Write an equation of the line passing through point P that is perpendicular to the given line.
P(4,−3), y=−x−5

The table shows the balance of a money market account over time. write a function that represents the balance y(in dollars) after t years.

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Two years ago a man was six times as old as his daughter. in 18 years he will be twice as old as his daughter. determine their present ages.
