Answer:
Step-by-step explanation:
y=x^2+8x+12
y = (x² +8x +16) -16 +12
y = ( x +4)² - 4....standard vertex form
the vertex is : A(- 4 ; - 4)
Ca + g +co = 100 ;
ca*0.50 + g*0.05 + co*1.00 = 15.00 ; / * 20
where ca = numbers of candy bar; g = numbers of gum ball; co = numbers of cotton candy;
We have to combine ca + g + co = 100 with 10ca + g + 20co =300 ;
10ca - ca + g - g +20co - co = 200;
9ca + 19co = 200;
ca = 18; co = 2 and g = 100 - ( 18 + 2 ) = 80.
