 56
-31
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = -31 we have 2 complex roots
