3x(x+8)=0
x=0,-8
This is how to solve for x. Comment if you need something else.
No not all diagonal lines are lines of symmetry! Because if you take a piece of notebook paper and fold it in half the side do not match up! hope this helps :)

Answer:

Step-by-step explanation:
Given
Variation: Directly Proportional
Insects = 10 million when Rate = 2 million
i.e.
when 
Required
Determine the differential equation for the scenario
The variation can be represented as:

Which means that the rate at which the insects increase with time is directly proportional to the number of insects
Convert to equation


Substitute values for
and P

Make k the subject



Substitute
for k in 


A). Remember the equation y=mx+b. The b is the y intercept, and the m is the slope. Plus, if you look at the equation, a) is the only one with - 3/4 in it
