Step-by-step explanation:
We have,
If a quadratic equation with real coefficients has a discriminant of -36.
The general form of quadratic equation is :

The discriminant of this equation is : 
If D=0, it will have 1 real roots
If D>0, it will have 2 real roots
If D<0, it will have no real roots
We have,
D = -36 < 0, so, the quadratic equation will have no real roots.
Its the table on the bottom left
For each increase of 1 of x y increases by 0.5 so its linear
I think the equation is
y=-1/3x +10/3
(1/3x+y=10/3)•3
x+3y=10, is the answer
Answer:
1.14
Step-by-step explanation:
Start=12.00
Change= 8.57
Finish= 3.43 ( 12.00-8.57)
Divide finish by 3 3.43/3= 1.14
there will be a remainder of 1 cent unless you wanna be technical it wold be
