The height h (t) above ground (in yards) of a helium- filled balloon t seconds after release is shown in the
table.
What is the average rate of change of the balloon from
t = 7 seconds to t = 15 seconds?
a) 0.8 yd/sec
b) 1.25 yd/sec
c) 1.59 yd/sec
d)2.14 yd/sec

The graph below shows the price of different numbers of mats at a store: a graph is shown. the values on the x axis are 0, 2, 4, 6, 8, 10. the values on the y axis are 0, 21, 42, 63, 84, and 105. points are shown on ordered pairs 0, 0 and 2, 21 and 4, 42 and 6, 63 and 8, 84. these points are connected by a line. the label on the x axis is number of mats. the title on the y axis is price in dollars. which equation can be used to determine p, the cost of b mats?

100 points, hi, i’m not sure how to get the equation from the graph and table.

Which one is true about the hexagons ?
