What is an equation of the line that passes through the point (-5,3) and is parallel to the line 3x – 5y = 30?

Step-by-step explanation:

3x - 5y = 30

-5y = -3x + 30

5y = 3x - 30

y = 3/5x - 6

y - 3 = 3/5(x + 5)

y - 3 = 3/5x + 3

y = 3/5x + 6

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.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
