Answer:

D - No, the ordered pair (4,9) is a solution to this problem.

Step-by-step explanation:

If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)

In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;

(2, 4.5)

(3, 6.75)

(4, 9)

So that is why the ordered pair of (4,9) would be a solution to this problem.

Hope that makes sense!

Sum of interior angles=180(5-2)

Sum of interior angles=180x3

Sum of interior angles=540

Size of each interior angle =540/n

Size of each interior angle =540/5

Size of each interior angle=108

x=108/2

Which statement best compares the graphs of y=-3x^n and y=3x^n?
devlian [24]

Answer:

The graph of y=-3x^n is the reflection of the graph of y=3x^n about the x axis.

Step-by-step explanation:

If you graph these two functions, then you will notice that they look similar. for example the points of (1,-3) on graph y=-3x^n and point (-1,-3) on graph y=3x^n. They have the same y value but just the reflection of the x value. I hope this helped !!
