A)
D = 0, the equation has 1 real solution
B)
D > 0, the equation has 2 real solutions
C)
As the equation has 2 conjugate imaginary solutions
D)
the nu ber and nature of the solutions cannot be determined

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

yes, whats the problem?
