Which section holds the solution to the system?
y > 2x + 5 y < -1x
Area 3
It has both shading (green & orange) because it is holds solutions to BOTH inequalities

The local pond had 12 frogs in April and the frog population doubled every month!
How many frogs would there be in December?
F(m) = 12(2)^x
F(8) = 12(2)^8
F(8) = 3072

What rule takes effect when we multiply or divide with a negative in inequalities?
-5x > 10
Me must flip the inequality symbol
because negative values work the OPPOSITE that positives values work.

The perimeter is equivalent to 5x + 8. Write an equation to solve for x.
x^2+5x+4=5x+8
x^2-4=0
(x+2)(x-2)=0
x=-2 x=2
