What equation is equivalent to 2+3(2x+4)=13

14+6x=13, or further 1+6x=0

Step-by-step explanation:

2+3(2x+4)=13,

Distribute the 3 into the parenthesis:

2+6x+12=13

Now combine like terms: 14+6x=13.

You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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.
