Answer:

See below

Step-by-step explanation:

11x^2 + x^2 = (4x + 8)(3x - 3)
12x^2 = 12x^2 + 24x - 12x - 24
12x - 24 = 0
12x = 24
x = 2

x/3 - x/9 = 6
3x/9 - x/9 = 6
2x/9 = 6
2x = 54
x = 27

6^(x + 9) = 36^x
6^(x + 9) = 6^(2x)
x + 9 = 2x
2x - x = 9
x = 9

4/9 + 1/a = 2/3
1/a = 2/3 - 4/9
1/a = 6/9 - 4/9
1/a = 2/9
a = 9/2

√x + 3 = 6
x + 3 = 6^2
x = 36 - 3
x = 33

1.2m - 0.2 = 3.8 + m

1.2m - m = 3.8 + 0.2
0.2m = 4
m = 4/0.2
m = 20

(x + 12)^2 = 9
x + 12 = ± 3
x = ± 3 - 12
x = - 9, x = - 15

Answer:

See attached graph for the first part

Answer to second part: The end part of the graph show the slowest increase

Step-by-step explanation:

The attached picture represents the number of infected people, starting with a relatively small number at the origin of the horizontal axis (x=0, or time=0) then increasing abruptly in the center of the graph with steep slope. and then infection slowing down (although still slowly increasing) in the region highlighted in yellow to the right of the graph.
