Answer:
20 cookies - <u>$ 12</u>
Step-by-step explanation:
6 cookies - $3.60
20 cookies - X
X = (20 · 3,60) : 6
<u>X = $ 12</u>
The "20" under <em>n</em> means "When <em>n</em> is 20,". Therefor, on the other side of the table, 5n-2 would be 5(20)-2. 5*20=100, 100-2 is 98. The top missing value is 98.
For the other side, it's saying that 5n-2 is 38. You have to work backwards to get your answer. The opposite of -2 is 2, so 38 + 2 is 40. The opposite of *5 is /5, so 40/5 is 8. The bottom missing value is 8.
20/q = 7/9
20×9 = 7q
7q = 180
q = 180/7
Reading from the graph, we find the vertex (lowest part of the graph) is at (-0.5, -6.5)
The axis of symmetry is a vertical line (in this case) passing through the vertex, namely x=-0.5
