2. A grocery store has advertised a sale on ice cream. Each carton of any flavor of ice cream costs $3.79.
a. If Millie buys one carton of strawberry ice cream and one carton of chocolate ice cream, write an
algebraic expression that represents the total cost of buying the ice cream.
b. Write an equivalent expression for your answer in part (a).
c. Explain how the expressions are equivalent.

6 and 24

step-by-step explanation:

6 x 4 = 24

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

the answer should be a. snail

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
