Answer:
i am pretty sure it is A/the graph is a straight line that has a slope of 6
Step-by-step explanation:
A)
A polygon is a closed shape so there must be at least three sides. Therefore, the least value that n can be would be three.
b)

Answer:
y= -1x+ 7
Step-by-step explanation:
x in a equation is slope and the other number is y- intercept
Answer:
c
Step-by-step explanation:
Let's call:
f = price of 1 cup of dried fruit
a = price of 1 cup of almonds
In order to build the linear system, you need to consider that the total price of a bag is given by the sum of the price of cups times the number of cups in each bag, therefore:

Solve for a in first equation:
a = (6 - 3f) / 4
Then substitute in the second equation:
41/2 f + 6 · (6 - 3f) / <span>4 = 9
41/2 f + 9 - 9/2 f = 9
16 f = 0
f = 0
Now, substitute this value in the formula found for a:
</span>a = (6 - 3·0) / <span>4
= 3/2 = 1.5
Hence, the cups of dried fruit are free and 1 cup of almond costs 1.5$</span>
