Answer:
D = 120, there are 2 real roots for F(x)
Step-by-step explanatU
using the
formula D = b^2 - 4ac for discriminant
D = 8^2 - 4*(-7)*2
D = 64 + 56 = 120
Answer:
66/125
Step-by-step explanation:
Divide top ad bottom by 8. The resulting fraction cannot be simplified further.
-6,0
i hope this helps and the y intercept is
0,8
Answer:
Slope: m = 0
Equation: y = 3
Step-by-step explanation:
The equation of a line has the following format:

In which m is the slope.
We choose two points which the equation crosses.
I am going to choose (0,3) and (1,3)
(0,3)
When x = 0, y = 3. So



(1,3)
When x = 1, y = 3. So



Slope: m = 0
Equation: y = 3
115% of the price is 270,25
115*x/100=270,25
x=270,25*100/115
x=235 $ is the price
270,25-235= 35,25 $ is the tax
