Answer:

k = 220

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 22 when x = 10

k = yx = 22 × 10 = 220

Identify the type of function represented by each graph

mario62 [17]

Answer:

13. Linear Function

12. Absolute Value Function

11. Quadratic Function

10. Constant and Linear Function

Step-by-step explanation:

13. This graph is in Slope-Intercept Form, $y = mx + b$ . The equation of this line is $y = x + 1$ .

12. This graph obviously is an Absolute Value graph because it is in the shape of a "V".

11. This graph is in the shape of a parabola, so it is considered "Quadratic".

10. This line is constant because it is a horizontal line, but it is ALSO considered a linear function because it is in the form of $y = mx + b$ , and the equation of this line is $y = -2$ , where you have NO rate of change [slope]. This is what you call horizontal lines, zero slopes.
