Step-by-step explanation:
The graph is shifted 3 units to the right
ok turn 7/5 and 3/5 into a decimal
here let me help you
3/5 = 0.6
7/5 = 1.4
1.4 / 0.6 = 2.3 repeat
then turn it back into a fraction which is 2 3/10
this is how I do it by the way.
To solve this problem you must apply the proccedure shown below:
1. You have that the forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9√t<span> acres per hour. Therefore, you have:
</span>
1600+∫(9√t)dt (from 0 to 16)
2. Then, when you solve it, you obtain:
1600+6t^3/2=1984
3. Therefore, as you can see, the answer is: 1984 acres.

[Explanation]
4(x + 6) + 4(x - 5)
[Expand] 4(x + 6): 4x + 24
4x + 24 + 4(x - 5)
[Expand] 4(x - 5): 4x - 20
4x + 24 + 4x + 20
[Simplify] 4x + 24 + 4x - 20: 8x + 4
= 8x + 4
