Find the domain and range of the exponential<span> function </span>h<span>(x) = </span>125x<span>. Explain your findings. As x decreases, does </span>h<span> increase or decrease?</span>
Using the given linear function, we have that:
- After 20 hours, 1326 acres will be left to mow.
- After 100 hours, 1230 acres will be left to mow.
- It will take 1125 hours to mow all the lawns.
<h3>What is the linear function?</h3>
The linear function for the number of acres left to mow after x hours is given as follows:
y = 1350 - 1.2x.
After 20 hours, the number acres is given as follows:
y = 1350 - 1.2(20) = 1326.
After 100 hours, the number acres is given as follows:
y = 1350 - 1.2(100) = 1230.
The time it takes to mow all the lawns is given by:
1350 - 1.2x = 0.
1.2x = 1350
x = 1350/1.2
x = 1125 hours

Answer:There you go X is the middle, a only brother, b only sister.
a X =11
b X =9
a b X =14 (20-6)
a b 2x=20
X=6
So 6 in the middle, 6 on the outside, 5 only brothers, 3 only sisters. let me know if I missed anything but we have a total of 20, 6 with none, 11 with brothers and 9 with sisters
