PLS PLS PLS HELP True or false: 6x² - 4y - 3x + 6x² + 8x= 12x² + 5x - 4y

True

Step-by-step explanation:

6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y

Regroup terms on left

6x² + 6x² - 3x + 8x - 4y = 12x² + 5x - 4y

Combine like terms

on left

12x² + 5x - 4y = 12x² + 5x - 4y     True

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.
