Three lemon creams +2 fudge cookies have 400 cal. two lemon creams +3 fudge cookies have 425 cal. how many calories are in each kind of cookie?

lemon 70. Fudge 95

Step-by-step explanation:

3L + 2F=400

2L + 3F = 425

Multiply to get inverse additives.

2( 3L + 2F)= 2(400)

-3(2L + 3F) = -3(425)

6L + 4F = 800

-6L + (-9F) = -1275

6Ls cancel out

4F-9F=-475

-5F=-475

Divide by -5

F=95

Go back and put 95 in for F.

3L + 2 (95)=400

3L+190=400

Subtract 190 from each side

3L=210.

Divide by 3.

L=70

answer: the answer is 127 degrees

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
