PLEASE ANSWER QUICK (02.03 MC)
Figure EFGH on the grid below represents a trapezoidal plate at its
starting position on a rotating surface:
The plate is rotated 90° about the origin in the counterclockwise
direction. In the rotated trapezoid, what are the coordinates of the
endpoints of the side congruent to side EH?

answers-
(8,4) and (5,2)
(4,-8) and (2,-5)
(-8,-4) and (-5,-2)
(-8,-4) and (-5,-7)

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.

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

the correct answer is $7.38
