Given the quadratic function, its graph or other information, determine the x- intercepts are: Whole numbers, Integers, Rational, Irrational, or Not Real.
Determine the nature of the x-intercepts: f(x) = x² + 4x - 24*

Which system of linear inequalities is represented by the graph?

Each month, a shopkeeper spends 5x + 14 dollars on rent and electricity. if he spends 3x−5 dollars on rent, how much does he spend on electricity? for which value(s) of x is the amount the shopkeeper spends on electricity less than $100? explain how you found the value(s).

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
