Problem 4: A father left 1⁄2 of his estate to his daughter, 1/3 of his estate to his grandson, and the remaining $45,000 to charity. What was his total estate?
Problem 5: Find the equation of the line that contains the point (-7, 6) and is perpendicular to the line ???? = 2.
Problem 6: Determine algebraically whether the function is even, odd, or neither even nor odd.
????(????) = −???????????? +???????????? −????
Problem7:Solve: |1−2????|+4=9. 23
Problem 8: Find the equation of the line going through the points (-7, 6) and (-1, 3). Jules has two jobs: one pays $11.25/hour, and the other pays
$9.50/hour plus 60% of the hourly pay in tips and bonuses.
Problem 9: Write an equation that describes Jules’ total take-home pay in terms of the number of hours work at the first job and the number of hours worked at the second.
