The question is below

see explanation

Step-by-step explanation:

b = 79° ← corresponding angles are congruent

c = 83° ← vertical angles are congruent

a and b and c and d are same side interior angles and are supplementary, thus

a = 180° - b = 180° - 79° = 101°

d = 180° - c = 180° - 83° = 97°

Thus

a = 101°, b = 79°, c = 83°, d = 97°

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
