Explanation:</h2>
The complete question is in a comment above. The statements says that:
- Sean wrote the equation
is the cost per pound.- The equation show the relationships between the total cost, $9.25, and the number of pounds of pears.
So we are asked to write an write an equation to show the cost y of x pounds of pears. In other words, we need to write an equation such that y is given in terms of x, where x is the pounds of pears. So:
From the equation we can determine as:
So each pound costs $1.85. The equation tells us that 5 pounds of pears result costs $9.25. Then, by proportion:
So choosing the number of pounds as 0, 1, 2, 3, 4, 5, the table would be:
From the table we can know that the graph is a line. that passes through all these points. Since this line passes through the origin, then y varies directly as x (Direct Proportion).

Answer:
Step-by-step explanation:
We have been given that searches related in 1997 there were 43.2 who used free weights increases 6% annually. We are asked to write an equation for the number of people using free weights t year after 1997.
Let 
represent year 1997.
We will use exponential growth formula to write our given function.
, where,
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
x = time.
Let us convert 6% into decimal form.
Initially there were 43.2 who used free weights, so initial value is 43.2.
Upon substituting our given values in exponential growth formula, we will get:
Therefore, our required equation would be .
Answer:
<h3>
Assuming A, B, and C are collinear and B is between A and C then x = -2
2</h3>
Step-by-step explanation:
Assuming A, B, and C are collinear and B is beetween A and C
AB + BC = AC
48 + 2x + 139 = x + 165
2x + 187 = x + 165
x = -22
