The expression for the total cost of their trip is 7 + 2x + 3y.
As per the question, assuming the number of bottles to be x and number of bags to be y. The equation will have one time fee of admission, product of cost of bottles and number of bottles and product of cost of bags and number of chips bags.
The one time fee and two products will be added to form the expression. Forming the equation now -
Expression = 7 + 2x + 3y
Therefore, the expression of trip when x bottles of water were bought during the visit is 7 + 2x + 3y.

Answer:

Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line

Let's simplify the equation of the line to get:


The slope of this line is -5.
The perpendicular to this line has a slope of

The equation going through (6,-10) is

We substitute to get;

Expand;


Answer:
The relationship is linear: y -5 = 2 (x+7)
Step-by-step explanation:
While the difference between -7 and -5 / -5 and -3 / -3 and -1 is always 2 teh difference between 5 and 9 / 9 and 13 / 13 and 17 is always 4.
y-5 = -1/2 (x +7)
for x= -7 and y = 5 this is true
for x=-5 and y = 9 this is not true
y + 7 = 1/2 (x-5)
for x= -7 and y = 5 this is not true
y -5 = 2 (x+7)
for x= -7 and y = 5 this is true
for x = -5 and y = 9 this is true
for x = -3 and y = 13 this is true
for x = -1 and y = 17 this is true
