A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 2. The second column is labeled f (x) with entries 18, 6, 2, two-thirds.
What is the decay factor of the exponential function represented by the table?

One-third
Two-thirds
2
6

1/3 (one-third)

Step-by-step explanation:

Pay attention to the column of f(x), as those are the coordinates that are decreasing exponentially. To find the decay factor, figure out the number that each value is being multiplied by to get to the next value.

18(1/3) = 6

6(1/3) = 2

2(1/3) = 2/3 (two-thirds)

Therefore, the decay factor is 1/3 (one-third).

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
