Find the coordinates of the vertices of each figure after the given transformation.
7) rotation 180 degrees about the origin
z(-1,-5) ,k(-1,0) c(1,1) m (3,-2)

Z'(1, 5), K'(1, 0), C'(−1, −1), M'(−3, 2)

Step-by-step explanation:

According to the 180°-rotation rule, you take the OPPOSITE of both the x-coordinate and y-coordinate:

180°: [x, y] → [−x, −y]

Z(−1, −5) → Z'(1, 5)

K(−1, 0) → K'(1, 0)

C(1, 1) → C'(−1, −1)

M(3, −2) → M'(−3, 2)

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.

the equivalent expression are always the hardest ones but you look at the gcf also
