2c + b = 37 ....multiply by -3
4c + 3b = 81

Select the correct answer.<br> Which graph shows the solution region of this system of inequalities?
ELEN [110]

Since the values on both sides are different, hence graph of option C is correct.

<h3>What is inequality?</h3>

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Solutions to inequality graphs

Inequalities are an equation that does not include only the equal sign.

The system of inequalities are;

y \geq 2(1.3)^x\\\\y\leq -x^2 + 4x + 5

The first function is an exponential function.

Since the values on both sides are different, hence graph of option C is correct.
