well from me studing this question i have found the My KeY bOaRd JuSt BrOkE
Answer:
Use the distributive property to multiply 3 by x−2.
y=(3x−6)(x+1)(x−4)
Use the distributive property to multiply 3x−6 by x+1 and combine like terms. y=(3x 2 −3x−6)(x−4)
Use the distributive property to multiply 3x 2
−3x−6 by x−4 and combine like terms.
y =3x 3
−15x 2 +6x+24

I also up a link there of a graph. Please tell me if you can open it. Hope this helps! :P
Answer:
-4x=7
3x+5y=9
Step-by-step explanation:
First setup the system of equations for the given case.
Let sandwich=x
and delivery fee =y
Equations are:
4x+y=33 Equation 1
8x+y=61 Equation 2
Subtract equation 1 from 2.
4x=28
x=7
Now substitute value of x in equation 1.
4(7)+y=33
28+y=33
y=5
So cost of single sandwich=$7 and Delivery fee=$5
Now cost of 12 sandwiches:
12x+y=85
Put y=5
12x+5=85
12x=80
x=6.67 which is less than 7. So, They are not able to get 12 sandwiches for $85.
