Solve w+ 3 = -4. w= -7
Which statement shows the correct justification for the step used to solve the equation?
Add 4 to each side.
Add 3 to each side.
Subtract 4 from each side.
Subtract 3 from each side.

Subtract 3 from each side

In the equation:

Subtracting 3 from both sides of the equation. We have:

Therefore:

The simplest way to do this is by moving 3 to the other side of the equation, where it then changes to -3 due to the equality sign (=). this is what I mean:

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.

i can't solve unless i know what the line is
