Aproportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (5, 4) is on the graphed line.

part a: what is the price of 1 pound of potatoes? show your work, including the proportion you used to determine the price.
part b: what does the ordered pair (10, 8) on the graph represent? explain in words.

(5, 4) = (x, y)

to get the unit rate we need to divide/simplify the relationship:

4 ÷ 5 = 0.8

1 pound of potatoes cost 0.8$

1 potato = .80  

10 potatoes cost 8$

Step-by-step explanation:

4 ÷ 5 = 0.8 0.8 = .80$

so one potato costs .80$

80 x 10 = 8 0

i have no clue at all sorry

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
