1x + 8 = 10 + 0.5x
1x - 0.5x = .5x
.5x + 8 = 10
10 - 8 = 2
2/.5 = 4
Therefore, it will take 4 years for the two trees to have grown to the same height.
Answer:
1/3,1/4,and so on like increasing in number
We need to find the 8 th term nth term is given as <span><span>an</span>=<span>a1</span>+(n−1)d</span>
n=8, d =-4 (common difference) <span><span>a8</span>=<span>a1</span>+(8−1)×d</span>
<span><span>a8</span>=1+7×(−4<span>)</span></span>
The center is (-2,0)
The radius is -3
