Amanda enjoys cycling. The graph shows the relationship between the number of hours she rides her bike, x, and the number of miles she covers. The equation that represents the relationship between the number of hours she rides, x, and the distance she covers, y, is a 14y = x
b y=14x c y+14=x d y= 14+x. Using the equation, the distance she would cover if she rode for 1.5 hours would be a 12.5 b 15.5 c 21 d 28 miles.

y is 14x

Step-by-step explanation:

every time she travels 14 miles, she is on her bike for one hour

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

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.
