Answer:
Ronald
Step-by-step explanation:
RONALD:
Cups of sugar = 2
Cups of flour = 5
Cups of sugar / cup of flour mixed = 2/5 = 0.4 per cup
MADELYN :
Cups of sugar = 6
Cups of flour = 16
Amount of sugar per cup of flour :
Cups of sugar / cup of flour mixed = 6/16 = 0.375 per cup
RONALD'S cake is sweeter, it has greater amount of sugar per cup than madelyn's
For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
