An internet charges a flat rate of $6.50 for shipping. If x represents the cost of items purchased and y represents the total cost of shipping. What equation represents the relationship between x and y?

Question:

An Internet business charges a flat rate of $6.50 for shipping. If x represents the cost of the items purchased and y represents the total cost with shipping, which equation best represents the relationship between x and y?

y = 6.5 + x represents the relationship between x and y

Solution:

Given that,

An internet charges a flat rate of $6.50 for shipping

Let "x" be the cost of items purchased

Let "y" be the total cost with shipping

Therefore,

Total cost with shipping = flat rate of 6.50 + cost of items purchased

Thus, we get,

y = 6.50 + x

y = 6.5 + x

Thus the above equation represents the relationship between x and y

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
