The function g(n)=n²-6n+16 represents a parabola.

goblinko [34]

Part A: (n^2-6n)+16

[(n^2-6n+9)-9]+16

(n-3)^2+7

Part B: From the above result,

Vertex (3,7) this is the minimum point of the graph since the coefficient of a is positive

Part C: The axis of symmetry is basically the x coordinate of the vertex, so the axis of symmetry is x=3

Answer:

7. 15.5

8. 12

Step-by-step explanation:

Question 7 equation: $\frac{3*1}{2} + \frac{5+2}{2} * 4=1.5 + 3.5 * 4 = 1.5 + 14 = 15.5$ .

Question 8 equation: $(\frac{2*2}{2} * 2) + (\frac{4*2}{2} *2) = 4 + 8 = 12.$

Katerina saves her quarters and dimes. She plans to exchange the quarters for paper money when the total value equals $10. Use t

Lena [83]

Since you can only obtain exactly $10 if you have an even amount of quarters you will need to plot 2x + y. With 'x' being the quarters and 'y' being the dimes.
